Im using a d70 w 18-70 and sb600. I have quite a few pictures thats out of focus. Initially i thought its either the camera or lens focusing problem or my own hands shake.
But I realised the OOF pictures are almost always when its super dark surroundings and the sb600's focus assist activated. Ive taken sharp pictures with the lens in brighter environments even at 1/30s shutters and wide open..
Could it be the sb600's assist messing up with the focusing or any other problems? Any explanation on that?
