Ricoh Diacord L Unbox – Collector’s Condition

Ricoh Diacord L Unbox – Collector’s Condition – YouTube.



The Ricohflex was a series of 6×6 TLR made by Riken Optical Industries (Ricoh) in the 1950s. The focusing rings around the taking and viewing lens are geared up for synchronous focusing, just as previous Kodak Reflex I/II. Its coated Anastigmat triplet lens provides great result in its class. The Ricohflex has a simple, modular-designed and low-cost box structure.

List of models:

  • Ricohflex III (1950 September)

The Ricohflex III of 1950 had a pair of similar Ricoh Anastigmat 1:3.5 f=80mm lenses with AR coated. It was the world’s first mass-produced twin-lens reflex camera. {C}

  • Ricohflex VII (1954 February) [with Riken or Seikosha Rapid shutter]

The model VII was released to the market on February, 1954. It had a Ricoh Anastigmat 1:3.5/8cm front-element focusing lens geared to the Ricoh Viewer 1:3,5/8cm lens for viewfinder focusing. Most of it had a Riken shutter with B mode and speeds from 1/25-1/100 sec. The shutter used the same lever to cock the shutter (pull up) and fire the shutter (push down). The Seikosha Rapid version comes with B mode and speeds from 1-1/500 sec .The camera has the capability of using 120 film or 135 film with the optional COLOR BACK insert. {C}

  • Ricohflex Model T (Made in Taiwan version)

Rocoh Rocohflex TLR

A list of TLR models produced by Ricoh.

Ricohflex Model I, II and V: These model numbers were never used.

Ricohflex Model III: was introduced in 1950. It has the same f3.5 Anastigmat lens as later models but apertures are marked to f22 (instead of f16). Has the Riken shutter with B, 1/25, 1/50 and 1/100 speeds. Compared to the Model VII it has a smaller viewfinder magnifier and a back locking mechanism that isn’t as good. It has a folding viewfinder shade which was changed to the pop-up type in the Model IIIb (photo) which also has the later style larger viewfinder magnifier.

Ricohflex Model IV: Introduced in 1952. Earlier ones are labelled IIII which was later changed to the more correct Roman Numeral IV. Shutter speeds of B and 1/25 to 1/100 are supported. I don’t (yet) know what the differences are from the III and IIIB models.

Ricohflex Model VI: Introduced in 1953, is a manual 6×6 format camera without light meter, using knob film advance with “red window”.

Ricohflex Model VII and VIIs: Introduced in 1954 and 1955, are manual 6×6 format cameras without light meter, using knob film advance with “red window”. Some have the Auto-Stop feature.

Ricohflex Model VII (Seikosha shutter): Introduced in 1954. Has Seikosha shutter with speeds of 1 sec to 1/500 plus B.

Ricohflex Model VIIM: Introduced in 1956. Has shutter with speeds of 1/10 to 1/300 plus B.

Super Ricohflex: Introduced in 1956, is a manual 6×6 format camera without light meter, using knob film advance with “red window(s)”. Some models came from the factory with the Auto-Stop feature (though red window was still present). It was also available as a user-installed option (photo). There were four versions of the Super Ricohflex with three of them having 1/10 to 1/200 shutter speeds but one have 1 sec to 1/500 speeds.

Link to the Super Ricohflex user’s manual.

Ricohflex Holiday: Similar to the Model VII, it has the Riken shutter with limited shutter speeds (B, 1/25, 1/50 and 1/100) but has a flash shoe and film reminder on the wind knob like the Super Ricohflex.

Ricohflex Million: Similar to the Model VII, but has a Riken shutter with speeds from 1s to 1/300. And hot shoe on side as well as PC connector on front panel. Photo coming soon.

Ricohflex Dia: The original Diacord. The name plate says Ricohflex so it is sometimes confused with the geared focusing Ricohflexes. Some Diacord G’s appear to have been nameplated Ricohflex which adds to the confusion. The Diacord L manual shows the camera with a Ricohflex nameplate. So L’s may also have been produced with the Ricohflex nameplate.

Ricohflex Dia M: A cheaper version of the with speeds from 1/10 to 1/300. Photo coming soon.

Ricohflex: The next version of the Dia. Has bayonet 1 fittings on taking and viewing lenses. Has Riconar 3 element taking lens. Photo coming soon.
