The 645 is a medium format film camera by Pentax. Thanks to a forward thinking high tech design it's noticeably more compact and lighter than competing contemporary medium format SLRs. The large checkered handgrip houses six AA batteries that power the entire camera including an integral motor drive. With the conveniences of excellent balance and handling, autoexposure options, and TTL flash control, and auto advance, using the Pentax feels a lot like using a 35mm SLR.
Originally introduced by Pentax in 1984 the 645 proved very popular as the camera offering the advantages of medium format's much larger negatives without the bulk and hassel traditionally associated with moving to medium format. In 1997 Pentax released a successor the 645n which keeps the same successful form factor while adding autofocus capability, multiple metering patterns, and updated controls. The original 645 remains an excellent value. Paired up with high quality Pentax professional lenses the 645 still offers the clarity and pop that draws the most discerning photographers to medium format.
