Not a very high percentage of keepers today - just not enough light, and too much subject movement, but I did manage to glean a few good shots...
I tried the same subject today with my Sony A7R IVa. Out of 28 frames, this was the only keeper - and viewed at 100% it is a tiny bit OOF on the birds eye, but certainly good enough for web posting. That's less than a 4% success rate...
Sony's stabilization is a joke compared to Olympus. At those slow shutter speeds I am not surprised. On top of that, my A7r IV wont focus accurately with the 200-600 no matter what the shutter speed. Some people have this problem while others have no issue at all. This leads to some arguments on the Sony forum. I spent a lot of time trying to trouble shoot the issue but finally gave up. I am not surprised at all by those results given the slow SS and known issues with that combo.
I've gotten some excellent hummingbird shots with the A7R IV and 200-600 but naturally it helps if there's more light; more importantly, since it doesn't have bird eye AF, it's critical to get the active AF point over the bird's eye. When you are so close to such a small subject, the DOF is almost zero, so there's no margin for error, and I don't keep any shots where the bird's eye is not in sharp focus. The A1 does much better, as does the A7 IV.
Well, your one up on me. I could never get that combo to work properly, which is why I bought the 600GM. My A7rIV works perfectly with that and all I had to do was spend the amount of money I would on a cheap car to get there.
Here's one from a couple of minutes ago with the A7R IVa. I bumped the ISO up to 6400, and used the small flexible spot AF and placed it on his eye, and still had a number of soft images, but when the AF hits, the results are pretty nice.
