Happy SUNday! – bluejeans and cameras

Happy Sunday everyone – I hope y’all are safe, happy, and with your families.

This was taken in early 2015 shortly after a walkabout with my Yashica Pentamatic S and Yashica 135mm lens. There’s nothing quite like an outing with a favorite camera (c. 1961) and an old pair of comfortable jeans (c. 1999).

Shot with my then Samsung Galaxy S4 in natural light. This pic was recently favored on my Flickr photostream by a visitor to my site. It reminds me that we leave a long electronic trail on the internet (so be careful what you post).

Yashica Pentamatic S – 1961

Yashica Pentamatic S with Auto Yashinon f/1.7 5.8cm lens made by Zunow (likely).

The Pentamatic S – the last 35mm SLR in the short-lived Pentamatic series. I believe that this rather odd lens was made by Zunow for Yashica and was sold exclusively on the Pentamatic II (Aug 1960 to Jan 1961). Here it’s pictured on the later model S. Most of the early Pentamatic bayonet mount lenses were made by Tomioka but a few were made by Kyoei Optical who was known for their Acall lenses.

Yashica Super Yashinon-R f/3.5 13.5cm Lens – Likely made for Yashica by Kyoei Optical

It’s come to my attention recently through correspondence with a reader of this blog that my Yashica lens may have been made for Yashica by a small lens maker, Kyoei Optical Company, Ltd.

I had assumed that most of Yashica’s early lenses were made by Tomioka Optical of Tokyo with only a few exceptions. Zunow made some cine lenses for Yashica in the late 1950s and it looks as though Zunow may have made the odd 5.8cm f/1.7 lens that was used on the Yashica Pentamatic II (August 1960 to January 1961) and the lens on the earliest Yashica Lynx 1000.

Pictured below is the subject of this post – my Yashica Super Yashinon-R f/3.5 13.5cm short telephoto lens with a Pentamatic bayonet mount. The lens is further marked with a “K.C. in red on the front lens ring. It’s a compact but heavy pre-set lens with click stops at f/3.5 to f/22.

My Yashica branded lens from 1960

Below is a similar-looking lens that I found while surfing on Flickr.

flickr kyoei 135mm

This image is used with kind permission by Mr. René Maly. You can visit his Flickr site by clicking here.

His lens is marked Kyoei Optical Acall f/3.5 135mm and is pictured with an Exakta mount while mine is for the Pentamatic bayonet mount (unique to the Yashica Pentamatic). The Yashica lens weighs 390 grams (13.7 oz.) without the lens caps and the Acall lens weighs 360 grams.

Pictured below is the complete set as I received it some years ago. The metal Yashica branded lens cap is 52mm and is felt-lined and fits the lens perfectly. The hood is unmarked and it simply screws into the filter threads on the front of the lens. I also have an unbranded Pentamatic mount plastic rear lens cap which is the only one in my collection. The Pentamatic family of 35mm SLRs were only sold with standard lenses attached. I’ve never seen just a body for sale in its original Yashica factory packaging.

yashica 135mm logo

The lens has 12 aperture blades which appear to be common to the Kyoei Acall lens in this focal length.

yashica 13.5 les kc logo

The serial number is NO. 1350927 which indicates that it’s a 135mm lens and it was number 927 made since the start of production. It’s unknown when the lens first went into production but some of the very first may have been made as early as December 1959 but more likely January and February 1960.

What’s interesting is that this lens has a red “K.C.” engraved on the lens ring while the Kyoei Acall lens does not. A big guess on my part, and at this point, it’s only a guess, is that it refers to the hard coating used on the glass surfaces. Typically the letter “C” is used to identify that a lens is coated (Canon uses “S.S.C.” for “Super Spectra Coated” as an example). The “K” in “K.C.” may identify that the coating is from Kyoei.

Here’s another image of the Kyoei Acall lens.

So there you have it. Based solely on observation on my part between the two lenses I’ve made the connection to Kyoei Optical. I haven’t seen written information or anything in a Yashica sales brochure that links the two companies together. If you have additional info about Kyoei Super-Acall lenses made for Yashica please share it with me. Kyoei Optical also appears to have made SLR lenses for Petri and they made a bunch of lenses using their own name for use on L39 (LTM) rangefinder bodies.

A rare Yashica Pentamatic II instruction booklet surfaces.

Every now and again something new turns up in our never-ending search for the complete history of the Yashica Pentamatic series of 35mm SLR cameras. The first model of the Pentamatic was dated (by serial number) in December 1959 and the last, the Pentamatic S ended in March 1962. In between the Pentamatic II had a short run from August 1960 to January 1961. Fewer than 26,000 Pentamatics were made (of all models) during its brief run which makes the Pentamatic one of the hardest to find models in Yashica’s historical line-up of SLR cameras.

A recent online auction featured this never before seen instruction booklet (below).

Yashica P2 book lolo

It’s not much to look at as the cover is devoid of any attempt to market the camera.

My best guess is that the booklet is an English edition of the Pentamatic II instructions. The Japanese edition (below) is much more in keeping with the style of the other books. My good friend and Yashica collaborator Paul Sokk and I agree that the Pentamatic II was never released for sale outside of Japan which makes the discovery of this white cover booklet for the Pentamatic II that much more interesting.

Front and back covers of the Pentamatic II instruction booklet. It’s the only manual found so far that’s printed in Japanese.

Here are all three of the instruction booklets for the Yashica Pentamatic (below).


Up to this point, these were the only known Pentamatic instruction booklets.


Here’s a scan of the first page inside the white covered booklet – pictured is a Pentamatic II with it’s Zunow sourced 5.8cm f/1.7 lens. The camera is still identified as the original Pentamatic in this image, however.

So the big question is why did Yashica print this instruction booklet in English when from all evidence the Pentamatic II wasn’t released for sale outside of Japan? A secondary question is why did they choose to not title the booklet as being for the Pentamatic II? Our best guess is that a few Pentamatic II models were in fact sold in Japan possibly in military exchanges and in duty-free shops and an English version was needed. It’s also possible that a few Pentamatic II’s were sold outside of Japan and the booklet was produced to supplement the camera. Nothing yet to prove that the Pentamatic II was sold outside of Japan but the existence of this book adds a new wrinkle to the history of this camera.

Thanks for stopping by and as always, if you have additional info about any of the three Pentamatic models please share it with us. Thanks, Chris

Time Capsule – 1960

Another look at this post from last year. New evidence shows that the Pentamatic (original model) was released in Japan in January 1960 but as of this reblog still no instruction booklets found printed in Japanese – only English. The Pentamatic made its first appearance in the US around March-April 1960 with the first ads appearing in May.

Yashica Pentamatic Fanatic

yashica pentamatic set The original Pentamatic.

A nice example of Yashica’s first 35mm SLR – the Pentamatic. Also known as the Pentamatic ’35’ in its earliest advertisements and sales brochures. This particular camera is from August 1960 – the same month that Yashica started production of the Pentamatic II – a model that was destined for the Japanese home market and not for world export. The Pentamatic II stayed in production only until January 1961 when it was replaced a few months later with the Pentamatic S. The original Pentamatic was first produced in December 1959 but widescale production didn’t begin until January 1960. As of this update (Oct 11, 2018), I still haven’t found evidence of an instruction booklet printed in Japanese – only English booklets so far. I would think that there must be booklets in Japanese and at least 2 or 3 other languages but none found. The Pentamatic II…

Pentamatic Microscope Adapter – 1960

I have yet to use a microscope adapter in nearly 50 years of 35mm photography – but that doesn’t mean that I haven’t collected them and enjoyed the thought of someday using one. I’ve had a few Canon adapters over the years too.

The first step would be actively looking for a microscope to purchase on one of the many online auction sites. Something I will do.

Here’s a nice adapter from Yashica with the Pentamatic bayonet mount. It’s one of the first accessories to appear in the early Pentamatic instruction booklets from 1960. List price was ¥2,500 which was fairly expensive back in the day.


The adapter mounts directly to the body of the camera – no lens needed.

These instructions are from a later booklet featuring the adapter for the M42 screw mount.



I believe that the microscope depicted here is a Yashima microscope but it’s not made by Yashica. Yashima was the first name that Yashica went by in the early 1950s.


Not made by Yashica but still a super cool vintage microscope.


Typically you’d use a right angle finder such as this one to make it a bit easier to use the adapter on a microscope.

What’s always amazed me is just how many different camera manufacturers made microscope adapters – Canon, Olympus, Nikon just to name a few and how many are still available for purchase online from various auction sites that are unused, still new in their boxes.

Nicca Pentamatic!?

Stay with us and we’ll try to make our case. Recently discovered information has filled-in some of the missing links in the development of our favorite obsession camera. The mysterious and seldom seen Pentamatic ’35’… Yashica’s first SLR.


A few interesting bits of info have come to our attention recently. We were alerted to an auction by our friend Paul Sokk (http://www.yashicatlr.com) that listed a 13.5 cm f/ 2.8 lens made by Taiho Optical Company –  Nicca Lens. Having never heard of the company, Taiho Optical, and knowing about Nicca’s history, we couldn’t figure out where and how there could be a Nicca connection.


Let’s backtrack a bit with a quick history lesson. Yashima-Yashica was a very successful maker of high quality, low-cost twin-lens reflex cameras but hadn’t moved into the 35 mm market as of early 1957. It appears that the president and founder of Yashima-Yashica, Mr. Yoshimasa Ushiyama could see that although Yashica was successful building TLRs, the market for them would slowly diminish as new, smaller and easier to use 35 mm cameras would grab the marketplace. He wanted in but how?

Yashica had no experience with 35 mm cameras, especially rangefinder cameras with cloth focal-plane shutters. There were dozens of Leica copy cameras in Japan (and the world for that matter) but possible patents protected specific manufacturer’s shutter designs. If he could buy into an established company then he could use their shutter design and incorporate it with early Yashima-Yashica designs. In May of 1958, an opportunity presented itself. Nicca Camera Company was apparently experiencing financial difficulties and may have been on the brink of bankruptcy. Nicca cameras were well known and well respected – they made high quality 35 mm rangefinder cameras with focal-plane shutters. They used Nikkor lenses with the L39 screw mount. Mr. Ushiyama was in a rush to purchase Nicca before they went belly up. Advisers cautioned to wait until Nicca went bankrupt arguing that they would be able to acquire it for a better price. Mr. Ushiyama knew that that outcome of a bankruptcy could take longer than he was willing to wait and there would certainly be more suitors to compete with. So the deal went through… sort of. As best as we can glean from our research, a “religionist” “admonished” Mr. Ushiyama for rushing into the deal and cautioned that Yashica itself would suffer a “decline” if all of the transfer were made immediately.


OK, OK! We give!!! We share your feelings dear reader –  what’s the connection between Nicca and the Pentamatic? Taking the advice of the religionist, Mr. Ushiyama created a new company. Nicca would become Taiho Optical Company. Say what? Nicca wasn’t absorbed into Yashica in May of 1958, instead, they became another company that could continue to operate with Yashica but without becoming Yashica. Simple. Confused? Mr. Ushiyama listened to his adviser so nothing bad happened. It appears that the former Nicca employees were now free to develop new processes and designs with the financial and technical support of the much larger Yashica. What did Yashica get for its money? Plenty it would seem. Access to years of 35 mm rangefinder manufacturing experience and access to a proven focal-plane shutter. Important steps in building a 35 mm single-lens reflex camera. We don’t know (yet) which one of the two companies came up with the design of what would become the Pentamatic. Was it mostly a Yashica design that had been kicking around for a while lacking a focal-plane shutter, or was it mostly a Nicca design that lacked the financial means to bring it to market? We feel that it was more than likely a 60 – 40 split with Nicca as the 60%. Just a hunch, no facts at the moment.

Earliest known sales brochure for the Pentamatic ’35’. The best guess is that it was printed in the Spring of 1960.

Yas inside P1 bro

A machine translation of this page from inside of the brochure states clearly that Nicca and Yashica developed the Pentamatic.


But what did the Taiho Optical Company make? Yashica didn’t make their own lenses, Tomioka Optical of Tokyo did. Was the former Nicca, now that it had become Taiho Optical, going to suddenly start making lenses? At the start of this blog, we mentioned that we were alerted to the existence of a 13.5 cm lens for sale with the Taiho Optical Company-Nicca Japan markings. Other than that, nothing.

So when did Mr. Ushiyama merge the two companies? He apparently listed to his adviser and waited eight long years before merging the two. From 1960 (when the Pentamatic was released) until 1968, when he not only made Yashica whole, but he also acquired long time lens supplier Tomioka Optical.

Now we know how the Pentamatic came to be and why it could be called the Nicca Pentamatic.

The Yashica Pentamatic – Our 8 Year Search – Some Conclusions & Wild Speculations

20171125_133916 (2)

Some Conclusions

The first Pentamatic was “born” in December 1959 but wasn’t available for sale in the U.S. until April 1960. The Pentamatic was Yashica’s first 35mm single-lens reflex camera and was designed with the help of technology obtained from Yashica’s acquisition of Nicca Camera in 1958 and with some involvement with designers from Zunow Optical in 1959. Of course, Yashica designers were involved too as well as collaboration with Tomioka Optical for the first lenses.

Below is a scan of what appears to be the first sales brochure for the Pentamatic found in Japanese. A machine translation of it proves that Yashica and Nicca designers worked together to jointly develop the camera over a 3-year period. The exact date of this brochure has not been established but it appears to be at least issued in the Spring of 1960. Many thanks to my good friend Paul Sokk for his efforts in researching the Pentamatic with me over the years. His fabulous site can be found at www.yashicatlr.com

Yas inside P1 bro

Below is a scan of the cover of that first sales brochure that features the new Pentamatic.

Yas Cover P1 bro (1)

The original Pentamatic was a failure. A beautiful, sleek and modern camera at a great price, but still a failure. A replacement for it (Pentamatic II) was released by September 1960 – just a few short months after the original Pentamatic debuted.

The Pentamatic and the Pentamatic II were both out of production by January 1961. The Pentamatic S didn’t appear until around April 1961. Little was significantly changed over the course of these 3 models during this short timeframe. The Pentamatic II and its one-off lens improved on its semi-automatic capabilities. The body stayed the same with the exception of adding the engraved “II” after the name. No logic to this as Yashica could have simply made the new lens available as an option to the original Pentamatic. There had to be another reason to call it the model II and it appears that there were some internal changes made to accommodate the new lens.

The standard lens that was available for the Pentamatic II was designed and built (quickly?) by Zunow vice Tomioka. Our best guess at this point.

The Pentamatic II was only available for sale in Japan.

The Pentamatic S essentially was the replacement for the original Pentamatic – not the Pentamatic II. The model S added a lug for attaching an accessory exposure meter that coupled to the shutter speed dial. The S also added a self-timer and the body got a redesign (the strap lugs were moved to the front and the shutter release button was no longer at a 45-degree angle).

The Instruction Booklets

The booklets have been an additional source of fun separate from the camera searches. The booklet for the original Pentamatic was relatively easy to find. The first Pentamatic saw about 16,000 units made so the booklet is much more available. The Pentamatic II booklet was the hardest to locate since only around 5,000 cameras were made. The Pentamatic S booklet is even rarer – only around 3,000 cameras produced.



Inside the booklets…




Wild Speculations

Wild Spec 1 – The first Pentamatic was not initially released in Japan. Yashica had a slow go with its early production so only a limited number were available for the April to June debut in the U.S. There were only about 4,000 cameras made by then and that just didn’t support a wide release of it in their home market. However, with the discovery of the as yet undated sales brochure found by my friend Paul Sokk it does appear that some of the first Pentamatics were in fact distributed in Japan. We do feel that Yashica had a suspicion that the original model would not go over well at home. Why do we feel this way? During our quest of all things Pentamatic, we’ve yet to find an instruction booklet for the original Pentamatic in Japanese (or any other language besides English). We’ve seen no early 1960s advertisements either. Although we’ve yet to find these items that does not mean they don’t exist.

Wild Spec 2 – The Pentamatic II was only available in Japan and was never intended for widespread availability in the world marketplace. We further feel that the Pentamatic II was the camera Yashica intended to release in Japan vice the original Pentamatic. Why? Same thing… in over 8 years of searching, we’ve never seen a Pentamatic II instruction booklet in English and the only sales brochures we have are in Japanese. No English ads or brochures anywhere (yet). Update: As of April 2019 still no English ads or books.

Wild Spec 3 – The Pentamatic S wasn’t available in Japan. Crazy right? The same thing applies here – no Japanese advertising or brochures and no instruction booklets in anything but English. Again, not finding them does not translate to not being produced but the likelihood looks slim.

Wild Spec 4 – As we stated in the conclusions section above, the standard lens for the Pentamatic II (5.8cm f/1.7) was made for Yashica by Zunow Optical vice Tomioka. This flies in the face of what’s known and we don’t have solid written proof (yet, if ever). Both the original Pentamatic and the Pentamatic II ended production in January 1961. By coincidence, that’s the reported date of Yashica’s acquisition of Zunow (or their bankruptcy). Once Zunow went bust they no longer make lenses for the Pentamatic II.

Wild Spec 5 – Once the Pentamatic II stopped production, Yashica started selling the original Pentamatic in Japan (or at least increased its availability in Japan). We would still like to find a Pentamatic instruction booklet in Japanese to validate this thought.

Wild Spec 6 – Since the Pentamatic S wasn’t sold in Japan, there was a rather large gap in Yashica’s SLR availability. The next camera to be sold widely in Japan (and the U.S.) was the Penta J but that didn’t come out until the Summer of 1961.

These marketing and production missteps led to a less than stellar debut for Yashica in the world of 35mm SLRs. The competition during this same period was “inventing” much more sophisticated (and mostly more expensive) cameras which had a wider range of interchangeable lenses and accessories. It took Yashica a long time to establish a “foot in the door” with their Penta J and their first internally coupled exposure metered SLR, the Yashica J-3 (Jaguar).

Things we would like to find…


The first thing we would like to discover would be an ad, sales brochure or instruction booklet in English for the Pentamatic II. We don’t think we will as we feel that they don’t exist.

We would like to find a Pentamatic instruction booklet in Japanese. They must exist but we’ve yet to find one.

Pentamatic S instruction booklet and a sales brochure in Japanese. Don’t think they exist but time will tell.

Pentamatic II box!!! They must exist – someone’s got to have one in their collection! Update: Finally found one but we missed acquiring it for our collection so we “borrowed” this image –

***Solid proof that the standard lens for the Pentamatic II was made by Zunow Optical.***
