I have a D7000. I’ve taken thousands of shots with it, and have been basically happy. It’s only when I need to have sharp focus that I’ve been unhappy.
For one thing, I can’t manually focus the thing for beans. For another thing, seemingly it can’t auto-focus sharply for beans either. Well, at least with my 18-200mm lens.
I have spent hours playing with various ways to do AF fine tuning. Nothing really helped.
Until I read something. Last night I tried, but failed to get a sharp, manual, focus on the half moon. Couldn’t do it, and so I started searching around for info. Turns out the moon is pretty challenging to photograph, but one piece of advice stuck out. —-Remove the UV filter—- Gasp! Dare I?
So today I did it again… played around with AF Fine tune, failed, but then took the UV filter off, and turned off AF Fine tune… Uhm.. It worked.
Well I was able to take these shots, which you may not agree are in focus, but for me, they are in the best focus I’ve gotten for these subjects. Zoom to 100% and they look fine… zoom a little further, and still ok… So that makes me happy. I’m done with AF fine tune.
