Hello and Welcome! Update 2.2.2017

Welcome to our blog about a very simple camera made by a company in Japan. We (Carol and Chris) are “Yashica Fanatics”, so it was a natural for us to start this blog dedicated to one of Yashica’s least known cameras. Most film camera aficionados might have some basic knowledge of the Pentamatic. They may have seen it in passing… usually fuzzy images on the web with often misleading info to boot. It’s a rather odd looking SLR with just enough quirks to make it interesting (to us at least). It was never a big time seller for Yashica but its true value was as a platform for innovation and invention for the designers at Yashica.

We fell in love with the Pentamatic’s clean lines and “modern” design. The presentation box was as unique as the camera itself.

Our “goal” here at the ‘Yashica Pentamatic Fanatic’ is to expose as many people as we can to the Pentamatic and to the company that conceived it. Please feel free to add to our knowledge base… if something is incorrect please let us know. If you know something about it or any of the topics we blog about… once again, please share it! We would love to here from you!

Another goal is to share our passion for photography. It’s been a part of our daily lives since we were born. I can’t remember the first picture that I ever shot – it probably was a mess – but I can remember one of the most special pictures I ever took – a picture of my parents.

My mom Mary and me in of all places, Vegas. We were on a big family vacation from New York to California – Christmas 1960. My dad Paul took this picture. Yep, my first camera – a Kodak for Christmas (notice that I was holding it up to show it off). My mom was holding a freshly taken Polaroid from my dad’s Pathfinder 110 Polaroid. Pictures – cameras – family.

Many many thanks for your visit… Chris and Carol ^.^

Yashica Pentamatic Lenses – Update 8.27.2017

Chris and Carol 9 Comments

As Yashica was designing their first 35mm single-lens reflex camera during the Summer of 1959 (with help more than likely from the newly acquired Nicca Company) they faced another challenge… since it was decided to use an exclusive lens mounting system (Pentamatic bayonet mount) and not go with the more common M42 screw-in mount, they put Tomioka Optical Company in a bit of a spot.

Tomioka was their exclusive lens supplier through the 1950s but Tomioka also supplied a wide variety of lenses to other manufacturers as well. That meant that Tomioka would have to start building a new lens series with an exclusive mount very quickly in order to have enough lenses available to meet the demands of a new camera hitting the marketplace by the Spring of 1960.

Here is but a small collection of Pentamatic lenses that were available in the early 1960 time period.

020

One of the earliest examples in our collection of the standard lens supplied with the Pentamatic ’35’ starting in 1959. We interpret the serial number to read: 1959, December and the 1,630th lens made by Tomioka.

017

This lens is the standard lens for the Pentamatic II which came out in August 1960 (Yashica was still building and selling the Pentamatic I at that time. It was a rather odd lens to use as the normal focal length… 5.8cm (58mm) but with a slightly faster f/ 1.7 aperture.

018

Front view of the standard lens for the Pentamatic II. It is a very beautiful lens and it does provide a bright clear view wide open. Here it’s mounted on the Pentamatic I.

011

One of the earliest medium telephoto lenses for the Pentamatic. We don’t know what the ‘K.C.’ stands for… our guess would be that it applies to the coating on the surface of the lens. The serial number decodes to 135mm and the 927th made in the production run. We feel that this lens was made in 1959.

005

Original lens shade (as Yashica calls them) from the early days of production. The lens is the standard f/ 1.8 5.5cm lens for the Pentamatic I and S. From about mid year 1960.

003

A highly desirable early Tomioka branded lens for the Pentamatic. Another issue from 1959… the serial number 35 = 35mm and 246 indicates the production sequence. This lens is super bright and sharp. An excellent wide-angle lens for general photography.

008

The latest lens of the original production run that we now have is No. 60521000. The lens (above) shows that it is number 15,001 in the run which would put the lens into early 1961 production. 

We hope to expand on more details of the early Pentamatic lenses in the near future. Stay tuned and thanks for reading our little blog!
