For sure...but the issue is it can't even reliably take a photo of a still bird on a stick or a duck floating by without back focusing most of the time. I don't need it to do challenging BIF (although today the RIV and 600GM was nailing Kestrel's IF so the body ain't terrible) but I do need it to reliably take a perched bird photo
Arbitrage ... I believe you and you have been very helpful in sorting things out. I am not that good at BIF but like to try anyway. I have both the A9II and the A7R4 and for BIF its the A9II all the way. But I would like the A7R4 to work for still images with the 200-600 for some more sedentary. So I gave it a try yesterday with quite a few shots and most came out like these photos, which are cropped quite a bit. They were sho in RAW and just converted to JPG. No sharpening was applied. To my eyes they look pretty good. Maybe I got lucky.
