That is the recommendation. Lens IS OFF, camera IS auto
A few from the backyard. Butterflies are prolific this time of year in Central Texas. I struggle to get the focus point on the head but these seem okay to me.

Interesting as I have found the opposite to be the case with my OM-1 + 150-400mm.

I never turn it off, but I haven't done any empirical testing either above certain shutter speeds. The OM-1 Manual says this with regard to OIS:
S-IS Auto "Image stabilization applies to motion on all axes.
If panning motion is detected, the camera will
automatically suspend image stabilization on that axis."
Same here; I never turn IS off with any of my m4/3 lenses.
When I had the Olympus 100-400, I found I got better results using it on my Panasonic G9 than I did on either of my Olympus bodies.

Very nice hummingbirds. Are these taken with flash? Do they stay all winter? These are great.
Thanks!
These are all natural light (or lack thereof...) and all hand-held. I don't even own a flash any more, although I have been thinking of getting a small unit for macro.
The Anna's Hummingbirds stay here year-round now. When the weather gets cold, it's a challenge to keep them fed; they have become habituated to feeders and garden flowers, so they don't have many other food sources in winter this far north. Right now, the males are spending most of their energy chasing rivals away from the feeders.

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...
Great feather detail, nice backgrounds, cool hummingbirds...what's not to like? Nice.

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...

Is this hummingbird and the ones above cropped?
This one was shot in APS-C crop mode on the A7R IVa; some of the previous ones shot on the OM-1 were cropped slightly for composition. I find that when I'm hand-holding during a sequence of shots I have a hard time keeping the subject in position in the frame, so I have to crop a bit as a result.
It appears to me that the OM-1/150-400 did a significantly better job.
This confirms the opinion expressed on "Backcountry Gallery Forums", a Nikon/Sony forum, that for bird photography the only Sony that is worth getting over the Nikon D-500/D-850 in crop mode is the A1. This opinion was expressed by several Sony shooters. As an aside the conclusion was also that the only Nikon worth getting for bird photography is the Z-9. This was expressed by many Nikon shooters.

I couldn't imagine ever going back to a dinosaur brick like the D850. I've been tempted by the Z9, but Nikon's long lenses don't focus close enough to be practical for small subjects like the hummingbirds in my back yard.
The skies lightened up a bit this afternoon, so I grabbed a few more shots with the OM-1 and 150-400. This one is cropped in about 30%, just enough to centre the bird in the lower portion of the frame.

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.
