I just spent way too much money on a Pentax M42/K adapter so that I could finally have that elusive infinity focus on my old screw mount lenses when I use them with my K100D. But now SR is deactivated when an M42 lens is attached, I presume because the lenses don't touch the row of metal contacts on the mounting plate of the camera body. I guess the camera doesn't know there is a lens attached at all.
Have others experienced this? If so, is there a work-around for it so that I can get SR working again? I hate to think that if I want that feature I have to use the el cheapo adapter with the big flange, since it works with SR.
Below are a couple of photos to show what I'm talking about. The pictured body is a ZX-M, because I needed to take the pics with the K100D.
