YASHICA D AND 635
The Yashica D and 635 are equipped with f 3.5 Yashikor, a three-element triplet of 80 mm. focal length for both taking
and viewing lens. The shutter is the Copal MXV, giving speeds 1,½,¼, 1/8, 1/15, 1/30, 1/60, 1/125,1/250 and 1/500 sec.
and B for time exposures, with XM flash synchronization and built-in delayed-action release. The shutter speed and the
aperture are actuated by thumb wheels on either side of the shutter and are read off in a cut-out window above the finder
lens.
Focusing is by wheel on the side of the camera with distances engraved in feet and metres. A depth of field indicator is
engraved on the camera body above the focusing wheel.
The film transport is semi-automatic by transport wheel which locks when the next frame is in position. An automatic
exposure counter in the side wall of the camera shows the number of frames transported. A reminder disc showing the
speed of the film loaded into the camera is built into the film transport knob. An accessory shoe is fitted to the left-hand
side of the body, primarily intended to accept a flash gun.
The folding reflex finder hood, opened and closed by one hand operation, incorporates frame finder and focusing
magnifier. The focusing screen incorporates a fresnel screen giving enhanced brightness and even illumination.
The camera back is hinged on and incorporates a film pressure plate.
THE MODEL 635 has an additional transport knob, film counter and rewind control for using 35 mm. films in
conjunction with a 35 mm. kit supplied with the camera. This kit consists of 35 mm. auxiliary spool assembly, convertor
mask unit, film pressure plate, supporter shaft, adapter ring and frame finder mask, all contained in a small leather case.
The ground glass screen has red lines engraved on it showing the field of the 35 mm. size.
BOTH MODELS have a bayonet mount around viewing and taking lenses to accept bayonet-mounted filters, close-up
lenses and lens hood.
ACCESSORIES for Yashica D and 635 include filters for colour and black-and-white photography, close-up lens sets
with built-in wedge for parallax compensation, lens hood and hand grips.
Loading
1. Open camera back.
2. Insert the film and turn film transport knob until lateral double arrow or bar printed on the backing paper points to
the red markers on either side of the film aperture of the camera body.
3. Close camera back, the letter s (= start) will automatically appear in the film counter window.
4. Get film ready for first exposure by turning film transport knob until the number 1 appears in the film counter
window. The transport then becomes locked in this position.
5. Set film speed on the reminder disc by turning the ASA or DIN speed of the film used opposite the indicator dot
on the rim. This has no function as far as working the camera is concerned. It is simply a reminder.
Unloading
1. Wind off film, after all 12 exposures have been taken, by turning the film transport knob another 6 turns to wind
off the remainder of film and backing paper.
2. Open camera back.
3. Remove the exposed film, close back or reload with new film.
