Hi Jan, I've not been keeping up recently, but assume these were taken with the new'ish x-600m zoom on your Sony?
I'm interested to know the shutter speeds you used and how much you cropped (not much on the seagull it seems)?
I'm sure my results would be no better, but to my eye it seems like the seagull isn't as sharp as the wonderful shot of the cormorants? I'm guessing tracking BIF introduces additional challenges etc.
It would be lovely to hear any other findings from your early use of this combo, ergonomics, balance during a long days shooting etc
The images were indeed taken with the Sony a7IV and 200-600mm lens. The Seagull is uncropped, the first cormorant is a 6K crop from a 7K file and the second was cropped at 5250 pixels by 3500. But somehow I loose a lot of sharpness when exporting these pics from Affinity at 2160 pixels on the long end, I am kind of used to apps which resharpen on export so need to look into that a little more.
That said, the “VR” on the Sony 200-600mm is not as good as the 200-500VR with the D500 which doesn’t help with an even longer lens, the consensus seems to be to switch OSS off for most situations above 1/1000th or so whereas the 200-500VR never gave me blurry images at high speeds and also did a better job at better stabilizing the image at low shutter speeds.
But these are early days, there’s so many more AF options and setups to figure out than on the D500 and some can really ruin the outcome.
