A basic, all-manual SLR combination for students, the Vivitar V3800N 35mm SLR Camera with 28-70mm Lens will help you learn the art of photography the old fashioned way. Load, advance, and rewind the film yourself. Determine exposure manually with just a simple match diode centerweighted meter, and enter the settings on the aperture ring and shutter speed dial. It can use any Pentax K-mount lens which has an aperture ring. You'll only need small, long-lasting button batteries for the meter (the shutter is all-mechanical) and some film. The V800N is a basic camera that's a great teaching instrument and fun, too.
Though the V3800N shares many traits with other student cameras from other makers, it does have a few advantages. You can make multiple exposures on a single frame with the V3800N, there's a self timer as well, and a depth of field preview allows you to see the actual range of sharpness in an image before making the exposure.
