Mark's Kowa SET R2 Page2-5-23: Bought at Goodwill online auction for around $13 bucks. 1968 to 1972. The company quit the camera business in 1974. It uses 35mm film. Mine came with a Kowa 50mm f/1.8 Lens. It uses a Kowa type R lens mount, and I'm pretty sure nothing else will adapt to it. It's a historic camera, as I've found it uses a leaf shutter mounted behind the lens ON the lens mount. I've read these are incredibly complicated and few are found still working. I think this is why this group of 5 otherwise unimportant cameras got bid up a little higher. It sold for around $155 new, maybe $1000 in today's money. Can't wait to see if it still works. Either way, it's weird and historic so I will add it to my collection.
2-11-23: Received in good condition, I think even the shutter works. Front of lens is wobbly, might give it a film test anyway. Pic below is as I received it.
