Is anyone having problems with the autofocus on their D7000? On several occasions I noticed my lenses would not AF at all and I couldn't figure out why. After fiddling around with the settings and changing lenses, I noticed there is some play/slack after the lens is locked in place. I finally discovered that if I twist the lens clockwise after locking it in place the AF seems to work fine. I'm talking about twisting it just a hair.
I have four lenses and they all have exhibited the same condition on the D7000. So I check them out on my D70 and they have some play as well, but I've never had any issues with the Autofocus.
Has anyone experienced this?
