Focus Repeatability
Dec 5, 2005

Has anybody ever tried to see how repeatable the AF is on a D70?
I tried it today with my 85mm f/1.4, and 17-55mm f/2.8 lenses. I set the
camera up on a tripod, shooting at a stationary object at a distance of
about 10 feet. I fixed the exposure by using M mode, and I manually
de-focused the lens between each shot. I also used the remote to take
the pictures. Out of 10 pictures with the 85mm lens, I saw a slight focus
difference in 1 picture. I had both lenses wide open.

Is there s specification on AF repeatability?
