Ricoh Auto 66 TLR

Semi-automatic 6x6 format camera with selenium light meter. Uses knob film advance with automatic stop at next frame. This model was sold from 1960-1964. In 1963 the list price was $79.95. Optional case was $10.95.

  • Taking lens: Riken Ricoh 8cm f3.5. This is a 3 element lens AFAIK. Accepts Bay 1 accessories.

  • Shutter: Seikosha-L shutter with speeds from 1/25 to 1/250 plus B and a flash setting. Shutter speeds are selected with the LVS dial (read from meter) so the actual shutter speed isn't known. LVS range from 8.6 to 16. Film speeds from 10 to 400 can be selected. Shutter has five blades. Self timer is provided.

  • Aperture: manually set from f3.5 to f22. Has 5 aperture blades. Aperture click stops: no info.

  • DOF scale: no info.

  • Viewing lens: Riken Ricoh 8cm f3.5.

  • Finder: Fresnel screen with clear center spot. No lines on screen. Sport finder and magnifier is provided.

  • Meter: Selenium (no batteries required) uncoupled "Light Value" meter.

  • Focusing: the taking and viewing lenses move in and out together during focusing. Unlike the Diacords the front panel does not move in and out. Focus levers protrude from the left and right sides of the front panel and are connected to the focus helical. As you focus in and out one lever moves up while the other moves down. Thus you can focus with either hand. Focus distance is indicated in feet and metres below the taking lens.

  • Film advance is done with a knob. Film advance is automatically unlocked after a photo is taken. Since the shutter is cocked manually, double exposures (intentional or not) are possible.

  • Film changing: Same as Diacords AFAIK.

  • Flash: X-sync only. Flash connection is done though a PC connector or the hot shoe.
