Sony 300GM

If you would like to post, you'll need to register. Note that if you have a BCG store account, you'll need a new, separate account here (we keep the two sites separate for security purposes).

I've put some serious thought to doing that. During my first few months with the 300, my summer subjects suited the lens perfectly. I literally didn't touch the 600 for 2-3 months. If those type of summer conditions and subjects were the norm year round I'd sell the 600. But I told myself I was probably getting ahead of myself and would need to go through the winter first to see if the 600GM creeped back out of the closet. Well it certainly has, been using it more 50/50 with the 300GM. That is mostly due to the light levels and somewhat due to the subjects.
So everyone will need to make such a decision on their own based on their own subjects, light levels and tolerance for the heavier lens. Do you need f/4 at 600mm? Do you need 840mm or even 1200mm?
There is no doubt I much more enjoy being out shooting with the lighter/smaller 300GM. Just like I've always enjoyed my smaller lenses over the years like EF300II, EF400DOII, 500PF, Z400/4.5.
I've never been a huge fan of TCs on the other Sony lenses. The only lens I'd been happy with the 2xTC was the 70-200II (borrowed briefly from a friend). The 300GM is the only other lens that it works well on. It is terrible on the 400GM and mediocre on the 600GM (IMO, YMMV).

So I'm keeping the 600GM. But I can certainly see people being very happy just using the 300GM and TCs.
In Europe you certainly do need a longer focal length.
And to my suprise I find 2x TC work really well with 600. And I am picky with sharpness. For instance I have never accepted 1.4 on 200-600 - mounted on a9. To my suprise if light is good (so not really low but also not super bright, as I also do not accept shadows in pictures) the 600 with 2x TC works really well.
 
I sold my 600GM and use the 300 with 1.4/2.0 converters. Image quality is great , very compact and easy to travel with especially as I travel a lot by plane. Also (I have said this many times on this forum) in Europe a lot of bird/wildlife photographers work from hides so a 600 is totally useless due to close distance to subjects. unlike in the States where often the 600 is used with a 1.4/2.0 converter as most photographers don’t work from hides.

Without reliable statistics I'm hesitant to say what most of my peers do but here in the States I'll use a blind (hide) with wary subjects at whatever distance they'll tolerate. The 300 is handy for those occasions when a tiny bird is closer than the 600's MFD but I'll use the 600 in a blind when appropriate. The blind allows me to observe over an extended period of time without influencing behavior.

For tiny birds the 300's MFD often makes this lens the better choice but the blind can block a portion of the light.

I use the 300 + 2xTC when exploring on foot. I use the 600 when I've found a good location and the MFD isn't a problem, blind or no blind.

I didn’t state it properly. I was referring to commercial blinds of which there are many over here, especially in Spain. Birds generally get very close making a 600mm totally useless. As far as I know (and I stand corrected) there are hardly any commercially operated blind locations in the united states. Nice images by the way
 
So I joined the Sony Pro program a few weeks ago for the included benefits, One of which being evaluation loans of equipment. I took delivery of the 300GM yesterday with a 2X TC. I only got to take it out for about an hour yesterday evening. First impressions is, it's so small, lightweight and just a pleasure to use. Unfortunately we're having heavy rain so I decided to set up some exotic subjects inside my home today to do some IQ testing. These are done with the 600f/4, 200-600,100-400 and obviously the 300GM. These are taken at 62 feet from our entry door to the back of the living room on a tripod using a remote shutter. This honestly seems like splitting hairs with some of the results just about being impossible to decide which is best. I hope to be able to get out for more real world experience but from what I am seeing so far, The 600GM could possibly be finding a new home depending on how this goes.

What is the length of the loan that Sony allows in the Pro program? Thank you!

This one was seven days some of the products are 14 days. It just depends on the demand and supply they have on hand. It’s a pretty nice program to be honest. I would imagine it would cost three to $500 to rent this lens for a week.

You do have to give a 14 day leeway. I actually got mine in about 10 days but even if you get it early, the time starts on the day you originally set up so in my case I get mine for 11 days which is nice.
 
Another thing about this lens that absolutely blows my mind is, it is quicker to focus with a 2X converter than my bare 600 GM and that is an empirical fact! I truly have never tested a lens that accepts teleconverters the way this does in my opinion the 600 GM suffers even with the 1.4 to some degree and it’s pretty terrible with the 2X or at least in my opinion this lens is just a real piece of work.

Here are a couple of commercially-operated blinds in the US, just off the top of my head.



in parts of south Florida a blind isn't necessary, I've used a 90mm lens for some photos. There are also several blinds at National Wildlife Refuges and other public lands, some available by reservation, some first-come, first serve.

 
Dont forget that you are still on the "honeymoon" with the 300GM ;) Give it some more time before you get rid of the 600GM.
Oh, I definitely will. I’m not going to make any hasty decisions, but I am absolutely astonished with how well this lens performs with teleconverters and what a joy it is to carry around as opposed to the 600.
 
It will definitely be a solution for many folks, especially if physical issues demand smaller and lighter. And of course, if 300 is a commonly used focal length for one’s shooting. If a 2x TC is going to be permanently parked on it however, an entire stop of light (versus 600 f4) is big deal.

Considering how successful the 600 f:6.3pf from Nikon is, there is a significant portion of photographers who favor lower weight over 1 extra stop of light - compared to Nikon, the Sony solution is more expensive but you can look at it as a 600mm f:5.6 that can also be a 420mm f;4 and a 300mm f:2.8 for 50% more cost. it won’t fit everybody but I certainly see the appeal - so much so that I am also planning on living with both for a few months and decide what suits me best. It took me over 30 years of photography to buy my first 600 f:4 so I’m not going to let it go easily ;) but size and weight of that 300mm option are very tempting.

Same boat I’m in. Took me many years to get the 600GM but man this 300 is just great to go out with, especially hiking. Never ever would have believed a 2X tc would perform this well with a lens.

Do you find yourself going out more with the 300 after buying it?

Agree on all fronts. As always, it comes down to personal needs and preferences. For me for example, it’s not just the stop loss at 600, I also shoot with the 1.4x on my 600 about 35% of the time, which is a fair amount. That automatically takes the 300 out of a play as a complete solution for me. Again, I agree with all that’s been said. I’ll probably pick it up to use as a compliment to my 600, not a replacement. I do love the idea of hiking with it for mammals (and popping on the 1.4x for a 420 f4 option if needed).

Cheers!

That's how I see it.

I wanted hiking-friendly 600mm and 300mm lenses; with the 300 GM +2x TC I get both for less weight than the 600 PF + 300 PF + FTZ. Add a 1.4x TC for a bonus 420 mm f/4, and it's still less weight than the two PF lenses + FTZ. Also the Sony a1 weighs less than the Nikon z8. At f/2.8, f/4 and f/5.6 the 300 GM + both TCs also has faster maximum apertures than a Nikon 300 PF / 400 f/4.5 / 600 PF option. For MFD only the 300 PF bests the 300 GM.

Purchase is planned for early next year - I rented it once and loved it but I need some quality time to decide. Right now my free time is consumed by helping my 80 year old father battle colon cancer, chemo and surgeries… but once we are on the other side of it, I’ll be back outside :)

Really sorry to hear about your father. I’m sure that’s beyond difficult to deal with. I wish I had more time with the loaner that I have right now but unfortunately, I have to send it back in a couple days. I really would like to have it, but I’m just not sure if I want it in conjunction with the 600 F4 I feel like if I had both I would more than likely grab this more often which would make me feel bad about leaving a $13,000 lens sitting in a cabinet lol

I ran the exact same math and came to the same conclusion 😁 the question that remains for me is whether I also need a less-hiking friendly 600mm as well. Although I have to say, the Sony 600 f:4 is about as portable as it gets but in hills and mountains, I’m starting to feel the weight.

I agree, that’s the dilemma.
 
I agree, that’s the dilemma.
I still have the 200 600 so in my case if I ever needed to go beyond 600 I could always put the 1.4 on it. I mean it’s decent image quality but definitely not as good as the 600 F4 I think with these smaller lenses getting better, especially with teleconverters that a lot of folks are going to rethink buying the large F4 primes to be honest
 
One of the things that’s really sweet about this lens. Is it size and weight whenever you’re waiting for something to leave the nest or a situation similar to that also how well the focus ring is placed on the lens is just so easy to get to everything it’s probably one of the tougher decisions I’ve had to make as far as photography gear And wish I knew the right answer lol

Same dilemma for myself. For several months I used nothing but the 300 but have gradually begun using the 600 again, almost entirely where a tripod is most beneficial.

When using the tripod I like having a second camera handy for the unexpected things that happen to the side or behind me; in this case the camera on the tripod doesn't have sufficient mobility so I keep the 300 (with or without TC) ready on the second body, hand-held.
