Buying guide

The RF645 (2000-2005) was a medium format rangefinder with three interchangeable lenses in its final form (45mm f/4, 65mm f/4, 100mm f/4.5). Early bodies were made for a 135mm lens, which was replaced by the 100mm because it was too hard to focus with the short rangefinder base. Rarer than the Mamiya 7. Test all electronics thoroughly; Tamron supported the camera until 2012, so parts are now very hard to find.
