I just purchased this lens and the Pentax adaptor for my 645D. The lens and adaptor are in Excellent condition. I can't figure out 2 things with this lens
1- On the lens is a auto. Manual ring and I tried to move it to the Right towards the auto side, It will move when I push it but comes back to the Manual side
How does this lens work? I know its Manual Focus.
2- I dont se an f stop ( aperture number in the Top LCD. I move the aperture ring but NO number shows up showing me my F stop settings.
Thank you, Dennis
