I wonder if any bright sparks have some advice for me.
I shoot my son's football matches and also any tennis tournaments I'm lucky to attend [e.g. Wimbledon] with my D300 and venerable one touch 80-200 f/2.8 lens.
I had the body set for focus priority in the past and found that it wouldn't shoot sometimes, clearly not having achieved focus, so swapped to release priority. As a result I get a minority of shots that are not tack sharp. I'm not talking full-on blurry shots and neither does it appear to have focussed incorrectly on something in the foreground or background. Essentially sometimes [and I don't know why] the lens fails to find focus leaving everything just slightly soft.
I had the lens serviced by Nikon last year and that has made no difference to the behaviour. The 80-200 is somewhat prone to back focussing but I have corrected this using -13 AF adjust.
My other settings are continuous focus, AF back button, AF lock on normal and generally use a single AF point somewhere around the centre. I've tried using 9, 21 or 51 3D focus tracking with similar results.
I suspect my ancient lens isn't helping, but I find it strange that most of the time it performs fine but sometimes doesn't and I can't stretch to a 70-200 VR so I was wondering if there was something else I may have overlooked.
Any bright ideas?
