The Bronica RF645 is a medium format rangefinder with interchangeable lenses made by the Japanese company Bronica. It captures 6×4.5 images onto 120 or 220 film. This camera has been introduced in 2000 and discontinued in 2005, with Tamron continuing support until 2012.

Camera design
The relatively classic design of a rangefinder camera has been enhanced with modern techniques and some very innovative choices. The body and lens communicate with each other through a mechanical rangefinder coupling and electronic contacts for lens identification, aperture setting and shutter release.
Most notable features include
- vertical ("portrait") framing due to horizontal film movement, much like some earlier folders
- leaf shutter lenses with no mechanical cocking by the body (a motor built into the lens does this instead)
- automatic dark slide when lens is removed : a cloth curtain unfolds to protect the film from exposure
- center weighted average metering (non TTL), adjusting to the focal length mounted on the body
- Program mode where the body sets the aperture in the lens electronically
The camera relies upon 2 CR2 batteries to operate, and will not work without them.
Viewfinder
The vertical viewfinder is a good design, offering clear vision, distinct patch and good resistance to flare. Frames for 65mm and 100mm lenses are available (and 135mm on early models), and are paralax-compensated. An additional external finder is provided for the 45mm lens.
Viewfinder displays selected shutter speed and aperture, as well as indicators for AE lock, exposure compensation, P or A mode, need to advance film, and low battery.
Lenses
At the time the camera was issued, three lenses were advertised : 45mm/4, 65mm/5 and 135mm/4.5. Shortly after that a 100mm/4.5 was announced to replace the 135mm which was too difficult to focus on some bodies. All lenses seem to have very good reputation in terms of sharpness and bokeh.
Controls
The Bronica RF645 offers the following controls :
- focus
- aperture
- shutter speed / exposure mode (Aperture priority or Program)
- AE lock
- exposure compensation
- film ISO setting
- self timer
- multiple exposure
- 120/220 film type selection
