Pentax 645Z Digital Medium Format Gear Guide

Simply put, a medium format camera has a larger sensor than other standard DSLR cameras. A bigger sensor means bigger pixel size, which means better quality. The Pentax 645Z has 3-4x more frame surface than sensors equipped on Canon Rebel DSLRs, which means stills taken with the Pentax can be enlarged significantly without losing quality.

Medium format cameras also have no perspective distortion - images taken more closely resemble the way the human eye sees the real world. The field of field is much wider than other cameras with standard cropped sensors. Let's say you're shooting on a 6x7 medium format camera with a 50mm lens. If you compare your images to a 35mm camera (also with a 50mm lens), the field of view will be different. The medium format pictures will actually see what a 24mm lens on a 35mm camera would see. Simply put: the larger the format, the wider angle your lenses become. You can shoot a wide scene but it will have the "real-world" look of a lens with a longer focal length. The subject remains proportional and not "stretched-out".
