I Use a 645Z with several lenses. i am quite interested in the new pentax K1 as an "emergengy" and light body. it's possible to use the 645 lenses on the K1 keeping AF and auto aperture?

i own the 55 and 25F4 without mechanical aperture ring on the lens, and other older FA lenses with the mechanical ring

thanks!

There have been some rumors of a forthcoming AF adapter,but nothing substantiated yet. The existing OEM one is all manual and doesn't support auto aperture. I haven't looked in a while, but there might be 3rd party ones that add a manual aperture ring.

I do not know why this feature has not been publicized. There have been references on PF to the use of 645Z lenses with a special adapter allowing further resolution enhancements. Let's wait and see. Perhaps that is the next surprise from Ricoh. I also have a few 645 lenses and would love to use them on K1 and get more out of the camera. If true, this feature would be exclusive to Pentax for sometime to come as no other manufacturer has both DSLR and 645 line of bodies and lenses for this kind of integration.
