To the OP: most college courses that teach film shooting want you to have a camera that is completely manual, or at least has a manual mode.
Some Pentax cameras, like the ME, have only automatic modes, so be careful. You can download the manual for any Pentax camera, film or digital, from the Pentax USA website at

The classic student camera is the K1000. It is a completely manual camera. You must set the shutter speed and aperture, although the camera's builtin meter will tell you if you have chosen a "correct" combination, but it will not prevent you from using an "incorrect" combination. They're cheap and readily available.
