I've seen some new Q users complained about that the SR of P-Q was disabled when using manual lenses via adaptors..In fact, this has been already stated and well documented in the user manual (Page 97, the last footnote of the Item #4 about SR function). So, what is the fuss about? :-)Related:-Kipon C-mount and D-mount Adaptors to Pentax Q-mountPentax Succeeded to Adapt ALL Lenses and Mounts on
