Originally posted by Lowell Goudge I think you are being too hard on both yourself and your kit.
You simply cannot to make an 8x10 out of a shot where you will only use about 5% of the total image.
a better lens, higher resolution camera, and even ideal conditions simply make life easier but won't give you, at the shooting distance much better results.
As a long time bird photographer, I can tell you that there are times when you have to accept this is all you will get, a shot useable for identification.
I think you should take a different approach, accept this will never be other than a snapshot, and keep the bird on you list of need a better shot.
Sage advice, Lowell. Thank you, you turned a light on for me. After reading that I feel much better about the lens. I've only recently got it and doubtless need to spend much more time with it. And you're right, the conditions were pretty ordinary and the shot was never going to give me a pin-sharp close-up from that distance. Sometimes you need other people to point out the bleeding obvious!
Thanks, DuckysDoll. Why did you reverse the shot, out of interest? I know ducks fly backwards but I've never seen a curlew do it...
