Plenty of shutter speed...............the reason i asked, is because the images look a little soft around the head area?
Are you using AIservo ? Single or Multi spot for the focus?
Hi Steve, I shoot Nikon, the images were shot with single focus point (center) but using Nikon's Dynamic Area (if the subject moves other focus points become active), also using Nikons AF-A mode (which adjusts to whether the subject is still or moving). If the subject is still it uses single focus, if the subject is moving it uses continuous focus tracking the subject. I hope this answers your question. I appreciate the help.
Excellent catch, well done.
It's only the last one which looks fractionally soft in places to me. The feet seem much sharper so I suspect that is just a case of having to use a fairly wide aperture which has reduced the sharp focus depth. And without sufficient time to refocus on it's head; which would have been virtually impossible.
Long birds like this will always be difficult to get everything in perfect focus.
But you did well to get that take off shot at all, Joe, and the others are excellent.
Thanks Geoff, you are correct in all that you wrote. The focus is sharper on the feet most likely because that is where I was focusing on the bird before it lept forward in flight. If the bird moves directly sideways all is well but if the bird stretches out and flies away from me then depth of field becomes a problem with a long bird. I concentrate more on shutter speed than aperature for birds in flight, some are keepers and some go into the bin. Thanks for viewing and commenting.
