The owner at my local watering hole today just gave me this older Minolta XG-M heavy silver body camera and lens, said something is maybe broken on it and i can have it, it is a 35MM Manual SLR. It has a battery in it, though i do not no how Old it is, all the dials on top work, ASA, shutter speed Etc, every thing on the lens works, it opens and closes when you move the Preset Aerture Ring on the lens. The only thing is when you look thur the Veiwfinder, Yes the lens cap is removed, all you see is Solid Black when you move the Aperture Ring it still is Solid Black. Do you need a fresh new battery for this to work? The lens is a minolta 50mm 1.2 with a 0 and a slash thur the zero=49mm Here are some serial #'s. On top of the passed is # JC11 1 5. on the bottom is JMDC On where you mtg the flash is the # 2285746. Hope all of this helps you out, if you need any more information let me no. And the film door closes nice and tight. Mike.
