Mamiya 7
The Mamiya 7 is a medium-format rangefinder system camera manufactured by Mamiya. It was introduced in 1995 and discontinued in 2014. Features
The Mamiya 7 has a coupled viewfinder window which displays frame lines appropriate to the lens mounted, but only for the 65 mm, 80 mm, and 150 mm lenses. The 43 mm, 50 mm, and 210 mm lenses require an external viewfinder to be inserted into the hot shoe for composition. The camera has a built-in dark slide that allows the manual-focusing electronic leaf shutter lenses to be changed with film in the camera. It can operate in auto exposure, auto exposure lock, and manual modes. It captures ten 6 cm × 7 cm images on 120 film rolls, and 20 on 220 film. The camera also features a self-timer, hot shoe, and flash synchronization terminal. An optional panoramic adapter allows 24×65 mm images to be captured on 35 mm film. The Mamiya 7II was introduced in 1999. It features an improved viewfinder and multi-exposure capability. Lenses
