Very early if not the earliest printed in the US sales brochure for the new Pentamatic.
We’re thinking the summer of 1960…
We haven’t found an earlier brochure that features the Pentamatic then this one – “Printed in the U.S.A.” on the back cover using the 234 Fifth Avenue, New York 1, N.Y. address. The cover is amazing in that other than Yashica’s name and an image of the camera, there’s no other writing. No “Pentamatic” – just an image of the camera. That was a first for Yashica as best as we can tell.
The first magazine advertisement was June 1960 in the US so we don’t believe this brochure was out before that. The only problem with our thinking is that most of the other cameras featured inside this brochure are 1959 model cameras and in some cases late 1958. There could even be a few that came out in early 1960. The two pages we’ve scanned (see below) contain an interesting wealth of info on the features and accessories for the Pentamatic. Of note, the lens serial number (No. 59100036) puts that lens to be one of the first lenses Tomioka made for Yashica with the new Pentamatic exclusive bayonet mount – 59 = 1959, 10 = October, 0036 = the 36th made in the production run.
We know from our research that the October 1959 date for the lens is 2 full months early from the first Pentamatic bodies (December 1960). Our best guess is that Tomioka Optical (the maker of the lens) needed to start production of the standard lens early in order to meet the demand for the camera body itself. No proof exists yet but it’s the best decoding of the lens serial number we can come up.

Page 2 shows (with prices) a nice selection of accessories for the Pentamatic. It appears that at the time of this brochure that there were 5 lenses available in the Pentamatic bayonet mount.


























The beautiful, simple and clean lines of Yashica’s first SLR.
Decoding serial numbers… Yashica has never been upfront with the dating of their cameras, lenses or printed materials. Instruction booklets and sales brochures are only occasionally dated and those were mostly in the 1950s and then again in the 1970s. Camera bodies and lenses (and accessories) remained a mystery until now. We believe we’ve finally decoded the serial numbers of Yashica’s first 35mm SLR, the Pentamatic. Look closely at this camera’s serial number… 16000375… knowing a little bit about when this camera was “invented” helped us decode the number. The trademark “Pentamatic” was filed by Yashica in September 1959 in Japan. The first lenses were built in October 1959 with the first bodies produced by December 1959. This camera (above) dates… 1 = January / 60 = 1960 / 00375 = 375th unit made since December 1959. The latest camera in our database has a serial number of 16115756. This decodes to… January 1961 and was the 15,756th unit produced since December of 1959.
This Pentamatic body (above) decodes to… 3 = March / 60 = 1960 / 01500 = 1,500th made up to that point.
