Build your own camera for $35! It’s not digital, but that’s the point. It’s an actual SLR with a detachable lens! The aperture is fixed (50mm f10) and the shutter speed is fixed (1/80s – or bulb) and it shouldn’t take more than an hour or so to put together. Focus is from 0.5m to infinity.
How long before someone put s a digital sensor in one I wonder…
