I have a question that I really hope someone has the answer to.
I bought a Sears 50mm f/1.7 Manual Focus lens for use in my college Photo class. It works really well with my PZ-70 film camera, but I popped it into my *ist DL and the aperture will only stay at 1.7 no matter what I do. I've used older lenses with my DL before, and I know that you have to go into the menu and enable the use of the aperture ring, but no mater what I cannot change the aperture. There is no way to control the aperture from the camera (as I would expect), but turning the aperture ring doesn't do anything either.
I found one of these on eBay if that maybe helps:

Is this a problem with the lens, camera, or is there some sort of incompatibility that I am unaware of?
