Pentax 645
The Pentax 645 is a professional medium format SLR camera that produces 6×4.5cm images on 120/220 roll film. Introduced in 1984, this modular system features interchangeable viewfinders, focusing screens, and film backs, along with autofocus capability through compatible lenses. The camera offers both manual and aperture-priority exposure modes, with shutter speeds from 1/1000s to 4 minutes. Known for its ergonomic design that mimics 35mm camera handling, the 645 made medium format photography more accessible to professionals transitioning from smaller formats. Its extensive lens system and reliable build quality established it as a popular choice for portrait, wedding, and commercial photographers seeking the image quality benefits of medium format.
