Hi, I have a Pentax DS, and I'm thinking of buying a used manual focus 28mm lens for it. I already have a 50mm f2.0 manual focus lens and I like the image quality and fast maximum aperture quite a lot.
My 50mm f2.0 lens has an "A" setting on the aperture ring. I leave the lens set on this, and adjust aperture on the camera body. I like it just fine that way. However, I've noticed that some of the used 28mm lenses I've seen have an "A" setting on their aperture rings and some don't. What would be the disadvantage, for a DS user, to not having the "A" setting on the aperture ring? I assume that shutter-priority and program-mode auto exposure would be out of the question. Is there anything else I should know about? Would I have to use "stop-down" metering with such an lens? thanks, Glen -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
