That date* might be a bit misleading as the sales brochure this was scanned from is undated (as is most Yashica marketing stuff). Our only clue as to the date is that it (the brochure) features the newly released J-3 and doesn’t include any other Yashica SLR. No Penta J or Reflex 35 (same camera different markets) and no J-5.
We like it because it features the Yashinon lenses available at that time. If you look closely at the mounts of the lenses, you’ll see the M42 screw-in mount. Yashica does state in the brochure that all of these lenses are available in both the Yashica Pentamatic bayonet mount and the M42 mount. My friend Paul, see An Interview with Paul Sokk – Site Author of the popular YashicaTLR.com , has proposed that Yashica may have distributed these lenses to dealers (market dependent) with both mounts – meaning that they were shipped with the “new to Yashica” M42 mounts but could be converted easily at the dealer level to bayonet mounts for the Pentamatic. Sounds very possible. At this time, Yashica also sold adapter rings for mounting their M42 lenses to Exakta mount bodies and for mounting Praktica mount (M42) lenses to their Pentamatics. Confusing? Yes. Yashica guessed incorrectly when they choose to design their own bayonet mount for the Pentamatic back in 1959. Was it Yashica or was it Tomioka’s designers? How about the ex Nicca and Zunow designers? We may never know but it doomed the Pentamatic right out of the gate.
It is generally believed that all of these lenses were made by Tomioka Optical of Tokyo.
While some early Pentamatic bayonet mount lenses bear the Tomioka and sometimes Tominon names, most only carry Yashica and Yashinon. The same applies to the M42 mount lenses. Some can be found with Tominon but most simply have Yashinon. We don’t have positive proof that some lenses (both types) may have been made by another lens manufacturer. But whom? Taiho Optical (which was the former Nicca Camera hidden away in Suwa) but was really Yashica, or or or. We just don’t know. Pure speculation to think that another company did, but then again, no proof that there wasn’t another maker.
Thanks so much for your visit! If you made it this far you just may be a “Yashicaphile” or just Yashica junkies like us. Do you have something to contribute??? We’d love to hear from you and would love to include your info in our blog. Thanks! ^.^
