Nikon 400/4.5 & Z Teleconverter Question

As I mentioned, this all started when a well priced 500PF came up for sale but was sold before I could have it pulled. I do not have a Z50ii, but I still have my D500. I can use it with that or trade it in and that would get me closer to the price of a new Z50ii.

I use a 500pf with my D500 and recently added a Z8 and FTZ II and am very happy with the performance of this lens on the Z8. There are plenty of used copies about so if I were in your shoes, I’d keep my powder dry and wait until the right 500pf comes up. Especially if like me, you plan on keeping the D500.
 
I had thought that as well. But I also have a gap in native lenses above 120mm, and I often shoot some casual landscape shots when I am out shooting BIF. So I need to decide if I want something more versatile, or dedicated to BIF. The 186 is definitely more of a dedicated lens for BIF for me given its size and the need for something like a monopod or tripod if I am taking more than a shot or two. I need to start testing some of my older F-mount glass to see how well it can fill this gap.

--Ken
The gap between 120mm and 180mm is pretty whatever. If 120mm isn't long enough, it won't be like 180 is too long.

I have not yet decided about the D500. Right now it is the only pixel dense body I have, so I do not want to get rid of it until I have some set-up that works well enough for BIF.

I have been looking to replace my Nikon 200-500 lens which I use for birding. I have been both researching and looking at some options available for sale. I have both F and Z bodies, and the two that I primarily use for BIF are the D500, and now the Z6iii. I am trying to use the latter as my main body as I prefer the AF system, but I have not made any decisions about the future of the D500. I never warmed up to the D500/200-500 combo and while that lens performed better on the Z6iii, I would still like to see about other options that will not completely break my wallet.

I have been considering a trade up to a180-600, but that would leave me with just the Z6iii and its 24MP sensor. I recently had a line on a used 500PF, which I thought would be a good solution as it can be used with both bodies, but it was literally sold while I was in the midst of responding. Now, an opportunity has also come up for a used 400/4.5 S lens at a good price and that got me to thinking about a future1.4TC purchase to give me a bit more reach with the Z6iii. I previously found the 500mm FL of the 200-500 on a DX body to be a good fit for the birding opportunities generally available to me.

Having used the TC14ii and TC 20iii in the F-mount, I am very familiar with giving up IQ for reach, and never found either TC to be of great value when it comes to IQ. But almost everything I have read or watched about the Z-mount TC's seems to indicate that they are much better at minimizing any IQ loss. And, there are a decent number of reviews here, in other forums and by folks who have YT channels that do not try to sell any and everything they post about, that the 400/4.5 with the 1.4TC produces images about equal in IQ to the 500PF and the 180-600.

But what I do not fully understand is that after praising this combination and displaying images that look quite good, many will go on to say that if you are going to primarily shoot at a focal length of, or around, 560mm, then it is better to buy a lens that can hit that focal length without a TC. I could understand this advice if we are talking about F-mount lenses, or a known bad combination of lens and TC, but why say this right after elaborating about how this specific combination loses little to no IQ as well as showing sample images that seem to support these statements? After all, we are discussing a specific combination and not talking in generalities.

Apologies if I sound a bit frustrated, but if the IQ is supposedly there, and assuming the lens/TC combination is not expected to be hammered daily and/or used in harsh conditions, what are the reservations about this combination? If it is the exception to the rule, then say so. But to say that it is a great combination, and then say that you would still recommend otherwise seems to send conflicting messages. Did I miss the elephant in the room?

--Ken
I am going to say this, the 400 f4.5 with 1.4TC does not produce the same IQ the 500pf produces natively. I have used both lenses and the PF is sharper. That said, the 400 f4.5 is plenty sharp on its own, and does well with the 1.4TC. BUT ..if your goal is getting past 500mm then your much better off with a used 500pf with 1.4TC or the 600PF which unfortunately is somewhat expensive option. The one strength the 400 f4.5 has over the 500pf is a slight AF advantage , but it's not a huge difference. Good luck
 
I have the 400mm 4.5 and both teleconverters. I have the 1.4x pretty much bolted to the lens most of the time. I do not notice any significant drop in IQ or autofocus with this combo. There is definitely a drop in IQ with the 2x though. It is still useable at closer range though. I am leaning more towards ditching the 2x and just using the 1.4 and cropping where necessary but then I have the Z8 and 45mp to play with. The z6iii doesn't really have that option.

I had the 180-600 and it's image quality was stellar for it's price, easily on par with or maybe even exceeding the 400 +1.4tc but it is very heavy and wasn't light enough (for me) to use as a walkabout lens so I swapped to the 400 4.5. I love the lightweight of the 400.

The reality is that the correct lens for me would probably be the 600mm pf as I rarely shoot at 400mm but it is way out of my price range even second hand and it frankly doesn't represent a big enough benefit to warrant the huge leap in price. I think Nikon set their price way too high on this one.
Trust me the 600pf is worth the money. You really won't know until you use one. Do what I did , rent one for a weekend... You will understand. That's said , the other choices you noted are also excellent (you can't go wrong ). Nikon makes a telephoto for everyone:)

I have the 400mm f/4.5, the 500mm PF, the 600mm PF and an 800mm PF (I know crazy). Personally, I am still not sure where the 600mm fits in, I use the 400mm more than the 600mm and more likely to take it when traveling. For me, the flexibility of the 400mm outweighs any slight advantage the 600mm has in sharpness. If I was forced to sell one tomorrow, it would be the 600mm.
PS. We (mostly my wife) still uses the D500 and 500mm PF (and sometimes I do as well), hence the reason we can't let the 500mm PF go.
PPS. To elaborate a bit more, I have an upcoming trip (and like my prior trip) will take the 800mm. The 400mm is the perfect complement to that. And if I go for a walk and think it will be dark by the time I get back, take the 400mm with the 1.4 TC as I start out and remove the TC when it gets dark. Like yesterday had the 400mm f/4.5 for the burrowing owl at the end of my walk:
PPPS. Another time when the low light ability of the 400mm f/4.5 helped me:

I guess it and depends on subjects you shoot and how close you can get. 400mm is too short for me 90% of the time .. 600mm is my sweet spot. I rarely need 800mm so the 1.4tc on the 600pf works perfectly as needed. When I need the range up to 400mm, I carry the Z 100-400 S which fills that gap perfectly. A very light and versatile kit for me. I would never sell my 600pf. YMMV

Yep that is the logic that justified my most recent purchase, the 600mm PF. Definitely have found it useful, for example when I go out after the sun is up and plan to return before dark. So will use it, especially when I am walking and can't/don't want to carry the 800mm. However when I am shooting near the car and don't have to walk that far, the 800mm PF is my preferred lens. For some subjects (ie. almost any nest up in a tree, hummingbird nests, etc where one doesn't want to disturb things) the 800mm which I often use with the 1.4TC is perfect. So don't plan to sell any of my lenses (as I said, if I was forced to sell one, but don't see that happening).

I often shoot at 600mm, but I find the 400 4.5, combined with my wife’s z50ii body, a great combination. Makes for a nice ‘600mm’ setup, and I can go up to 840mm with the 1.4TC at f/6.3 so a decent all-rounder.

I suspect I will let the missus inherit the 400 4.5, and invest in a 400 2.8. So swapping bodies between the z8/z9 and the z50ii, combined with it and the 1.4TC, will give me all FL’s I am after. Below a quick shot this morning of the 400 4.5 /z50ii combo.wide-open, it can be sharper if we stop down 1 stop.

There is no question that if you want to cover all the bases as cost effectively as possible the 180-600 can't be beat. It's the Z version of the 200-500 as far as incredible IQ for the price. The differences in IQ compared to higher cost primes is more noticeable in BG treatment than with sharpness.

For those of us who aren't doing this for a living the questions we each have to answer for ourselves are about priorities based on how/what we shoot. IQ, cost, size/weight, supported vs handheld, etc. One thing I've realized over the years is that trying to cover all the bases so that we never miss a shot is a wild goose chase(no pun intended). Let's face it we all miss(or ruin) a lot more shots due to operator error, poor field craft, slow reflexes, etc, than due to not having the right equipment for the situation. While the arguments about covering focal range and minimum focusing distance are valid they may not be relevant. We each have to make that determination.

Specifically regarding options for 600mm (actual FL, no crop factor) my own experience is that I find myself opting for carrying either the 400 4.5 and TC or the 600PF. Carrying the size/weight of the zoom 100 percent of the time to cover 10 percent of the opportunities just isn't worth it to me. There are some situations when it makes sense. But my point is that between those three options IQ is close enough that it's not what drives the decision. Enjoying my time in the field does.

You kind of nailed what I was thinking about last night, Dan. As is all of photography, lots of tradeoffs. I think that we all want to see if we can "bend the curve a bit in our favor, but that only works to a small degree, if at all. I keep going back and forth on what is most important, what I can afford, and what I would enjoy using. I have seen great examples of almost all the lens combinations, and I know that in the hands of a talented photographer, I am sure good images can be had at all focal lengths, if one "can see" (borrowing from Ernst Haas). I greatly appreciate the skill required to get that close-up of a bird in action, but that is only one type of image. I think another night or two of sleeping on it and I may have a decision.

Well, for better or for worse, I made a decision and made a purchase today before the rebates end this weekend. After long and careful consideration, I decided to go with the 100-400. The 400/4.5 was a dream lens in terms of size, performance, and IQ, but it was difficult focal length to use for a lot of what and how I like to shoot. The 180-600 offered me additional focal length and a lot of improvements over the 200-500, but its size was not ideal for me. I wanted focal length range, a lens that I could use hand held and that could fit into a pack or should bag, and the 100-400 seemed to fit that description. I know that there are better lenses at 400mm for IQ and that I am a bit shy of what I ideally need for BIF, but BIF is only a part of what I like to shoot, so I will have to think about how to approach and address this issue. But I am think it is the right decision, although my wallet might disagree. I hope the 400/4.5 goes to a happy user as it looked almost brand new and performed quite well.

I’m confused. Why not the 400 f4.5?

Oh I see. That makes sense!
 
And the 400 4.5 on the 24MP Zf body, still pretty decent and capable, even if it doesn’t have a dedicated Bird-detect mode. Not as good as the Z50II in that sense, but still able to capture decent shots. Straight 400, sans TC in this instance.

I have the Z 400/4.5 and Z 1.4TC and like the combo very much. I think next step would be the 800 PF or some of the F-mount FL ED teles with good price.
I can't say that there would much penalty regarding the AF speed. If anything the image is more magnified (from the same distance) which may help with subject detection. VR performance takes propably more hit with the TC, so faster shutter speeds are needed.
At 560mm/f6.3 it also has much shorter MFD of 2.5m vs 4m with the 600 PF, and have achieved some nice closeup photos with the combo. While the 600 PF is certainly sharper according to reviews, I think 400/4.5 is more versatile option especially for other uses besides wildlife.
 
I think Andy said it best. I’d opt for the 600 and add the TC if you feel you need more reach (which you will😀). The 600 is about $1K more expensive but the TC is $550 so the money difference is minor. On the plus side, the 400 is a half stop faster, weighs a half pound less and is 1” shorter. None of these would be enough to make me go for the shorter focal length.
As far as the TC14 image degradation nonsense is concerned, unless you are making billboard size prints you will most likely never notice any difference in IQ when using the TC14.
 
I did not read through three pages of comments so this may have been mentioned. That is the MFD between the 400 F4.5 +TC and 600 F6.3. Usually on my morning walks I take the 400 +TC 1.4. This morning I took the 600 f6.3, why I’m not sure. Its the dog days for birding here, but I did come across some Verdin, and Song Sparrows building their nests. I could have gotten some shots, nothing great but fun to shoot. Only the 6.3 (13ft VS 8ft) would not focus close enough. So I ended up just enjoying the show which isn’t all that bad.
 
@Replytoken : Have you decided on your lens yet? 400 4.5 is plenty sharp, at least imho. I recently got the 600 6.3 as well, and both are superb IQ, light-weight lenses. Sharp enough, unless you're shooting for Discovery Channel, I would imagine :)

This is the first that I can recall of anybody mentioning this. One of the things I found frustrating about the 200-500 was its slow speed in acquiring focus. It drove me crazy, especially when I compare it to some of the faster lenses I have used over the years. I suspect the 400/4.5 w/1.4TC will still be faster, but it is doo to know this can be an issue.

Thanks,

--Ken
I don't notice any slowing of AF with the Z1.4TC on the 400 mm f4.5 lens. I think that combo is a great bird/wildlife choice. The field of view is narrower the longer the focal length making it more difficult to find a target which may lower the keep rate, but AF spend is not an issue.

While I thought the 400mm/4.5 was an awesome lens, I decided to go with the 100-400, and so far I have been pleased with it. I am still looking for additional reach, possibly through a Z50ii or a 500PF (with the D500), but have not made any decision yet.

I recently grabbed the z50ii for my Wife, and it goes great with the 100-400 and 400 4.5. Very good quality photos from that old D500 DX sensor.

Glad to hear, I looked at one today and am trying to decide on it, and if I do, if I should trade in my D500 as well. Had a love hate relationship with the D500, but much of that could have been the 200-500 that I primarily used with it for BIF.

That said, the 400 f4.5 is plenty sharp on its own, and does well with the 1.4TC.

Must be lens variation, because I found just the opposite in my own experience. The 400 f/4.5 (with and without TC) was hands down sharper than the 500pf.
