Welcome to the wonderful world of auto-focus! With all the hype and
hoopla about it, you would really expect it to work, but the little
secret, known to those of us who own camera bodies with sharp VF
optics, is that AF is not accurate enough for really precise focus. (Some maker's cameras have such poor finders that not only can one
not check for the AF errors on the viewing screen, but one is forced
to use the AF because the screen is unuseable for manual focus!)
Hope This Helps
