That should be sufficient shutter speed Arthur.
As for the aperture, that's pretty good too, although I would go faster (most of my birds are shot wide-open, and to hell with the DOF.
To my mind, the way to shoot birds is manual with auto ISO. Seems like that is what you are doing too? I limit my ISO to the maximum numbered value (IE not going into the "High" section. If I ever do see something truly amazing, I would rather have noise than motion blur, and if the sighting is not all that amazing after all, I can always press the delete button...
I use the manual setting as well, most recently set to 1/3200 sec. and f/7.1. I use auto ISO set in the range of 100-3200, but on a sunny day in Florida, ISO rarely exceeds 1600, even at f/7.1. I chose f/7.1 because I read a review of my lens which indicated that is the sweet spot for sharpness.
Autofocus is normally set to AF-C using 25 autofocus points. If I’m shooting with a cluttered background, I change that to the mode which prioritizes the image in the foreground, the name of which is escaping me at the moment.
If the birds are white or have large white patches, I’ll use no exposure compensation or maybe even as much as -0.7 stops. If the birds are dark feathered, I might use as much as +0.7 stops. I usually use spot metering using the smallest possible spot.
Based on a suggestion from Akira, I am now setting ADL to auto, as it seems to help with detail recovery in darker areas.
I’m certainly no expert, and I can see where there is plenty of room to argue for other settings, but those are the more important ones I use. I have them set up in custom settings bank “B,” for birds. As I learn more, they will undoubtedly change. At present I am considering changing my top ISO to 51,200 based on your argument that I can always press the delete key.
You may have noticed I previously quoted you but did not reply. Actually, I wrote a long reply, but for some unknown reason it did not post, only the quote posted. I had to leave to meet up with a friend to hunt for the swallow tailed kites, so could not correct it before I left. Still no luck on the kites. We saw a few, but they were too far away to photograph, but the post is now corrected.
