I can tell that K-r looks even more gorgeous with DA limited lens. These lenses are too small for the K20D but look just right with the K-r.

For e-dail, I tried rolling from end to end with completely fast and very slow action to compare. The aperture changed to the same value, so I assumed my copy is fine with this issue. The bad thing is I need to -9 AF adjustment for all of my lenses which are perfect with the K-7.

My AF comparison video between Pentax K-7 and K-r with various lenses.
The first lens is DA 70mm limited, then FA 50mm macro, DA 55-300mm and DA* 16-50mm.

thanks for comparison! it was helpful

it seems like kr is by 0.15 faster than k7 if for example k7 needs 1sec to focus, kr needs 0.85sec.

I didn't count actual focus speed timing, but I feel the same! K-r seems to rotate focusing ring faster than K-7, may be due to higher power focusing motor. If it is faster than the K-7, then the K-r must be a huge improvement model over the K-X and Kx00D.

The k-r seemed much quicker focusing that 50mm!
