Mamiya's lighter interchangeable-lens 6x6 TLR — C220f, paired leaf-shutter lenses, bellows focus, 1982.
The Mamiya C220f is a medium-format twin-lens reflex from Mamiya, an early-1980s development of the lighter C220 branch of the interchangeable-lens C-series. It served as the more compact companion to the C330 bodies, keeping the C-series interchangeable paired-lens system in a simpler, lighter form.
It is a twin-lens reflex shooting 6x6cm square frames on 120 roll film, twelve per roll, and can also take 220 film. It takes interchangeable paired lenses on the Mamiya C bayonet, with taking and viewing lenses changed together and each lens carrying its own leaf shutter. Focusing is by a bellows moving the lens board for close focusing, and composition is through a waist-level finder on the ground-glass screen.
The C-series is the interchangeable-lens professional TLR, and the C220f suits portrait, landscape, studio and general medium-format work for photographers wanting the system's lens choice in a lighter body than the C330. It lacks some of the C330's automation but is simpler and less heavy. It is still larger than a fixed-lens TLR, with each paired-lens unit adding bulk.
When buying a used C220f, check the taking and viewing lenses separately for haze, fungus and separation, and confirm the lens-lock and mount seat the paired lens securely. Fully extend the bellows and inspect for pinholes and light leaks. Test each lens's leaf shutter and aperture, verify the film-wind and counter, and inspect the ground glass for brightness and the focus mechanism for smooth travel.
