I just received my "Walimex" 500mm f6.3 lens. It is gorgeous. However, with the "K" mount ring for Pentax, my "SR" does not function. This applies to my K10D's and K20D's. I was under the impression that a message would come up to choose focal length and off you go. Am I missing something here? It does work in Aperture, TVA and Manual priority obviously, but that greatly needed "SR" does not show as functioning...
Is there a screw on adapter that will allow for the recognition of AF etc and especially "SR". My 50mm f2.0 lens is recognized with the Pentax mount.
Thanks
Ben
