As so often happens when you eBay recklessly I bid on and won another new lens. I always follow auctions of Sears/ Tower/Montgomery Wards camera equipment as most of it is just rebadged equipment by major manufacturers and since nobody else bids I get good equipment dirt cheap. Problem is this time I bid on both a Tower 37 SLR and assuming the seller's other lens went with the camera I bid on it too. Got home too late to snipe the camera (oops) but found I'd won the lens. When it arrived I found a nice Mamiya-Sekor FC f1.7 58mm w/Exakta style mount (#900116) which according to Ron's excellent site (Thank you Sir) means I now need to add one more body/lens system to my collection, a Mamiya Prismat or Tower 32. Ahhh, the perils of ebidding without research first LOL. Anyhow, just had to relate and tease Ron as it looks mint with original front and back caps and smooooth semi-automatic diaphragm.

Curt, that "Exakta-style" mount could be for a Topcon. Some of their bodies used them.

Hi Walker,
Yes, some Topcons used Exakta mount. I believe the Super D did for sure and probably others. I have a 135 f2.8 that is Topcon mount I bought specifically for one of my Exakta cameras and for some reason it doesn't fit either. If I remember properly it has an extra pin of some sort.
The lens I bought uses the Exakta mount but the pin to fire the lens is on the wrong side of the body and fires via a pin coming out from the camera body rather than depressing the pin on the lens like an Exakta. Definitely Mamiya Prismat, now the search begins for a body.....

Curt: The Tower 37 is a rebranded Mamiya Prismat PH, which was also sold as the Prismat PCA V-90 by Photronic Corporation of America. If you're trying to avoid having to get lenses with different mounts, you should be glad you didn't win the Tower 37, because it is a TOTALLY different mount from the Prismat NP (the one with the Exacta-style mount, also found on the re-badged Sears 32A and later the Tower 32B and Sears 32B). A version of the NP with a vertical-travel, metal focal plane shutter was also sold as the Sears SLII. An NP version was also marketed in the UK in the very early 60s as the Mamiya Prismatic, or the Mamiya Reflexa.  The only Mamiya I would sit home and cry over missing out on (since it's one of the few I don't have) is the original Mamiya Prismat, with the curved nameplate. I've only seen it once in an eBay auction...and the starting price was $500 -- far too rich for me. I couldn't sell enough of my other duplicates fast enough to let me go after it!    |

Hi Ron,
Thanks for the info. Yep, looks like I'll need to search for a Prismat NP or a Tower/Sears 32 B. And then that's it, no more lens mount systems, well unless I find another cool old lens pretty durn cheap, LOL.

Curt: The same Exacta-mount lenses would have been used on all the Prismat NP versions...although I think the ones sold in the UK had Canon lenses with the Exacta mount more often than the Mamiya lenses. Don't have a clue as to why. |

Have you got an Exacta Ron? Worth a go, even with stop down aperture. And they are cheaper over there!
Regards - John

Regards - John No Exacta...just several Mamiya Prismat's with the Exacta mount -- in both Mamiya and Canon lenses. I've bid on a couple of Exacta's over the years, but they always seem to get out of reach (or I miss out on the ones that stay reasonable).  |
