My youngest wants a film SLR. I'd like to spend $50 or less. I'm looking at everything from Mamiya 35mms to A series Cannons or even an older Rebel. Something cheap enough to be disposable that she wouldn't have to stress about. Manual focus is cool. A good meter with a few metering modes; spot or center weighted so she can learn about exposure. Full control over ap and shutter, that sort of thing. Any ideas? Change from the 50 would go toward a tripod.
