1. Numerous changes to the Accessories page. In addition to more information generally and revision of the layout, there is an example of a Minicam Synchron Junior flashgun and pages from catalogues including a downloadable PDF brochure featuring the Yashica Mat-124, Yashica-Mat, Yashica 635, Yashica D and accessories.
  2. Additional examples of Yashicaflex A-I and A-II models with Y.S.K. shutters (affects 66 Models and Yashicaflex A series pages).
  3. Whilst previously being non-committal, I have decided to refer to commonly called Yashicaflex A and AS models as models A-I and AS-II to reflect Yashima practice in user manuals whilst reserving Yashicaflex A and AS to generically mean grouping of A-I and A-II and AS-I and AS-II models. Confused? You can thank Yashima for that (affects Model Names, Yashicaflex A Series and 66 Models pages).
  4. Late model Yashicaflex AS-II found with 10 flag DIN film reminder on film winding knob and no film counter reset button. Puts it well into Yashica C and LM production, probably 1957 (affects 66 Models page).
  5. The first three Yashica Flex S examples in my database have Tri-Lausar lens sets confirming this as the release specification (affects 66 Models page).
  6. Additional MolfoReflex information added including example and original ad.
  7. Recognition of a Yashica A sub-series, possibly Sugiyama's Yashica A-III and most likely a Japanese domestic market variant. All have grey leatherette, no hood logo and metre focusing scales (affects 66 Models).
  8. Decided that there was no purpose for the “B” in Yashica Flex B and that it must be collector invention. Then changed everything back when a 1955 Swedish ad included the “Yashicaflex B” (late example, after release of the Yashicaflex A, affects Model Names and 66 Models pages). Note, may still have been released as simply “Yashica Flex”.
  9. Although the evidence is that they were released as the “Yashica Flex” or “Yashica Flex B” and “Yashica Flex S”, as a consequence of the release of the Yashicaflex A series, they also changed their names to the single word form (see 8 above). I have decided to continue with the two word form for the Yashica Flex B because the change occurred very late in its model run but the change for the Yashicaflex S probably occurred only a few months after its release (when the Yashicaflex A series was released) and I have now decided to generally refer to it with the single word form “Yashicaflex S”. When talking about its release or specifically the versions with NKS shutters, I may still use the two word form. THIS REPRESENTS A MAJOR U-TURN ON WHAT I HAVE BEEN PREACHING! This affects lots of things but particularly Model Names and 66 Models.
  10. 29 January 2012: Introduction of “Updates Log”.
  11. 1 February 2012: Revised Yashicaflex names and 44 series dates in “Yashica TLR Models & Specifications Table” (affects Models & Specs page).
