Fujica AX-3 with 50mm 1.9 in VG condition. Well made SLR from the 80s with manual and aperture preferred auto exposure. Lens in very good condition with no haze or fungus. No cap, but does have a filter for protection. Uses commonly available 6v battery (like the Canon AE-1). I just film tested this; my results suggested about 1/2 stop overexposed in auto mode. Good student camera.
Other lenses aren't very common, but Tamron adapters available cheap on ebay.
