The Mamiya 645E is a medium-format SLR camera made in Japan by Mamiya, introduced in March 2000. It makes fifteen 6x4.5 cm images on 120 roll film. This model is a simplified version of other cameras in its series, featuring a fixed metering prism finder with a Keplerian magnifier/dioptric correction eyepiece and a fixed film chamber that uses film inserts like the original M645. The shutter speed dial is located on the left side of the body, and the hot shoe is on top of the prism. The 645E uses the same bayonet lens mount as earlier Mamiya 645 cameras.
