I bought this Pentamatic last year, unfortunately without a lens. A week later I picked up a T mount, which enabled me to fit a preset 135mm lens, and use the camera, once I had replaced a broken shutter tape.
The Pentamatic was Yashica's first SLR, released in 1960. It comes with a unique bayonet mount, instant return mirror, and a Praktica-like shutter release. The film counter is reset manually, and the standard lens has a semi-automatic diaphragm, not reopening until the shutter is cocked. Initially the other lenses supplied (35mm, and a range of telephotos to 250mm) were preset diaphragm. There were adapters to allow the use of Pentax/Praktica, and Exakta lenses.
The back is opened by pulling up the rewind lever, but only after turning the lever seen here from "A" to "O". The intermediate "R" position pops up the spring loaded rewind lever and allows it to turn, but keeps the back locked.
I tried out the camera with the Safari brand 135mm T mount lens. Here is a shot of my town's partly built medical centre.
There was a Pentamatic II released in 1961, which had a fully automatic diaphragm mechanism, and there was supposedly also a Pentamatic S, which had a delayed action fitted. In 1964, Yashica changed to a lens system with Praktica thread (But which had the Edixa lens register). The cameras in this range have fewer features than the Pentamatics.
Thanks for posting the photos and description of Yashica's first SLR. I have a soft spot for Yashicas as I started with a 230AF and older ones are no too common around here. The Pentamatic is an interesting camera with enough quirks to satisfy any collector.

I bought the adapter (which was unused) from the same seller as the camera, along with assorted bits and pieces, John. I bought the camera, hoping to pick up a lens later - I have a saved search on the auction site - but no pentamatic gear has been listed since August last. Oh well, one day.......

Hi John, I'm curious if your search is limited to eBay in New Zealand since I've seen and bid on at least three Penta/Pentamatics in the last year or so. I have a very rough Yashica Penta J that came with a mirror that sticks every 5-6 shots, slow speeds NFG and missing the rewind stem and knob. Came with a Zeiss Jena Tessar 50 f2.8 which also has the actuator pin stuck in but works in manual on f2 and f4 only then jams. I've seen and bid on a few Yashica JP which may be a relative?? as well as the 2-J5's, J7 and J3 that I use. I have both the semi automatic diaphragm lenses made by Pentax and Yashica. Luckily enough they both still work great. Even have a semi automatic diaphragm Mamiya for Mamiya/Tower SLR. All neat old technology but I've yet to buy a functional Penta/Pentamatic.

Its a strange thing about one or two Yashica models, you can't find out very much about them! My first camera was the 35J - a rangefinder with a blocky type body. Definitely not your 35J Reflex! I bought a Yashica J, thinking to recreate my first purchase, but it isn't even close. No info for the 35J Rangefinder. Then too, the 'M'. Can't find any documentation for that either. No typical Yashica 'Letter' logo at the top, just a stick-on label (although obviously original) at the bottom left, by the 'X' PC socket. Came with two very nice Accura extensions for that, but the original owner must have played by sense of smell, as there are no markings in the viewfinder for them!
Regards - John I have to admit that I hadn't heard of the Pentamatic before your post

Hi John It's a curious thing, I can't even find the 35 J in the Collector's Guide To Japanese Cameras but I can find a Konica J and a Samoca 35 J. Seems every country exported to had their own designation for some cameras. If you had a picture maybe I could help. Here's the two Yashicas you mentioned, identical in every way down to the last screw and the indentation for the name Minister or Yashica M. Identical EXCEPT for one thing, the Yashica M uses a 45mm Yashinon f1.9 (yes, I looked thru a magnifier and it's 1.9) while the Minister uses a 45 mm Yashinon f2.8. Otherwise they're identical. Just wish I could find a Yashica 35 J photo.
