Focusing Helical focusing system built in to each lens;
Focus ring rotations 90Â° on 45mm f/4 & 65mm f/4, 60Â° on 100mm f/4.5.
Shutter Bronica No. 00 type electronically controlled lens shutter in each lens, shutter speeds; B, 1 to 1/500 sec. (on manual without intermediate speeds), 8 to 1/500 sec. (on aperture-priority AE mode, 1/12-stop increment control) 8 to 1/750 sec. (on programmed AE mode,
1/12-stop increment control.) Electronically timed self-timer with 10 sec. delay time.
Aperture Electro-magnet driven aperture blades with f/4 to f/32 (45mm f/4 & 65mm f/4), f/4.5 to f/32 (100mm f/4.5.)
Film Advance By rapid winding lever placed on top of camera with either 186Â° single stroke or ratcheted strokes, with 12Â° stand by angle.
Coupled Rangefinder Dual-image superimposing real image optical system, with 53.5mm base line (effective base line: 33mm)
Viewfinder Inverse Galilean optical system with coupled rangefinder bright frames automatically switched between 65mm and 100mm lens and automatically corrects parallax, finder magnification, 0.6X, viewing field 81% at 3 m.
