First $10k+ wildlife lens purchase

If I was going to be shooting in/around Yellowstone and in the market for a big prime, I think I’d go with the 600mm F/4. In Nikon’s lineup, I would pair it with the 400mm 4.5 as a great complimentary, reasonably fast prime. Regarding video, I think you might be surprised by what Nikon offers in the recent bodies. I’m continuously impressed with the video output and stabilization. I’ve been able to handhold 600-700mm that looks like it was on a gimbal. Obviously what can be handheld is highly dependent on the person. Canon‘s lens lineup wasn’t really fitting my wants so I was between Nikon and Sony when switching systems. Nikon won out with the lightweight and small telephotos.
 
I have shot with the midrange PF lenses and the 400 f4.5.

They are all good lenses super sharp. The problem is they don't have the wide aperture of the big primes. It means when you add the tc their wide aperture goes way up especially with the 2x.

It has also been my observation that once you get to 800 you are better off cropping or dx than trying to go longer with another tc. Things like atmospheric disturbance or the exaggerated effect of minor motion on image sharpness affect the ability to get farther. There is a practical limit to how long you can shoot with camera lenses in atmosphere. You do better by finding a lens that is sharp enough to stand significant cropping and forget about using a tc to get what is practically reachable under the circumstances. Or maybe stop your super lens down slightly to increase sharpness. Or shoot in outer space and pick things to shoot that don't move around.

I have the 800mm pf which in my opinion is as good as anything at that focal length. It is 6.3 which is close to the widest aperture you are going to get using any lens. The super expensive f mount 800 does 5.6 but it is not that much of a difference.

If you use the 600mm pf it is max 6.3 at 600 which means once you add the 1.4 you are now at f9. Use the 2x and you are now at f13.

The best way to get the best results at 800 or above is to pick the lens that is the sharpest at 800 and has the widest aperture. Both the 600mm f4 and the 400 f2.8 with an either 1.4 or 2x tc will still have wide aperture.

Tests have been done comparing both super prime lenses at 800 with the native 800 pf. My recollection is they are all pretty close with the native 800 having perhaps a very slight advantage.

I think if you are going to shoot birds a lot my personal opinion is you need something super sharp at 800. The 600mm tc works for that and you have the added advantages of also having a super sharp and super wide open 600mm. You don't need the 800 with the 600mm tc.

On the other hand having the 600 only benefits you if you are going to shoot a lot at 600. If you have a lot of stuff shorter than 600 then you will probably do better with the 400mm because it acts like a zoom when you throw the tc switch. You have a solid 400mm and 56omm lens.

It all depends on what you will shoot. Most likely if you have the 800 and 400 tc you will probably not need to use an external tc because if the 800 is too long the 400 will handle it and you could always crop to make the difference.

The cost of these big lenses is weight and length. You are going to have to plan to carry the weight and use stabilization. You will in effect need to have two lenses at hand. Maybe that means you pack all that in in a good backpack and once you get there set up your mini blind. Maybe shoot from the ground sometimes using bean bags. Or two tripods two bodies and bring a sherpa.

Everything has a tradeoff. You want convenience and comfortable hand holding you lose wide aperture. You want wide aperture you pay for it in weight and inconveniences.

There is no such thing as a free lunch. Nothing no matter how expensive gives you everything.
 
So the lady in charge finally approved a $15,000 budget. I've been shooting slow zooms for the better part of five years now as a semi-serious hobby, but I'm looking to step things up a notch as we recently bought a little property near Yellowstone. Started with the Fujifilm X-T3 and their 100-400mm, graduated to full-frame with Canon's R5 and 100-500mm, and presently I'm shooting Sony's A7RV with their 200-600mm. I've never owned a large supertele prime, but I'm ready to make the transition. When photographing critters at dusk, especially owls, I've been frustratingly limited by the slow zooms. I'm excited for those buttery backgrounds and low-light opportunities out here.

I'm leaning towards a) keeping my Sony A7RV and purchasing either the 400mm f/2.8 or 600mm f/4 GM along with their TCs, or b) starting fresh with Nikon and that stellar wildlife lens lineup we've all been lusting over in the other forums. I would opt for either the 400mm f/2.8 TC or the 600mm f/4 TC in Nikon, as well, and I'd pick up a 2x TC for added versatility. If I go with Nikon I would add some of their PFs down the road, whereas I don't really have many mid-range options if I stay with Sony, outside the 200-600mm.

My primary concern with Nikon is their lack of emphasis on video and no real upgrade path in a cinema line. I'm splitting my time pretty evenly these days between stills and video, and I like the idea of graduating eventually to the FX3 and adding a dedicated video camera with Sony. I've also gotten used to the smaller form factor cameras with Sony, which doesn't make a huge difference when a large prime's attached, but I really appreciate the smaller cameras when switching lenses or running a dedicated video rig. Downsides to Sony at the moment are the lack of wildlife lenses and not catering to this niche as much as Nikon does.

Finally, I realize the 400mm vs. 600mm discussion is an age-old debate among photographers, and it ultimately boils down to subject and framing preferences, and I've read through many many threads on that already, but I still have yet to decide for myself. I really like the idea of versatility with that 400mm f/2.8 but 400mm is usually short, in my limited experience. I shoot a lot of raptors out here, which would benefit from the 600mm, but I'll also be shooting all the large mammals in Yellowstone, as well. As mentioned above, I want as much background separation as possible and to stay out as late as I can, so I worry even that f/4 at times won't be enough. I also worry 600mm would be a trickier composition to navigate since this will be my primary wildlife lens for a while. "Buy the lens in the focal length you'd shoot without relying on TCs" is the advice I see from veterans like Steve Perry, but I'm not really sure what that translates to in Yellowstone with the wide variety of critter sizes and distances.

If you guys could start over in my position, what would you do? And what advice would you offer yourself in this position when starting out with long wildlife primes?
Having gone to Yellowstone for photography only a couple times, my impression is the longer the better. In fact, on one of my trips to Yellowstone I rented the Nikon 800mm f/5.6. I ended up using it most of the time with the paired 1.2TC that came with it. I did lust for that lens for several years afterward but its price and weight kept me from getting it. When Nikon announced the 800mm PF for $6,000 weighing only 5.2 pounds, I couldn't resist. I have used it quite a bit since I got it about a year ago, often with a 1.4 or even the 2.0 TC. Most of the time with a tripod though in a pinch, handheld. I also have the 400mm f/4.5 which I can use for closer and larger animals. I do think about buying either the 400mm f/2.8 TC or the 600mm f/4 TC for low light situations. Probably I would choose the 400mm f/2.8, it is lighter and could be used when light is much lower. However if I was primarily shooting in Yellowstone, I would go for the Nikon 800mm PF. Hoping to get back there now that I have this lens. Good luck on your decision.

I have the same setup and I have the same reaction.

The one thing that is better about the 400mm f4.5 is that it is super light and super sharp and works well with teleconverters. It is by far the most compact and best balanced long telephoto lens I have ever used.

I had all three of these superlight lenses, the 400 f4.5, the 600mm pf and the 800mm pf. I found I was using the 800 most of the time. The nice thing about the 400 4.5 is that it is super light and compact and works well with tc's. I think adding the 400mm f2.8 to this mix would give you the option to pack heavy or light,.

If you are working with the 800 on a tripod and gimbal you could have the 400 f4.5 by your side on a separate body and quickly bring it up to shoot if something closer appears. I could see that on a blackrapid shoulder strap. If you need something a bit longer add the 1.4 tc or go dx or crop.


The 400 mm f2.8 could be in your pack in the car and brought out when serious work is needed. You may be able to work that with a monopod while your 800 is on a tripod. Or crawl on the ground with either of them when you want to get low.

I made a decision recently to sell my 600mm pf. I found the lens got very little use once I got the 800. It only had an advantage over the 400 at 600mm and I always would prefer the 800 at 800 and above.

To me the big deal with these super teles is the background rendering as well as the top of the line sharpness. I am less concerned about shooting in low light. I have found I can shoot effectively at higher iso with the Z9 and these lenses. Noise is easily cleaned up in post most of the time.

I need to rent the 400mm f2.8 and give it a good run to see what I think.

Living beside a place where others have to save money to be able to afford being there once for a couple of weeks and still being able to think about this kind of lens ... Wow, what kind of two privileges ! My advantage not having to ask anybody for permition becomes almost negligible ... ;)

FWIW, the conflict with choosing the focal length of the personal "top gun" is independent from the brand. Because of the place where I live and the general situation of life I have by far less oppoorunities to go shooting the way you probably have, but there is still something that might be the same. If I have the chance to go for planned shootings from tent/hide being there well before daylight, my 500 f4 seemed to be just right or sometimes even a bit too long. The more "spontaneous" it got the more often I got in the sutation where 500mm seemed too short and I wished I had something longer ... but at the same time - because sometimes even being on the move - something lighter and handholdable.

The second thing is, that whenver shooting stationary with long lens from a hide, I experienced the photography version of Murphy's law. The big gun is positioned for the primary target and suddenly something unexpected happens beside it, that I can't reach with the big one (Too close, other direction,...). In this case I was happy to have second body giving me a maneuverable setup to take the extra shots heldheld, wile having the big one prepared. It's basically the same thing that @wotan1 mentioned above.

After changing to mirrorless just recently I can't afford the second body not bcause the lady in charge, but because of the wallet having an empty stomach.

Just like @wotan1, I can't speak for other brands, but - forgetting the second body for a while - if I had the money for this kind of lens I would go with the 400 f2.8 TC in combination with a second, external TC. Why ?

Because despite of all discussions around TC's, due to the superior IQ of the top notch super tele primes today they have enough headroom to be used with TC's and beside the flexibility with switchable internal TC, the extra stop of light may be just as important for shooting wide open in really dim conditions.

But what's really best for you nobody can really tell. If you got out with the 600mm and teh bison comes too close , you can do nothing but shooting a passport photo, if you go out and discover this precious little bird that nobody ever saw in your place, and you have nothing but a 400, you end up with an image that would fit on a stamp ... you never know.

All the best with your decision (y).
Today I am sad not having to take a decision like you because I don't have the money, but I also feel a little bit happy about not being in your shoes ;)

My experience suggests that it depends largely on the subject matter and location. So, for example if you are intending to shoot large mammals proximate to access (read trails/roads) an 800 is typically too much lens. Now, change it to remote packing and following wolves and it's a different story. Again, my advice holds namely check the FL you shoot most often and if one is looking to expand the subject matter, study what FL's are most typical. These days, the TC's (and the lenses) have improved so dramatically that using a 2x TC now becomes feasible so a 400 f/2.8 becomes a viable option. If I had a binary choice between it and a 600 f/4 the optical and performance differences are minute so it becomes more of an issue of the desired FL's that one shoots most often.

I shoot a little of everything in Yellowstone, which is why I take a supertele and a 100-400 zoom. If I'm hiking long distances, it's just the zoom but for under a mile, it's both.
 
Is the base range as important as it used to be with regards to image quality? Are we getting to the point, at least with these Nikons, where you can still have your image quality by using the TCs? Genuinely wondering as I haven't used them personally yet.
You’ll get a lot of opinions on TCs. Generally, the 1.4 Z is deemed very good to excellent and the only drawback is the aperture loss and whether tha5 affects bokeh. The 2x gets less enthusiastic reviews. However…and I admit the pixel peepers are right…at 2:1 on a 5K monitor one can see very slight sharpness loss with the 1.4 and a bit more with the 2x. That said…outside of pixel peepers nd during post work…nobody looks at images at 2;1…and my decidedly non scientific tests with both TCs reveal essentially no difference in sharpness once the final image is downsampled for the screen…might be a little different looking image but it’s just different, not better/worse. IMO…in good light the TCs are just fine and in medium light today’s NR software handles the higher noise due to aperture or ISO. If you look at my members gallery…I think I posted the red headed woodpecker BIF shot…tha5 was with the 600PF and 2x on either my Z8 or Z9 and then cropped to a b8t inside the DX box. For screen output…it’s perfectly acceptable to me…and it would be for print if I did that. Given I’m not willing to both carry the 600TC and the tripod it really needs and suffer the what does that cause me to leave behind because of the weight…I take the 600PF and have no issue with using the TCs although I will try to get closer before using the 2x if possible…but many times tha5 just not in the cards…so I will both use it and also take environmental shots in addition to portraits.

Theres been some other talk about M43…and while it is lighter and smaller I‘m not yet feeling old enough to accept the limitations that come along with it…but TBH for screen output I’m sure I would find it quite satisfactory…and I reserve the right to buy some when my body finishes not holding up its end of the “I’m not getting old“ deal.

Exotics or primes or zooms and TCs or not…all depends on individual needs, wha5 you’re willing to carry, and budget to some extent but the first two are more important.
 
The more I think about it, I’m starting to lean towards a 600mm f/4 over a 400mm f/2.8 for Yellowstone. When you go through the species list, bears and wolves are always at a distance; raptors are at a distance; elk and bison are typically close but large and slow moving, so I could move back to get the right framing; antelope and big horns are small enough even if they’re close, and I could move back to frame them. Foxes, coyotes, swans, ermines, moose, rare critters like wolverines or cougars—all either small or at a distance.

I’m just wondering if I’ll regret giving up that stop of light at f/2.8 for chasing owls at dusk. I keep coming back to that and don't have any experience with a 600 f/4, so I don’t know the answer to that. Would be curious to hear from anyone who shoots a 600mm f/4 and chases critters or raptors at dusk if they ever feel they need more speed/light.
 
This decidion becomes more nuanced when you include the advances in post processing denoise and sharpening software. I live in a region where heavy cloud cover and shorter days are more the rule than the exception. I have always placed high value on a wider aperture lens but this is changing. The most important aspect of the wide aperture has become subject isolation from the background. The obvious drawback is weight. Brad Hill recently compared sharpness of all the Nikon long lenses that can provide 400, 600 and 800 mm focal lengths. The only lens described as "professional choice" was the 400 TC 2.8 (using TC20 at 800mm) We all use our equipment differently. Over almost a full year, LR tells me I use 400 mm 43%, 560 mm 52% and 800 mm 5% of the time. 1120 mm accounted for less than 0.15% of my images. I likely shoot more environmental type images than a lot of other photographers where the subject may be filling less than 25% of the frame. Even for eagles and hawks, I find that locating and setting up near their hunting grounds gives me better images at 560 mm than trying to get in flight shots at 800 mm. Those with better technique probably do better at 800 mm. The weight difference between a Z8 and Z9 body is not that big a deal if you are using either of the Z internal TC lenses. If hiking is part of you normal photography, a Z8 with the longer prime might be a best choice.

Been reading a lot of Brad Hill's commentary on the two lenses. He's a great resource and I know uses the 400mm f/2.8 TC for his work due to shooting a lot of larger bears and mammals, many times from the zodiac. Not sure where you read that he doesn't think the 600mm f/4 is a "professional choice," but I'd like to see that commentary if you can find it, please. He does rank the 600mm f/4 TC above the 400mm f/2.8 TC for sharpness at both 600mm and 800mm. (600mm: http://www.naturalart.ca/galleries/latest/detail_8.html).

"But right now I can spill the beans on how these different 600mm(ish) options compare in one aspect of optical performance - image sharpness. If we limit the discussion to overall image sharpness (considering both central region and edge sharpness) it turns out the 6 Z pathways to 600mm(ish) rank exactly in the order listed above, with the Z 600mm f4 being the sharpest 600mm option and the Z 100-400mm f4.5-5.6 with the Z TC-1.4x being the least sharp or softest.

Z 600mm f4 TC VR S = 600mm
Z 400mm f2.8 TC VR S with TC engaged = 560mm
Z 600mm f6.3 VR S = 600mm

He also ranks the 600mm f/4 TC as the sharpest 800mm option above the 400mm f/2.8 TC (800mm: http://www.naturalart.ca/galleries/latest/detail_9.html).

@Steve, if you get a chance, I'd love to hear your thoughts on this little summary I'm arriving at for the Nikon 600mm f/4 TC in Yellowstone:

I did not mean to imply that the 600 prime was not a very sharp lens. My comment was the 400 TC 2.8 was the only lens categorized as Professional choice AT ALL THREE FOCAL LENGTHS. This is as much a opinion about versatility as sharpness. To continue to Brad Hill's comments on the 800 mm choices;

"The first cluster I'll call the "Professional's Choice" cluster - it includes the first 3 lenses on the list, so the Z 600mm f4S with its TC-engaged, the Z 400mm f2.8S with the Z TC-2.0x, and the Z 800mm f6.3S. The difference in sharpness between these three lenses is minimal and very nuanced - and it varies with aperture used, distance to subject, etc. And, anyone good at post-processing (and in particular, in image sharpening) could reduce the sharpness difference to virtually unnoticeable. It's also notably that these 3 options have the largest maximum apertures (f5.6 to f6.3) of the 7 pathways (which makes them a little more "usable" in a field setting."

It happens that I was on the photo tour when the wolf image on this blog post was taken. There were 6 photographers plus Brad. There were seven Z9 bodies and five 400 TC 2/8 lenses. The consensus was that this was a perfect kit FOR THAT SPECIFIC TRIP. The different lens choices exist because we photograph different subjects in different light in different locations. I do not recommend any specific gear to others. I just intended to share my experience with and opinion of the 400 TC 2.8.
 
I did not mean to imply that the 600 prime was not a very sharp lens. My comment was the 400 TC 2.8 was the only lens categorized as Professional choice AT ALL THREE FOCAL LENGTHS. This is as much a opinion about versatility as sharpness. To continue to Brad Hill's comments on the 800 mm choices;

"The first cluster I'll call the "Professional's Choice" cluster - it includes the first 3 lenses on the list, so the Z 600mm f4S with its TC-engaged, the Z 400mm f2.8S with the Z TC-2.0x, and the Z 800mm f6.3S. The difference in sharpness between these three lenses is minimal and very nuanced - and it varies with aperture used, distance to subject, etc. And, anyone good at post-processing (and in particular, in image sharpening) could reduce the sharpness difference to virtually unnoticeable. It's also notably that these 3 options have the largest maximum apertures (f5.6 to f6.3) of the 7 pathways (which makes them a little more "usable" in a field setting."

It happens that I was on the photo tour when the wolf image on this blog post was taken. There were 6 photographers plus Brad. There were seven Z9 bodies and five 400 TC 2/8 lenses. The consensus was that this was a perfect kit FOR THAT SPECIFIC TRIP. The different lens choices exist because we photograph different subjects in different light in different locations. I do not recommend any specific gear to others. I just intended to share my experience with and opinion of the 400 TC 2.8.
I appreciate your perspective. I'm not so worried about the sharpness equivalence between these lenses, honestly, as it seems they're all fantastic. I'm sure I'd never know the difference between any of them in practice.

I am interested in the portion of your comment where you mention the only lens he described as a "professional choice" was the 400mm f/2.8 TC, implying he didn't think the 600mm f/4 TC met that standard. Are you saying it's the only lens that he calls a professional's choice for all three of those focal lengths? That's true of course because the 600mm can't shoot at 400mm. It makes sense that you'd shoot a 400mm f/2.8 from a zodiac for shore mammals, but if he's saying he doesn't consider the 600mm f/4 to be of the same quality as the 400mm f/2.8 then that concerns me and I'd love to see that commentary before making my decision.

I started out shooting wildlife with a Nikon D500 and 200-500 f5.6. Pretty soon I got the 400 f2.8 and 1.4tc. A year later I got a D850 and 600 f4. All along from the start my friend had been saying just get the 850 and 600. Obviously I was starting out and needed to make sure I was going to stick at it. But I should have skipped the 400. For wildlife reach is like CI in cars. It’s usually much easier to take a few steps back to fit something in than trying to sneak closer to fill the frame.

I’d say get the best quality longest lens you can afford. Currently in today’s market that is the Nikon 600 f4 tc. And since it sounds like you can, then match it to the best Nikon body, the Z9. Then work back for shorter stuff. I have the Z9, 600 f4 tv and 100-400 4.5-5.6. I also still have the 400 2.8 but it hardly ever gets used, only if I am very very specifically targeting something. I hand carry and handheld shoot the Z9 600 combo and have the 100-400 and macro in a backpack. Covers pretty much everything.

If you’re concerned about video watch some Z9 video on video. It’s amazing. And now with the 600 tc I’ve just started shooting video. With all of the stabilisation I can handhold at 600mm pretty damn smoothly and as it’s 4 or 8k do more stabilisation in post. Also there is a great smooth power zoom option in body, 120fps 4K slomo and 2.3 crop mode.

That's helpful insight, thank you. I'm still open to the 400mm f/2.8 TC but I'm definitely starting to lean towards the 600mm f/4 TC for these reasons. Seems to me, when you run through all the species of Yellowstone like I did (mostly) above, it would be far easier like you said to step back and get the framing I want for the larger, slower bison and elk. I could see an occasional coyote running at me along the roadside becoming a framing issue with the 600mm as they usually get pretty close in those instances, but it would also become a framing issue for the 400mm in that case. Everything else it seems like I'd want the extra reach.

With the 400mm f/2.8, you get the extra stop of light and three usable lenses in one (400mm, 560mm, and 800mm with 2x), but most of my shots will be using the TC engaged or stacked, and I'd have to fiddle with the external TC to get my 800mm. With the 600mm I'm in the sweeter spot of the range for this location, I've only got two usable lenses in one (600mm and 840mm), but I don't have to mess with an external TC and I've got marginally better sharpness and likely marginally better contrast/rendering than the stacked 400mm f/2.8.
 
So the lady in charge finally approved a $15,000 budget. I've been shooting slow zooms for the better part of five years now as a semi-serious hobby, but I'm looking to step things up a notch as we recently bought a little property near Yellowstone. Started with the Fujifilm X-T3 and their 100-400mm, graduated to full-frame with Canon's R5 and 100-500mm, and presently I'm shooting Sony's A7RV with their 200-600mm. I've never owned a large supertele prime, but I'm ready to make the transition. When photographing critters at dusk, especially owls, I've been frustratingly limited by the slow zooms. I'm excited for those buttery backgrounds and low-light opportunities out here.

I'm leaning towards a) keeping my Sony A7RV and purchasing either the 400mm f/2.8 or 600mm f/4 GM along with their TCs, or b) starting fresh with Nikon and that stellar wildlife lens lineup we've all been lusting over in the other forums. I would opt for either the 400mm f/2.8 TC or the 600mm f/4 TC in Nikon, as well, and I'd pick up a 2x TC for added versatility. If I go with Nikon I would add some of their PFs down the road, whereas I don't really have many mid-range options if I stay with Sony, outside the 200-600mm.

My primary concern with Nikon is their lack of emphasis on video and no real upgrade path in a cinema line. I'm splitting my time pretty evenly these days between stills and video, and I like the idea of graduating eventually to the FX3 and adding a dedicated video camera with Sony. I've also gotten used to the smaller form factor cameras with Sony, which doesn't make a huge difference when a large prime's attached, but I really appreciate the smaller cameras when switching lenses or running a dedicated video rig. Downsides to Sony at the moment are the lack of wildlife lenses and not catering to this niche as much as Nikon does.

Finally, I realize the 400mm vs. 600mm discussion is an age-old debate among photographers, and it ultimately boils down to subject and framing preferences, and I've read through many many threads on that already, but I still have yet to decide for myself. I really like the idea of versatility with that 400mm f/2.8 but 400mm is usually short, in my limited experience. I shoot a lot of raptors out here, which would benefit from the 600mm, but I'll also be shooting all the large mammals in Yellowstone, as well. As mentioned above, I want as much background separation as possible and to stay out as late as I can, so I worry even that f/4 at times won't be enough. I also worry 600mm would be a trickier composition to navigate since this will be my primary wildlife lens for a while. "Buy the lens in the focal length you'd shoot without relying on TCs" is the advice I see from veterans like Steve Perry, but I'm not really sure what that translates to in Yellowstone with the wide variety of critter sizes and distances.

If you guys could start over in my position, what would you do? And what advice would you offer yourself in this position when starting out with long wildlife primes?



Sony, Nikon, Primes wild life, video, stills, low light, reach, weight, size, decisions, needs versus choices = capability.

"If you guys could start over in my position, what would you do? And what advice would you offer yourself in this position when starting out with long wildlife primes?"

Short answer, RENT BEFORE YOU BUY

Myself the 400-600 PF lenses, Cameras ZF for low light 14 fps, Z7III hopefully with the Sony 61 mp sensor, in the short term the Z8, why because i would in my situation use that system more often and effectively as apposed to the exotic expensive primes on a Z9, if i needed a 400 TC-600 TC i will rent it as i currently do with any exotics.


A couple of club members are getting wild life stills 30mb files from Video on their Z9..................using PF glass and just loving it.

Your doing 50 - 50 stills video already ?

The Z9 is excellent as you know for Video but the Z9 II ? is possibly about to land, well this year ?, i assume along with many other feature upgrades it will have more stops of VR and Low light focusing along the lines of the ZF, who knows.

You do Lower light dawn dusk as you say, so light gathering performance is as we know needed, it can be derived with lenses or cameras or both, how much compromise if at all is the consideration.

Choosing 400mm or 600mm is a never ending issue for many people, myself with 60 mp or 45 mp i would rather crop as i don't think 200 is as big a issue for some applications, often the only option is maybe add a pinch of compromise and move on.

That said if i had to choose a exotic to buy its the 600mm F4 TC, but gee the 600 PF being optically almost matched at 600mm for a lot less money and weight, mate hello again to a fraction of compromise if at all.

The 400 PF in rendering backgrounds is close but not perfectly matched to the F2.8, for the price of one exotic you could end up with a Z8 on a 600 PF and even with a little more permission as you say have a 400 PF on a ZF, happy days.

As we know size and weight of gear for hiking and traveling is important and Nikon has listened.

This week i sold my Z9, my girlfriend paid for it in December 2021 as a Xmase present.

Again for myself what i would consider is ............Nikon has a great selection of optics especially in the PF range, small light compact, they also have smaller cameras.

On another point, Sony has just raised the betting levels with the stunning 300 F2.8, if feel its only the start and there will be much more to come as it will be with Canon, and with the new technology direction of the A9III, switching brands may not be a wise thing just yet.

In your case Sony is important especially if one is doing more video, which i am not.

An observation of features emerging that has my attention to look out for is, the ZF, 8 stops of stabilization not 5, 10 stops of low light focus not 5 all on a larger pixel pitch 24mp sensor with a series 7 processor, 14 fps?

OK the ZF its not going to wet your lips for your wild life set up and yes the tracking isn't a Z8, Z9, the two key points of the ZF has are interesting features of what may be coming in the next generation Z7III Z8 Z9, the two key features in the ZF alone certainly add to or compliment the light 400 F4.5, 600 F5.6, 800 F6.3 PF lenses and work in with that very light compact glass with good performance in lower light and video, now the ZF being 24mp has incredibly good ISO, i don't need or don't have a use for a 400 F2.8 TC 600 F4 TC that often.

Please the ZF is not for you, just a preview of what may be coming.

The ZF you can hand hold doing a water fall shot and have the water soft, no tripod needed as traditionally done. So again gathering light for the sensor technology and VR - IS etc compliments the PF range of glass.

2025 2026 will see some real new changes coming, the new Z9 is not far away i hear it will also be much higher in price.

Nikon is interesting on glass, Sony i starting to chase them down.

Optically the 600 PF is so close if not almost the same 600 F4 TC. But yes then one says but the rendering, ok AI post gets you there as does Topaz.

As Steve says marry the glass date the camera LOL.

I have sold my Z9 a few days ago, no regrets as its a clean new garden i can now sew again, its a brilliant tool, a) if selling the time is now, b) i don't need that much video tool c) while i have the strength and hand size of Dwayne Johnson weight for hiking or traveling is still not preferred, c) i can walk for 10 hours with the Z9 on my 200-500 push pull but i would rather carry a second camera body and different lens.

In the short term i have ordered prior to the significant price rise announced 1st or March a Z8 as a temporary bridge camera, at least i can use it everywhere especially traveling and hiking, plus it helps compliment the cabin luggage limitations 400 grams here 200 here 300 there all adds up LOL.

My end game aspiration is heading for the Z7 III subject to the size and resolution and a ZF for discrete low light general photography option, both on the 400 or 600 PF kind of glass with a 70-200 F2.8 FL i currently have. If i need a speed demon in the future i will rent or borrow as i often do with the DSLR 600F4 FL and even a D6.................while i respect the new focusing - tracking technology its not something i am fully or partly dependent on.

I mean have a look at Steve's money shots from his Sony gear..........camera gear are all just tools and the good the bad the ugly comes from YOU 90% of the time.

I would rather use a 600 PF on a ZF and get 28 out of 30 money shots than a Z9 on a 600 F4 TC with a tripod and get only 12 out of 30 opportunity's.

ONLY an opinion.

If there is only one lens to choose, its then like i said the general sweet spot for wild life is 600mm.

Wild life shooters complain more about wanting longer reach even at 600mm, so the Tc will come in well.

Again that said try the 600 PF before you buy your exotic, its optics are magical and in many situations you may not pick a difference.

You can always use it for 6 months then sell it if need be.

To me the 300 2.8 at F2.8 does the same as a 600mm F4 at F4 as far as DOF - back grounds go.

MTF charts are interesting to look at.

Only an opinion
 
Yellowstone - what mammals - bison are big and easy to find closer in, but what about the smaller ones or ones you can't get too close too?

And what about ease of moving around? And travel with your equipment to Yellowstone?

Lots of little things to consider.

Maybe you are better off with a 400 4.5 and 800PF.

If you decide on 600, try the 600pf before you buy the exotic just based on weight. It's 45% of the weight of the 600 f4. I sold the 180-600 for the weight reason and kept the 100-400 for weight, close focus, and ease of travel.

You have so many options, and the input here is great for adding to your clarity and confusion. Only you can figure out what works for you.

This link can give you some perspective as well based on his real world work.

Brad Hill on your options and ranking.

Good luck, sounds like you need a dozen espressos for this task.
 
The more I think about it, I’m starting to lean towards a 600mm f/4 over a 400mm f/2.8 for Yellowstone. When you go through the species list, bears and wolves are always at a distance; raptors are at a distance; elk and bison are typically close but large and slow moving, so I could move back to get the right framing; antelope and big horns are small enough even if they’re close, and I could move back to frame them. Foxes, coyotes, swans, ermines, moose, rare critters like wolverines or cougars—all either small or at a distance.

I’m just wondering if I’ll regret giving up that stop of light at f/2.8 for chasing owls at dusk. I keep coming back to that and don't have any experience with a 600 f/4, so I don’t know the answer to that. Would be curious to hear from anyone who shoots a 600mm f/4 and chases critters or raptors at dusk if they ever feel they need more speed/light.
I live near the park, so I can go there a lot. Going there a lot means that bears and wolves are not always at a distance. Going there a lot might mean you get more comfortable leaving the 90 plus percent of the visitors who don't leave the asphalt or boardwalk behind. And then, magically, when you're in the back country, the wildlife is closer. I have Z9 and Z8, the Z 400 f/2,8 and both Z TC's and the Z100-400. Believe I am set for what I want to be able to do.

It is kind of a werid analogy, but it seemed excruciating when we tried to choose wall paint color for a needed update at the house. After you commit to one, and relegate all the swatch cards to the trash so that you no longer have Silver Spruce, Stone Silver, Aspen Hush, Seaport and Ecological Green staring back at you, you never think of them again. I get the images I can get with the gear that I have, and so far, have never felt that having the native 800 would have significantly improved an image I brought home. For me, the gear now is so good that the last nuances of differences between the various options is likely smaller than the room there is for skill improvement/development on my part with what I have.

Slightly off the main topic, but I will note that when you pull off the Grand Loop Road, and mount an exotic prime telephoto on a gimbal, you will make a lot of new friends. And they will be disappointed in you when they learn you are looking at an owl not the grizzly bear they've been looking for their entire trip. ;)
 
I see you found the Brad Hill info but for others, I realize now the Brad Hill info is hard to find.

Scroll down this page

He tells you which image you need to find. For example for the 600 it's Black Bear on a log, and the 800 its the 3 wolf pups.

He groups the lens into clusters, for example on the 600:
I'll call the first cluster the "Professional's Choice" cluster - - it includes the first 3 lenses on the list, so the Z 600mm f4S, the Z 400mm f2.8S with its built-in TC engaged, and the Z 600mm f6.3S. The difference in sharpness between these three lenses is both very minimal and very nuanced - and it varies with aperture shot, distance to subject, etc. And, anyone good at post-processing (and in particular, in image sharpening) could reduce the sharpness difference to virtually unnoticeable. It's also notably that the two of these three options have the largest maximum apertures (f4) of the 6 pathways (which makes them a little more "usable" in a field setting).

and the 800

The first cluster I'll call the "Professional's Choice" cluster - it includes the first 3 lenses on the list, so the Z 600mm f4S with its TC-engaged, the Z 400mm f2.8S with the Z TC-2.0x, and the Z 800mm f6.3S. The difference in sharpness between these three lenses is minimal and very nuanced - and it varies with aperture used, distance to subject, etc. And, anyone good at post-processing (and in particular, in image sharpening) could reduce the sharpness difference to virtually unnoticeable. It's also notably that these 3 options have the largest maximum apertures (f5.6 to f6.3) of the 7 pathways (which makes them a little more "usable" in a field setting.

The second cluster? Includes just the Z 600mm f6.3S paired with the Z TC-1.4x and the Z 400mm f4.5S paired with the Z TC-2.0x. I'll call it the "Pretty Darned Good" cluster. The difference in sharpness between these two 800mm(ish) options is extremely minor, but both are noticeably less sharp than the lens in the first cluster (when viewed at 100% magnification on a quality editing display). A LOT of folks would be absolutely pleased with the sharpness of the lenses in the second 800mm(ish) cluster. But...keep in mind these two 800mm(ish) pathways have a maximum aperture of f9...which can limit their usefulness in a field setting.
