The Pentamatic S… the last true Pentamatic in the short lived series of SLRs from Yashica. The Pentamatic II is the hardest to find from a collector’s standpoint with the S close behind.
In the above pictured Pentamatic S, the serial number is NO. 140572. Our other S is NO. 140294. We believe these numbers decode to… 1=1961, 4=UNK, and the last three digits equal the sequential production numbers. The S models were not produced in great numbers so it is possible that both of these cameras were made during the same month as they are within 300 units of one another. One other serial number in our database is… NO. 141796 which suggests that it was the 1,796 th unit made later in 1961. Interestingly the serial number of the model S in Yashica’s instruction booklet is NO. 140893. It is odd that the camera in the booklet has a higher production number than two cameras we own.
In summary… the S is a very worthy camera and is built like a tank. The S went back to using the Auto Yashinon f/1.8 5.5cm lens which is a good thing. The Tomioka Optical built lens is sharp and smooth. The S allows for the attachment of a separate exposure meter on the front lug (where the “S” is) and can couple with the shutter speed dial. Still a long way from TTL metering but at least headed that way.
