The Pentax 645 system is the perfect entry to medium format. The 645N II is an intuitively easy camera to operate. One read of the manual and you're good to go. Although a heavy camera  the well designed body makes hand holding a breeze.   It is a very well built robust camera, made for work. Uses 6AA penlight batteries and is very frugal with these. Superb range of manual and auto focus lenses, all of good character, to cover any photographic purpose. This example is in perfect, almost unused condition and comes with body cap, 1x120 film back and shoulder strap. Highly recommended. Lens options available.
