I have no experience with the A7RII but I believe it's not as good as the A7RIII and the A7RIII is nowhere near as good as the A9. However, you can still get excellent results you'll just get a lot less keepers especially with tracking BIF's. I'd like to see Sony release a 150-600 f/5.6 as I'd rather stick to f/5.6 than f/8 on the A7RIII. I believe the A7RIII works a lot better with adapted lenses too than the A7RII
Have you considered a Nikon D500, because that is noticeably better than the A7RIII and has even more reach than the A7RIII when FL limited. The D500 + 200-500 combo is pretty damn effective and can be found for similar money to the A7RIII alone. D500 is a lot more consistent than the 7DII for tracking and has a better sensor. You need to step up to the A9 if you want the very best in AF and it'll work faster with adapted lenses using MC-11 than the A7RIII....Show more →
Thanks and yes, I did consider the Nikon D500, also the 500PF, and the 100-400GM (already owning a Sony A7rII).
But my background is, coming from a Pentax DA560mm f5.6 and 1.4TC, I wanted to replicate that package in a (much) smaller size and lower weight and with better AF. The 400DOII with both extenders adds a very fast 400mm f4 to that package for BIF. But I hardly ever did BIF with the Pentax set-up (nearly impossible). My priority is wading birds, water fowl and overall distant birds (living in Western Europe, where birds have been intensively hunted for as long as one can go back unfortunately, and are immensly shy).
The Canon 7DII is nicely fast, but rather unreliable AF in certain types of light, and coming from Sony sensors, rather limited sensor wise. I got it very cheaply in the Canon lens/body bundle, so can easily sell it without loss. But my current plan is to practice BIF with it, and add the Sony 42mp for IQ.
It may sound strange, but for wading birds, waterfowl, I was pleasantly surprised with the AF from the 400DOII+1.4TC on the A7rII. I had expected nothing really, but accuracy and responsiveness are well above expectation, even without solid practice. The electronic front curtain shutter also helps a lot at slower shutter speeds in lower light, with the very, very good Canon IS helping out for rather static or slow moving birds. It's a nice set-up for handheld shooting. Only important thing is to set the focus limiter, otherwise the lens will travel all the way back to limit, and forth to the point of focus again, which takes too much time.
Still, a small bird may fly by and the AF then has to be responsive and decisive. So for that, and also for enabling all the focus modes, I was wondering if the A7rIII makes a big difference.
Regarding the A9, I would lose too much reach, and if I want to go to a high performing allround body, I would perhaps do well waiting for a future EOS-R with decent sensor and updated AF.
In short: if the Sony A7rIII is a significant upgrade for adapted Canon lenses, then I will trade my A7rII in.
