The standard viewfinder is the AE prism finder with center-weighted and spotmetering options. This theoretically increases focus accuracy and provides sharper pictures.Unfortunately the Vacuum Film Insert works only with 220 films due tointerference of the backing paper on 120 films. A mechanism createsa vacuum during the moment of exposure and keeps the film flat on the pressureplate. The Vacuum Film Insertis a Contax exclusive. The regular insert accommodates both120 and 220 film types by rotation of the pressure plate. There are three filmbacks currently available for the Contax: Standard,Polaroid, and Digital.įor Standard, two inserts are offered. Theshutter is electronically controlled and has a top speed of 1/4000s, which isanother first for medium format. The Contax utilizes the first medium format metallic-blade shutter. (All current Contax lenses are shutter-less and utilize thefocal plane shutter in the camera body.) One example is the possibility of leaf-shutterlenses in the future. Electronic linkages do away with mechanical wear and tear and providedesign and expansion flexibility. The use of Carl Zeiss T*lenses presents another appealing feature.Ĭommunication between the lens, body, filmback, and viewfinder is exclusivelyelectronic. It competes directly with the Pentax 645N and Mamiya 645 AF (to bereleased in October, 99) and is currently the only AF medium format SLR tofeature an interchangeable viewfinder and a filmback. The Contax 645 represents the second AF medium format SLR currently on themarket.
