Many of the features of the 645 AF are retained from Mamiya's previous series of 4.5x6cm SLR cameras (the M645 Super and related models). However, the camera is not built in the modular way that those cameras were; the power film winder is built-in, as is the AE prism viewfinder; a waist-level finder cannot be used (although there is a right-angle eyepiece attachment).
The standard lens is an 80 mm f/2.8, as in the pictures.
