You dont get any AE with non "A" or later lenses. Manual only. You have to take a stop down meter reading/shutter setting every time your lighting or aperture setting changes....Its not very good if you need to shoot fast under a lot of varied lighting condtions. (actully you can get AE with these lenses but only if you use the maximum wide open lens aperture setting). jco

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 -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
