Yashica Penta J and the J-P

Yashica’s first 35mm single-lens reflex camera with the Praktica-thread (M42) mount lenses was the Yashica Penta J… at least here in the United States and in Japan. Elsewhere (most of the world) the camera was known as either the Yashica Reflex 35 or Reflex J (Australia and possibly the U.K.). As best we can tell, they were all the same cameras with different top plates to accommodate the different names (logos).

Part of the demise (lack of sales success) of the well-built Pentamatic series of cameras that preceded the Penta J, was that Yashica decided to go with a Pentamatic exclusive bayonet mount lens system. Sturdy and well designed to be sure, but being unique limited the available lenses that could be swapped between cameras. The Praktica design M42 screw thread mounting system was in widespread use at the time and Yashica’s bayonet design just went against the flow.

Now fast forward to 1965 ish… Yashica introduces the new J-5 AND the J-P! In between those years Yashica had introduced the J-3 and J-4. Why would Yashica go back in time and bring out another 35mm SLR in 1965 that was the cousin to the 1961 Penta J? Notice we say cousins… not brothers. They shared the same platform with one another but as you can see in the image below the top plates were of a different design.
