20 May 2009 User said:Nice shot but, as you say, lacks sharpness. I don't know your lens and I'm a D40 user so I don't know your camera either, however, looking closely at the image and its EXIF data, I think there may be more than one reason for the lack of sharpness:
1. The lens *looks* as if it's focussed on the neck of the foreground bird. At f/6.3 and 500mm you will have very little depth of field at all, hence the bird's face is slightly out of focus compared with its neck. Notice that the tip of its beak is more out of focus than its eye. So that's problem number 1 - very tight depth of field causing only a small area of the shot to be sharp.
2. Since it appears that the point of focus is on the bird's neck rather than its eye, maybe your autofocus point missed the eye. It's always important to focus on the eye of the subject.
3. The EXIF tells me that you shot it at 1/20 second exposure. Looking at the shot suggests to me that some of the lack of sharpness is due to either very slight camera movement or maybe the birds moved slightly. At 1/20, either of these movements will produce some blurring. Were you using a tripod? Even if you were, at 500mm those little movements can show up (although I confess to be no expert in the use of long lenses, the longest I've used is 200mm).
Those are my suggestions based purely on what I can see in this shot. Do you have the same sharpness problems with other lenses or in other circumstances? If so, maybe others may be able to help as it may be a camera problem rather than technique.
I hope that's helpful.

Two siblings from our "family" of house wrens. Having difficulty getting sharp photos with my D300. Any suggestions/comments welcome!
