The Topcon Unirex is a 1969-1973 SLR from Tokyo Kogaku offering TTL spot or averaging metering.
The Unirex is most unusual for a SLR in having a leaf shutter not within the lens (or between a permanently attached rear section of the lens and an exchangeable front section), but instead behind the lens, which is exchangeable in its entirety.
Specification
- Lens mount: UV Topcon bayonet mount. The mount included a locking facility when Topcor UV lenses are attached.
- Viewfinder: Fresnel screen with central mirco-prism focusing spot, and a fine focusing ring around this. Magnification x 0.75.
- Shutter: Seikosha SVL leaf shutter in camera body. Speeds 1 sec to 1/500th plus B and self-timer. 1/15th to 1/500th available for auto-exposure (in red: lower speeds in black). 10 sec self-timer (set MVX switch to V, and press shutter release).
- Meter: Open aperture needle based (f stop shown) TTL dual metering system. Two CdS cells are located either side of the viewfinder, and a third - used alone for spot metering - is located behind the mirror. Average brightness using all three CdS cells. Needle-pointer shows f-stop in viewfinder, including under and over exposure warning zones.
- Exposure: Automatic shutter speed priority, or fully manual. Lens aperture setting ring is part of the camera body, so maximum lens aperture has to be dialled-in using a separate control (the film speed is set by aligning with the maximum lens aperture.
- Film Speed: 25 to 1600 ASA (selector dial has a locking lever). There is also a DIN scale on the opposite side of the dial.
- Flash: Cold shoe and PC terminal. M and X sync (set to X for daylight photography). The X setting would have also been used for class F and S flash bulbs.
- Film Advance: Single long stroke lever (180° with 20° offset).
- Frame Counter: Automatic count-up and reset.
- Rewind: Via crank and bottom release button.
- Size: 141 x 93 x 59mm (W x H x D).
- Battery: 1 x 1.35v PX625 mercury battery (use the equivalent WeinCELL MRB625 zinc air cell).
The Unirex EE lacked the spot metering option. Both camera models were also available in black.
