manual focus 645 film camera that takes either 120 or 220 roll film
vertical (“portrait”) framing due to horizontal film movement
nice viewfinder with crisply defined edges to the rangefinder focusing patch but it is designed to be used with the right eye in a precise position to allow visibility of the viewfinder information at the left side
leaf shutter lenses with no mechanical cocking by the body (a motor built into the lens does this instead)
automatic cloth curtain unfolds as a “dark slide” when changing lenses (unike the Mamiyas which require manual management)
center weighted non-TTL average metering, adjusting to the focal length mounted on the body
requires 2x CR2 batteries to operate
parallax-compensated viewfinders with framing for 65mm and 100mm lenses (135mm on early bodies with serial numbers starting with a “0” but the 135mm lens was too difficult to focus and thus replaced by the 100mm lens)
when shooting at close focus, recommended aperture s f/11 given the narrow DOF and rangefinder focusing
there is an external finder option for framing when using the 45mm lens
self-timer
multi-exposure possible
standard cable-release socket on shutter release
half press shutter to confirm exposure
AE priority or Program exposure modes with +/- 2 EV exposure compensation and 25-1600 ISO settings
shutter speed Bulb plus 1sec to 1/500th sec (8 sec to 1/500th in AE mode and 8sec to 1/750th in Program mode)
hotshoe with dedicated protocol which sends aperture and ISO to the flash and thus requires Bronica Speedlight RF20 flash
flash sync socket under the lens
