Hmmm .... getting "correctly focused images pretty much all the time" doesn't sound so good. Getting correctly focused images all the time sounds a lot better. Can't help but wonder how much of a role DOF plays in your correctly focused images. I'd be interested to know how well the focus looks at wider apertures, like 2.0. That would seem to be a better indication of how well the camera is focusing. Just ca;ll me an old fashioned skeptic ;-))
