Yashicamat, Yashica-Mat, YashicaMat – they’re all the same camera, and as was typical for Yashima (later Yashica) they had a difficult time staying consistent when it came to the way they named their cameras. At this point in time, Yashima had only been around since 1953 so I’ll cut them some slack. By 1958, Yashima became Yashica as the company adopted the name of its cameras.
So here is a super early sales brochure (Spring 1957) for the new YashicaMat 120 roll film twin-lens reflex (TLR) camera, the YashicaMat.
High-res scans are posted below from my own brochure.

Front cover.
What I find interesting is that the camera that’s depicted is the very first version of the model with a 75mm Lumaxar f3.5 taking lens (bottom lens) that were only available for a very short time before being replaced by the lens described in the brochure – 80mm Lumaxar f3.5 lens. There’s no written history to definitively know why the change was made so quickly or why they switched at all. It’s possible Tomioka Optical had difficulty providing enough 75mm lenses to meet the production demands of Yashima.

If you look closely at this back cover you can see Yashima’s full corporate name – Yashima Optical Industries, Company, Limited, and their headquarters were located in Shibuya in Tokyo. The factory was in Suwa, Nagano Prefecture, and later Shimosuwa.

Thanks for stopping by and if you chase down a nice Yashica-Mat that you like be sure to check out my good friend Paul Sokk’s excellent TLR site at http://www.yashicatlr.com to learn more about the camera that you’re about to purchase. – Chris
