The first camera made by the fledgling camera maker, Yashima, later to adopt the name of its Yashica cameras, was a twin lens reflex (TLR) taking twelve 6 cm x 6 cm negatives on 120 format film. Like many other TLRs, it was patterned on the Rolleicord and used a separate viewing lens matched to the taking lens below it, the camera front panel moving in and out to achieve correct focus. The view through the waste level finder is very similar to what the taking lens is seeing except that the view is correct side up but reversed left to right, courtesy of the 45 degree mirror (hence “reflex”). Yashica went on to make movie cameras, sub-miniature cameras and various categories of 35 mm cameras but the offspring of the first model would continue in production for the next 33 years.
This site is dedicated to understanding and preserving the details and development history of the company's TLR cameras from the first model Pigeonflex through to the Yashica Mat-124G. Whilst the content is possibly of greatest interest to collectors, my original intent was to help anyone that wanted to identify a Yashica TLR model or find out more about the camera that they had acquired. I hope that I have also added enough information for users, meaning actual photographers, to find the site interesting. The story of Yashica is a story of post-War Japan and development of the Japanese photographic industry - I'm not pretending that I am contributing to that understanding but keep the context in mind when thinking about Yashica history.
Both 6x6 120 film and 4x4 127 film format cameras are included. As a group, the 4x4s were commonly referred to as “44” and with later user manuals and boxes for the 6x6s, Yashica started adding “66” to the names. These are the terms I will use to distinguish between the two format groups.
To clarify my reasons for developing this site and justify why my take on early Yashica model history is sometimes at odds with other sources, I need to explain what I believe are some of the key issues in regard to the history of Yashica TLR models.
If you are not interested in all the historical detail and controversy and just want to look up a particular model, go to “66 Models” or “44 Models”, as appropriate or the table “Yashica TLR Models & Specifications Table”. The sidebar links to the pages of the site, think of them as chapters.
The information on this site developed out of frustration at the lack of accurate model detail available on the Yashica TLRs, particularly the Yashicaflex series and the first of the Yashicas. Some prominent sites have obviously incorrect information, eBay sellers often use these sites for quick identification and you can see how wrong thinking has grown.
In the beginning, Yashima was just another insignificant company trying to get a toehold in the photographic industry. There would not have been too many, if any, magazine articles or other commentary about the early company or its products, at least until the Yashica Flex model S arrived on the scene. Unfortunately, Yashica seems to have done little to formally document its own history and what there was, seems to have been lost with the Kyocera takeover.
The various “-pedia” sites, previously somewhat lacking in model detail but otherwise able to provide references for some of the company's milestones, are not immune from ill-informed comment creep by otherwise well intentioned and enthusiastic Yashica owners. Some of the sites' early 1950s model commentary seems to rely on period Japanese advertisements, many from Asahi Camera magazine. These are an excellent and original resource but still require researchers years later to interpret momentary snapshots in time. For example, the Yashica model list of Japanese Wikipedia claims that the shutter on the original Yashica Flex B was changed to a Copal with 1/10 to 1/200 speeds (presumably, from an NKS-FB with a full range of speeds to 1/300). That is repeated on several Japanese sites but is most likely to have been a mis-identification of a model A-I example which is quite rare in Japan.
Also, it's only natural that websites and commentators outside of Japan have concentrated on models that were either commonly bought back by Service personnel in the early to mid-1950's, or were export models. On the other hand, there is little if any information on Japanese sites about models that were export only and that includes the Yashica C, Yashica LM and possibly the earlier Yashicaflex A-I and AS-II and I suspect some of the crank wind models. The Yashica 44A may have been available in Japan but only after a delayed release. Also, the early export Yashica A was nowhere to be found; the Japanese market name “Yashica A” seen in advertising material had Yashicaflex on the nameplate and was sold in export markets as the Yashica B and when the export Yashica A was finally released in Japan, it was without the hood logo and called a Yashica AIII (but not on the nameplate). There was also the earlier cousin, the Rookie. If you read on, it may become clearer....
In quite a few respects, not only my research and conclusions but the visual evidence itself, contradicts the doyens of the collecting world, McKeown internationally and Sugiyama in respect to Japanese cameras and on whom, some say, McKeown may have relied on (I will specifically address Sugiyama in another section). Well, maybe not Sugiyama so much, it's what he has left out and how he has been interpreted by others. However, they are cataloguers and generalists focused on the collector’s market rather than the intricacies of individual maker history and models.
Two related mistakes often made are assuming budget models are older than more sophisticated models and this comes from thinking that models were released in a linear fashion, i.e. one after the other, when even at the end of 1954, there were already a number of Yashicaflex models in production simultaneously. The Yashica A, B, C and D are not developments of each and were not released in that order. The A and C came first in 1956 and the B and D came some 2 years later. Yashima/Yashica initially used the letters “A”, “B” and “C” for Yashicaflex models to denote where the camera sat in the model range based on feature set, the A series being the most basic and released after the first B model. The letters “A” and “B” were also reused for unrelated later model Yashicaflexes. The Yashica D was probably the only true “alphabet” release as the next available letter (the subsequent “E” may also have been but Yashica also used the term “electronic eye” to describe the selenium cell based automation and there was a similar 35 mm “EE” model, either way, it could simply have been a convenient coincidence).
The first 1964 edition of the popular Focal Press Yashica Twin Lens Reflex Guide by W.D. Emanuel helped to set the incorrect thinking in stone by claiming that the Yashica D developed from the A and included a flow chart demonstrating this and that has appeared in many other places. The impact of the Yashicaflex models was completely ignored (the Yashica D was in fact a rebadged, Japanese market, late model Yashicaflex B). He may not even have been aware of them but in any case, his user guide was for then current models, not a history book.
A third mistake may be related to Yashica/Kyocera itself, or at least that is where the credit/blame appears to belong. Often, precise introduction and discontinued dates are quoted to the month which gives an impressive air of authority. The introduction dates particularly are widespread throughout the net. One source is the useful book, “Collector's Pictoral Encyclopaedia & Value Guide to 6x6 TLR Cameras” by Karl F. Kahlau which lists model release and end dates and production numbers “partly supplied by Yashica/Kyocera”. Another is an archived page, “A Partial History of Yashica TLRs” , from a defunct Yashica site authored by Alan R. Corey, listing similar release and discontinued dates “from a table supplied by Yashica/Kyocera”.
Both the book and the site, A Partial History of Yashica TLRs, agree on many of the dates but others are exactly 12 months out with each other even though both claim to be relying on similar sourced information. And there are other differences too. That is problem number one. The production numbers in the book may all be absolutely spot on (it's not possible to verify one way or the other) and so may be many of the dates in both documents but problem number two is that it is very easy to prove using actual Yashima/Yashica documentation from the period that there are some gross errors of fact in what is claimed to be the original Yashica/Kyocera supplied dates. (The problems are not limited to the following examples, other discrepancies are dealt with as they occur.)
Yashica A, C & LM
There is nothing obviously special about the Yashica A, C & LM models, they are relatively minor upgrades of existing Yashicaflex models (Yashicaflex A-I plus speed increased from 1/10-1/200 to 1/25-1/300 speed, Yashicaflex C plus MX shutter and Yashikor viewing lens, Yashicaflex S plus MX shutter, updated lenses and exposure meter changes or, as Yashima describes it, Yashica C with meter). However, they are fundamental to understanding Yashica history and the changeover from the Yashicaflex to Yashica name. Although there is evidence of earlier exports, these three models spearheaded Yashima's all out export drive into the US and other markets whilst Yashicaflex models continued in Japan:

Of the examples shown, Yashica A is from 1957 to 1958 (later focusing hood logo and trim), the other two are from 1956 to early 1957. A 1956 to early 1957 Yashica A focusing hood is below (there are 18 similar in my database). No 1958 Yashica cameras had the all black logo or outside silver square, in fact neither the Yashica-Mat nor any model released after April 1957 had that trim:
(Detail from larger web image)
A Partial History of Yashica TLRs quotes release dates of October 1956 and March 1957 for the Yashica LM and C respectively and April 1958 for the Yashica A (1958 is quoted almost everywhere, my edition of McKeown's has 1959, presumably based on Sugiyama's Japan only AIII variant) whilst the book uses dates of October 1957 and March 1958 for the Yashica LM and C (exactly 12 months difference - unconnected coincidence?) and no date for the Yashica A. However, here is a December 1956 (see bottom left corner) US ad featuring all three cameras together (the same ad appears on page 47 of the January edition of U.S. Camera):
(Detail from web image)
(Click on ad for larger image)
And, there is a Japanese brochure published on 15 December 1956 referring to a December US review of the Yashica C and LM (the focus in the brochure is on the Yashica C - the Yashicaflex C ancestor was still being sold in Japan). There is also an April 1957 Swedish ad and three US ads from 1957 featuring the three cameras together with the “new” Yashica-Mat (released in April 1957). This is one of them:
I'm not sure of the edition of this Modern Photography magazine but the same ad appears on page 14 of the May 1957 edition and a similar but double page spread appears on pages 172 and 173 of the April 1957 edition of Popular Photography presenting the “new” Yashica-Mat whilst implying that the other three arrived “first”. There is also an early US brochure featuring the three “new” cameras together without the Yashica-Mat. To me, it is absolutely clear cut that the Yashica A, C and LM were all released simultaneously in 1956 and that they all appeared in numerous ads together in early 1957. Although December 1956 is already confirmed in both the US and Japan, I think that the October 1956 date claimed in Alan R. Corey's “A Partial History of Yashica TLRs” is very likely to be correct for the Yashica LM and therefore, for the other two cameras as well (his 1957 for the Yashica C and 1958 for the Yashica A are clearly erroneous). I say that because there is an ad featuring the three models in U.S. Camera that is claimed to be from the November 1956 edition and it starts with:
“YASHICA is here!
Three months ago, many camera store owners had a preview of the Yashica cameras.”
Given magazine lead times etc, an October release is very plausible. Pre-production models must have been floating around since the middle of the year. Clearly, Yashima was making a concerted effort and with models ready, I can't imagine a release too close to Christmas.
However, if the marketing material is not enough proof, then there is the forensic evidence. The focusing hood (as noted above), spool knob and locking lever trim details on the earliest examples of the three cameras are consistent with the 1956 period and match the Yashica Rookie released earlier in 1956. The Yashica LM and C were released with film counter reset buttons (which they lost well into their production runs). Cameras accepted as released in 1957, the Yashica-Mat, Yashicaflex AS (new model) and Yashicaflex B (new model), had newer trim styles already and were also fitted with fully automatic film counter reset from the outset. Except for colour, all three cameras have identical user manual covers for their first two editions, also unusual for the 1950s period.
It may be be a matter of interpretation or translation but I suspect that the data attributed to Yashica/Kyocera has been assembled many years after production of the respective models and with what purpose, source records or due diligence, we don't know. Elsewhere on this site, you will find that there were Japanese market cameras with “Yashicaflex” on the nameplate but which were marketed as “Yashica” models and which borrowed names from quite different export models - this may be a factor too. Whatever the reason, please take any such apparently authoritative information with a grain of salt and keep an open mind and weigh up the evidence when presented with conflicting information from this site. You will note that with the author's kind permission, I do reproduce much of the Yashica/Kyocera sourced information from Karl Kahlau's book later on.
The Early Models
Here I am simply floating the contradictions between observation and often quoted dates which can probably be traced back to a single source. The Pigeonflex is claimed to be released in March 1953 and the mildly revised Yashima Flex in October 1953. I have seen no evidence which would question (or confirm) those dates. With a new nameplate, the almost identical Yashica Flex B (old model) is claimed to be released in December 1953 and the iconic Yashica Flex S with exposure meter is claimed to be released 10 months later in October 1954. The Yashima Flex was certainly in production longer than a few months - it progressed through three versions of the NKS shutter, two distinct nameplate styles and several iterations of focusing hood as well as being advertised in a Japanese magazine in February 1954.
In the same context, there is mounting evidence, albeit circumstantial, that the Yashica Flex B and more advanced Yashica Flex S were released near simultaneously with different specs aimed at different price points and that the release date was earlier than October 1954 but significantly later than December 1953. The issues are dealt with under the individual model entries in 66 Models but the main indicators are shared bodies between the Models B and S with film start marks (of no use in the Yashica Flex B), shared shutter initially (NKS-FB), same lens name on early examples of both (“Tomioka Tri-Lausar” whereas late example of the Yashica Flex B changed to simply “Tri-Lausar”, perhaps when the Model S changed to “Heliotar” lenses), early examples of both had the same pattern of first four ring locking knobs on the base and then three ring and the flash sync changed from the ASA type to PC type at a similar time in production. Both shared almost identical boxes except for “Model S” on one. Both the Yashicaflex Model B and S were still being advertised together in Sweden in March 1955 and also in what appears to be quite an early Japanese flyer below. Also, if the Yashica Flex B was the first and only model Yashica Flex when it was released, why did it need to be called “B”?
The first of the Yashicaflex A series models was probably launched in October 1954, as claimed. These were a new, separate budget line sold alongside the Yashica Flex model S and later, Yashicaflex model C, with a more basic shutter than their predecessors and with new budget lenses, Yashimars, only found on A series cameras including the early Yashica A and its near twin, the Yashica Rookie. The trim features clearly date the Yashicaflex A series as a later release than the Yashica Flex B and later than the first of the Yashica Flex S variations. Most reputable sources are in agreement, yet some of the same sources claim that the re-badged Swedish market MolfoReflex was released in 1953, not realising that behind the nameplate it is simply a Yashicaflex A-I and by its slightly later trim, probably from early 1955.
The biggest and most common confusion is regarding the names of these models:
(Images courtesy of Tom Heckhaus)
1954 Yashicaflex AS-II, 1957 Yashicaflex AS-II and 1957 Yashicaflex AS.
The two cameras on the left and in the centre are absolutely, definitely, NOT early forms of the Yashicaflex S, the first Japanese camera with built-in exposure meter, as claimed on so many sites and blogs (the examples a little further below are). They are slightly later Yashicaflex AS-II examples based on the budget A series feature set (there is a similar model with red window instead of film counter, the Yashicaflex AS-I, mentioned in literature but not yet found). This is 100% provable from original Yashica documentation including user manuals with photos, ads and brochures, some of which appear elsewhere on this site. Here is one:
(Brochure courtesy of Tom Heckhaus)
The AS-II shares the basic body and Sekonic CB-1 exposure meter of the Yashicaflex S but not the lenses or shutter. In “Yashicaflex A Series”, it can be seen how the model designation makes logical sense; “A” for A series, “S” for Sekonic meter and “II” for film counter with auto-stop winding.
(Images courtesy of Tom Heckhaus)
1954 Yashicaflex S and 1956 Yashicaflex S for comparison. Note the Bay 1 filter mounts and different nameplate script in the style of the earlier Yashima Flex and Yashica Flex B (old model). Note also that both the Yashicaflex S and AS-II have the same early and late body types and trim proving conclusively that they are largely concurrent models.
Although the camera on the top right is called a Yashicaflex AS by Sugiyama and on a number of sites, I previously found it hard to accept that it could have the same name (the AS-I and AS-II do have the extra “I” and “II” suffix but Yashima often referred to them collectively as “Yashicaflex AS”, including in the instruction manual and sometimes also forgot about the “I” in AS-I). A camera has now turned up with its original box and user manual. What could the “AS” possibly signify for this camera? An example of early “retro”? Possibly, this is one of three Japanese market Yashicaflex models with recycled model names released within a few months of each other.
The operation of the Yashicaflex model AS-I (also called “model-AS” and “model AS”) is mentioned in two user manuals, one to two years apart, and it is listed as a model in a third manual. In each case, reference is also made to its close cousin the Yashicaflex AS-II (confusingly, sometimes this also is referred to as the “model AS” but clearly different to the AS-I) of which there are plentiful examples, yet there have been no confirmed sightings of the AS-I. The Yashicaflex model A-III with 1/500 Seikosha Rapid shutter is referred to in one user manual and similarly, has never been sighted, although five examples of what might be later versions with Copal MXV shutters are in my database and photos of two are on this site. If they are not Yashicaflex A-III examples, they themselves are a mystery model. The Yashica Hi-Mec is not mentioned anywhere but there are two examples in my database. There is a photograph of a Yashica Auto 44 in Sugiyama's book and Collectiblend records a single sale in 2003 but there are no other confirmed sightings.
My own thoughts are that the Hi-Mec and Auto 44 may have belonged to limited pre-production runs of what turned into the Yashica LM and Yashica 44LM respectively. These are the only two of all the models identified on this site without any mention in ads, brochures or user manuals.
If anyone has photos or information which will cast some light on these cameras, please contact me (see contact details below).
Except for non-controversial dates, background information about the Company and general matters, I have tried not to rely on third party sources or existing narrative on websites, at least without testing it in some way. My main sources for details about cameras have been user manuals, ads, brochures, catalogues and observing cameras displayed on the internet and offered at on-line auctions (currently, there are over 3,200 cameras in my database with serial numbers and trim details listed and with photos of many more examples). For the Yashicaflexes and earlier models, I have come to rely heavily on Japanese brochures and sites. Plus I have a few representative examples starting with a Pigeonflex and other early models.
This is a team effort and along with a group of long-term collaborators, there is a steady stream of correspondents with interesting examples of cameras, stories etc.
Throughout the site, I have tried to present evidence and explain my reasoning but inevitably, with a site like this, there will be some guesswork. I hope that I have made it clear when that occurs. When conflicting information turns up, I try not to assume that one view or the other is wrong. More often than not, the problem is about interpretation and the question becomes “why?” I have found that whenever I have made assumptions based on “logic”, I have inevitably been proven wrong by real events when they have become clearer. Nevertheless, I have made one such massive leap of logic on the Pigeon Loft page. That doesn't affect Yashima history or models but I do apologise in advance to those interested in the later Pigeonflex models - be prepared for my theory to be proved totally wrong in the future!
I have focused on camera models and development history rather than corporate history which I can't really add to, or camera operation which is all basically similar and is well documented in user manuals. PDFs of manuals for many models are available for download with donation from OrphanCameras.com, and I can be contacted by email for the missing Yashica LM with reset button and Yashica Mat-LM manuals. On the 66 Models and Ownership pages are links to PDFs of the historically interesting early Yashicaflex A, Yashicaflex AS, Yashicaflex S and combined Yashicaflex A & C and Yashica Auto user manuals. A general resource, the first edition of the Focal Press Yashica Twin Lens Reflex Guide by W.D. Emanuel is available for viewing or download from 3106.photography but ignore the model development history.
My name is Paul Sokk. I am an Australian of Estonian descent. Since 2003, my photography, mainly amateur, has been pretty much digital. Before then, my format of choice was 35 mm but in the early 1970s, as well as weekend wedding work, I did undertake two years of commercial photography training based around the 4"x5" view camera before deciding not to give up my day job. Now I miss the look and feel of metal, fully mechanical cameras. In addition to the odd example of an obligatory folder and Japanese rangefinder, I have a few early Pentaxes (I remember admiring my first one as a young lad and a Pentax was also my last serious 35 mm film camera), a few early FED & Zorki Leica copies (cheaper than the real thing and of interest in connection with my Estonian heritage, not to mention that for a brief period of post SLR adventurism in the 1970s, I shot a Zorki 4K) and some Yashica TLRs (the first affordable TLR that came up on eBay and now some more have joined it, “for research”, you understand). I have come to admire the Yashica TLR as an effective photographic tool available to almost anyone, both then and now, not to just those with deep pockets. I don’t consider myself to be a real collector but I do take documenting Yashica TLR history rather seriously, otherwise it wouldn’t be worth telling. And there is quite a lot to tell.
As it is an Australian site, I try to conform to standard Australian (i.e. largely British) spelling e.g. metre, grey, colour and amateur, unless something is specific to the US market. Note however, when I refer to focusing scales, I use the words “metre” and “feet” which appear on the focusing knobs rather than e.g., “metric” and “imperial” scales. “Imperial” is probably confusing for some cultures including Australians born after 1970 and Americans who apply their own terminology to it.
I can be contacted by email at firstname.lastname@example.org and am happy to discuss things Yashica or debate any of my conclusions - if there is better information, I will readily accede. Any contributions used, e.g. ideas, words or images, will be acknowledged. I am also on the lookout for manuals, brochures, ads, books etc that refer to the Pigeonflex to Yashicaflex period or accessories generally and also to The Mystery Models noted above. These could be either original, paper copies or electronic copies.
Some correspondents have asked me “how much is my camera worth?” This is one area where I have very little expertise. I am not a collector as such and am not familiar with sales on specialised auction sites nor do I subscribe to auction result bulletins or other market intelligence reports. Most of my research is web based and any views I have about value, and please note that most of the time I am not thinking about value unless buying something for myself, are derived from on-line auctions. My principal response is to refer correspondents to the completed listings history of such auction sites. And remember, a camera, or any item, is only worth what someone will pay for it at the time that it is offered for sale. McKeown says something similar but with a bit more authority. If you have an interesting camera and are happy to share serial numbers and perhaps a photo, I will be pleased to try to help but I can tell you now that there will be no magic number at the end. Also, before you contact me, please read the guide that I have prepared, “Valuation & Selling”, on the Ownership page.
The first iteration of this website was as a page accessed from Barry Toogood’s Yashica page of his excellent WWW.TLR-CAMERAS.COM. Barry and I did not, and it seems still do not, agree on a number of historical aspects but nevertheless, he very generously encouraged me to develop my ideas and then hosted the result. I am indebted to him for both the idea that has become Yashica TLR and the work he put into dealing with my dozen or so revisions which ended up as, I think, three distinct iterations of that original page. I also thank him for putting me onto my Pigeonflex.
My decision to turn my page into a site evolved from becoming involved with two amazing Yashica TLR collectors; Tom Heckhaus from the US and Leigh Harris from Australia. These guys are serious collectors with many years experience with Yashica TLRs and other collections. All three of us have come to share a similar view of Yashica TLR history and I know that Leigh and I have both gone down similar blind alleys in our respective pasts. Some of Tom’s information, including photos, had already appeared on my page courtesy of Barry. Some of the information concerned Yashicaflex history and I used a poor quality photo of a user manual from a well known auction site to illustrate the point. At that stage, none of us had contacted each other. Later I found out that Leigh had bought the user manual (and camera that it came with) - serendipity.
Most of the photographs on this site are courtesy of Tom Heckhaus – in fact I have used Tom’s photos to maintain some consistency in look. Some of the photographs are courtesy of Leigh – he has some unique examples. Correspondent and exposure meter aficionado Simon A. Spaans provided details and photographs of the differing exposure meter arrangements on the Yashicaflex S and Yashicaflex AS plus I have used some of his information in clearing up the origin of Yashica branded accessory meters.
A more recent recruit to the band of contributors is Göran Årelind from Sweden. Göran is a dedicated user of film cameras but in the process, has collected more Yashica TLRs than he cares to admit to, including a trio of MolfoReflexes, and has become quite skilled in repairs and restoration. Many of the photographs of accessories, as well as a number of cameras, are his and he has also provided me with brochures and ads. He has been investigating MolfoReflex history which has led him to a wider review of Yashica marketing and the rise and fall of TLR cameras in Sweden. More recently, he has added an article on Shutter Speed Testing.
Another new contributor is Sandu Baciu from Canada. He and his wife Alina have an extensive collection of Yashica TLRs including early models. In a very short time, quite a number of his photos have appeared all over the site and he was the inspiration for the “The Pigeon Loft” page with both his Yashima and Shinano Pigeonflex models and the “Prototypes & Specials” page with his Yashica Mat-124G based stereo camera. Sandu has managed to identify a number of unusual features and variations and has provided photos of previously unobtainable items like Pigeonflex, Yashima Flex and Yashica Flex B lens caps.
I have used photographs and articles, with permission, from a number of correspondents and these are acknowledged accordingly. Most of the remaining photographs are mine except where I needed to show critical detail and had nothing suitable available. In those cases, I have used photos found on the net and acknowledged that (generally from auctions that have ended and/or Japanese sites and therefore impossible to follow-up). I have not used complete images of items or displayed full serial numbers in order to maintain anonymity of owners and not devalue the possible worth of the original image itself. If I have upset anyone by doing so, please contact me with image details and some proof of ownership and I will take immediate steps to remove. My page is entirely non-commercial and therefore I am not seeking to derive any benefit from it other than expanding the knowledge base of Yashica TLRs. Hopefully, you will support me in this.
Karl F. Kahlau, author of the book “Collector's Pictoral Encyclopaedia & Value Guide to 6x6 TLR Cameras”, has very kindly allowed me to use material from his book and in particular, to both use and critique the Production List of Yashica 6x6 TLRs based on original Yashica/Kyocera information.
I recently came across a Japanese site, TLR66.com, at http://www.tlr66.com/souko/yashicaflex-miwake.php. It has an article about recognising Yashicaflex models. The site is not overly detailed and the Google translation is appalling but my conclusions seem to be in step with that site’s information. One mistake it does make though is to call the Yashicaflex AS-II a “Yashicaflex AS” and the Yashicaflex AS-I a “Yashicaflex AS-II” (I can see how that can happen, for example, if only relying on Yashica's “Yashicaflex Directions for Use Model A & C” - it confused me as well). Where there is conflict or I have relied on that site’s information, I have noted it.
Other sources including, Camera-wiki.org, are acknowledged where the material is referred to.
The draft of this site has been vetted by both Tom and Leigh and their input is gratefully appreciated.
Essentially, this site loosely follows a format of context setting, model identification, model naming and related historical and marketing considerations, camera bodies and 66 model trim changes, lenses, shutters, serial numbers, Sugiyama's influence, Yashicaflex A series complexities, trim and specification changes by individual model and serial number for 66 models, Yashica 44 series development, and finally, 44 model details. The Pigeonflex started it all and the change from Yashima to Shinano production is not so clear cut so I have added the "The Pigeon Loft" to explore these models further. Then there are also some prototypes and specials worth mentioning. I have included a page to consolidate access to brochures, the sort of thing that all of us like to peruse and which also support some of the claims on this site. To these I have added a page on lens caps, cases and boxes and other pages for accessories and more practical issues for anyone contemplating their first foray into Yashica TLR ownership. Finally, but not least, are profiles of the significant contributors to this site.
Because I become a little obsessive about things, you may find that what you thought was set in concrete one day, is subtly changed the next. I think about things, receive correspondence, find things on the net and find faults with my writing - it's a dynamic process. That only applies to the information. I'm under no illusions about the amount of traffic that sites such as this generate and therefore I am unlikely to want to spend time redesigning and adding bells and whistles. That is why I have attempted to keep the layout style simple. Like a book really. In order to keep everyone sane, I have belatedly added an “Updates Log” below.
There will be situations where I make changes to one section and forget to make changes to another corresponding section so that apparent contradictions will surface. Over time, I tend to find most of these but please feel free to remind me and point out any other mistakes.
Although not optimised for lower resolution devices, I have tried to keep things as friendly for all viewing resolutions as possible. Note that the site was developed on a 1920 x 1080 monitor. Most laptops display at less than that and in some cases, side by side images may end up one above the other.

The best way to keep everybody happy is to ask first, a reasonable request will almost certainly get a “yes” providing I have the rights to grant it.
This site went live on 16 November 2011. Since then, there have been numerous changes, most small but some bigger changes as well. I'm not going to get too pedantic with tracking changes, particularly small changes of detail such as additional serial numbers or colours found or pinning down some variation more precisely.
