Can you post some pictures of your test?
I was really just trying out the mechanical aspect, wasn't thinking about the images. Had it in manual and ignored the shutter and aperture settings, so the pics are very dark, dark enough to not be of use.
I'll do some more controlled tests in the next few days, but my initial impression is that the new firmware had no effect on the autofocus. Didn't seem to cause any harm.
BTW, lens was a Tamron 28-75 2.8 XR Di LD, which I like a lot, both as a performer and for its results.
