I'd say mostly your panning. I don't get them all teh time either :-)

I don't use continuos focus either. Hate it with a passion

I have been going through the pictures that I took at the Duxford airshow,
and am struck by how many of the airborne shots came out fuzzy.

It looks as though I have a focus problem. I am using centre weighted
continuous focus which means that it is possible to take a picture even
when the autofocus has not achieved proper focus. The advantage is that
there is no delay between pressing the shutter release and making the
exposure. I have noticed that when I use burst mode, a fast moving
aircraft does not stay in the same relative position in the frame in each
exposure. Could it be that the autofocus temporarily focuses on a patch of
sky rather than on the aircraft?

I know the camera and 70-300VR lens that I use are capable of taking sharp
pictures, so the problem must be in my technique. Do I need to practice
panning more?

I would appreciate having the experts weigh in on the subject.

Thanks in advance,

Indrek Aavisto
