Yashica-A shoots 6x6cm images on medium format film. The film is advanced manually and is uncoupled from the shutter mechanism. Also infinite exposures are possible on any individual frame, simply by cocking and firing the shutter without advancing the film. It also means that we must peer through a close-able, red framed counter window for advancing the film to the correct spot.
The very quiet, five-bladed leaf shutter is completely vibration free within the solid body of the camera. As the camera has no meter, only full-manual exposure is possible, with shutter speed and aperture controls arrayed around the taking-lens. The only shutter speeds offered are the non-standard 1/25, 1/50, 1/100 and 1/300 plus Bulb. There is no self-timer, and none of the exposure settings are viewable from the finder. Focusing is smooth and precise with the pop-up focus assist lens in the finder, and the focus knob conveniently has depth of field and distance indicators on it.
While earlier examples have the 80mm f/3.5 Yashimar lens, mine has a Yashikor of the same specifications and a similar triplet design. The Copal leaf shutter has five curved blades, and can flash sync at all speeds with the PC-sync port. The aperture is steplessly controlled via a lever that circles the side of the lens, with full-stop markings along its travel. A flash shoe on the side of the camera holds flashes, triggers or accessories.
