Selectronic was a series of higher priced 35mm camera models sold by Agfa. The brand covered viewfinder and rangefinder cameras as well as SLR cameras under one name. The target market for these cameras were advanced amateurs.

Viewfinder

Selectronic Sensor was a viewfinder camera derived from the Optima Sensor 500, with a similar CdS cell for aperture priority metering, and a three element lens, but featured a new Paratronic electronic shutter.

Rangefinder

Selectronic S Sensor was a luxury rangefinder model with higher quality Tessar style lens and improved metering display.


Both Selectronic cameras, introduced in 1970, were made by Agfa in their Munich factory.


SLR models

Three Selectronic SLRs featuring the K mount were introduced in 1980. Agfa-branded lenses, as well es the cameras themselves, were in fact manufactured by Chinon. The only difference between these cameras and their Chinon originals were the Agfa-typical Sensor shutter release button and a more modern design.

Selectronic 1, the basic model, was based on the CM-4. It offered exposure metering but worked manually.

Selectronic 2 is an automatic (aperture priority) only camera like the CA-4.

Selectronic 3, the luxury model, was a CE-4 and could be switched between manual and automatic modes.


Selectronic 3 (SLR) Specifications


The specification of this camera is similar to, but not identical to its Chinon relative.

  • Lens mount: Pentax K bayonet.
  • Viewfinder: Pentaprism with central split image, microprism collar and ground glass. 16 LED's indicate shutter speeds and over/under exposure. Magnification: 0.87 x with 50mm lens set at infinity. Viewfinder coverage 92%. DOF by depressing depth of field lever.
  • Shutter: Seiko MFC electromagnetic metal blade focal plane shutter with vertical travel. Stepless speeds from 8 to 1/1000 sec. on automatic; 14 conventional speeds from 8 to 1/1000th, sec. on manual, + "B". Both automatic and manual speeds electronically controlled. Two stage electromagnetic shutter release (first activates the meter) with safety lock and separate provision for cable release. Electronically controlled self-timer at 5 or 10 seconds with front-of-camera flashing red LED indicator. Two seconds before exposure, flashing frequency of red LED increases. Self-timer can be cancelled even after system has been activated.
  • Meter: TTL, center-weighted averaging metering at full aperture using SPD (Silicon Photo Diode) cell. Half way depression of shutter release activates metering system.
  • Exposure: Auto aperture priority, or match-the-LED manual exposure (where the camera suggested speed LED is lit, and the user selected speed flashes).
  • Film Speed: 25 to 3200 ASA.
  • Flash: Standard X-synch hot shoe at 1/60th
  • Film Advance: Single stroke in an arc of 130° with 25° stand off. Coupling for motorized film advance with Chinon Power Winder. Multiple Exposure switch disengages film advance and frame counter.
  • Size: 135.5 X 85 X 50.5mm (W x H x D).
  • Weight: 485g.
  • Battery: Three 1.5V Alkaline batteries (LR44) or 1.5V silver oxide batteries (SR44). Battery test with LED indicator.
