The Pentax 645Z is a digital medium format (33x44mm) camera with a 51mp sensor, compatible with any Pentax 645 lens, giving it a huge catalog of manual- and autofocus lenses to choose from. It’s very slightly bulkier than the film-based 645N, but it’s got an excellent grip and a well-thought-out interface that keeps it very usable for handheld shooting. This 645Z is in excellent condition overall, with minor cosmetic wear and approximately 7600 actuations. Includes battery, charger, and strap.
