Pentax K1000 35mm (Cleaned & Tested with minor wear and tear.)
The Pentax K1000 is one of photography's greatest, most popular and longest-lived cameras. Equipped with a 50mm f2 lens.
The Pentax K1000 is simple. It does exactly what it needs to do, and nothing more.
The Pentax K1000 is a 35mm SLR. It is completely mechanical and needs no battery to run, except for one tiny 20¢ A76 cell to run its light meter.
Unlike the "automated" digital nonsense with which too many people burden themselves, the K1000 has only three shooting controls: aperture, shutter speed and focus. (You also set the film speed when you load it.)
There is a very good reason every photo teacher demanded the K1000 be used in their classes: because the K1000 is an extraordinary camera that forces you to think about your picture instead of your camera.
