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.
