Early Mamiya Prismat with curved nameplate: lucking into rare
So there was this guy offering a 1960 Mamiya Prismat 35mm SLR camera for sale on Kijiji, asking for offers while claiming that the item usually went for $200-$600 in online auctions. Since I knew next to nothing about Mamiya, I jumped into Google but couldn't find any of those auctions. Similar Mamiya cameras were going for $55-$100, so I offered this guy something along those lines and – after a brief negotiation – we agreed to meet up. In my mind, it was obvious that he had been bluffing about the going prices.
A brief inspection showed that the camera was in pretty good cosmetic condition (as advertised) and looked really cool. Included in the package was also the original protective leather case! So I took the camera home, feeling good about the purchase. I had some questions about it, so I tried to contact the seller by email, a few times, but to my surprise he never replied... Suddenly, I wasn't sure if the price I had paid was right or if there was anything wrong with the camera.
So I went online again to try and find more information on the new acquisition. The seller had said that this was a Mamiya Prismat, but the word "Prismat" was nowhere to be found on the body. None of the many photos of Prismats that Google was showing seemed to match my new camera... until I finally found a matching photo that led me to Ron Herron's excellent Collecting Mamiya 35mm site. From the site's Prismat page:
"The Mamiya Prismat NP, released in February 1961, was Mamiya's first production single-lens reflex (SLR) 35mm. The very first Prismat is readily identifiable by its distinctive curved nameplate on the front of the prism housing. It was soon updated to the more familiar rectangular Mamiya nameplate".
It seems that Mamiya had been developing what would be its first 35mm SLR since 1952, designing prototypes of different cameras that never made it into the market. My camera, known simply as the "Mamiya Prismat" or "early Mamiya Prismat", hit the market in 1960 and was Mamiya's first official 35mm SLR. Ron Herron says that records of the number of units of this camera produced are not available, not even from Mamiya. By early 1961 it had been replaced by the more well-known version – the Mamiya Prismat NP mentioned above.
"It has no meter, and its available lenses featured a semi-automatic aperture with an external Exakta-type linkage (actually introduced by Ihagee) for aperture function. The known Mamiya-Sekor F.C. lenses include a 35mm f/2.8; a 48mm f/2.8; a 58mm f/1.7; and a 135mm f/2.8. There was also a 50mm f/1.9 available, made by Canon."
[Quick pause for a fun tidbit found here: "At the same time that Canon was making this lens for the Mamiya Prismat (something not ever mentioned in the Canon official history that I can find), Mamiya was also collaborating with Nikon to make a "consumer grade" camera called the Nikkorex. This is the "lost camera" also for Nikon, since it does not exist, really, in their official histories."]
My camera came with the fastest of the available lenses – the Mamiya-Sekor 58mm f/1.7. The lens rim has a few scratches. Other than that, and apart from some resilient dust particles on both the front and back elements, the lens looks OK. It's a bayonet-mount lens, with apertures ranging from f/1.7 to f/22.
Regarding the "external Exakta-type linkage" of this lens: there is an "outrigger" to the left of the barrel (visible on the very first two photos of this blog entry, above). When the camera's shutter is depressed, a "shaft" protrudes from the body to this outrigger, causing the lens to stop down to the set aperture.
"There is a lever on the lens that must be turned to open the aperture for viewing. The aperture then closes down to take the photo. It remains at that aperture until you turn the lever on the lens again to view it at full aperture. It is hence not an "automatic" lens."
The film-record dial (above, the one on the left, around the rewind crank) allows you to set the ISO rating of the film that's inside the camera. In addition, a dial on the back lets you select the number of exposures of the film cartridge, colour-coded depending on the type of film (colour, black and white, infrared), plus two other settings ("sp." and "EMP.", for empty). The exposure-counter dial appears within the stylish film-wind lever, and the shutter release within the shutter-speed dial.
To open the camera back and access the film compartment, you have to follow three steps: first, unlock it using the lock found at the bottom (see the second photo after this paragraph); then, pull out the rewind crank; and finally, open the compartment by pressing the back latches on the side of the camera. Note the cloth focal-plane shutter below.
There's a small lever (seen under the lens, to the right in the image above) that needs to be depressed in order to unlock the lens and allow for it to be removed.
The serial number on my camera is 3346509. In seven years since this blog entry, I've been able to find only four other serial numbers of this model on the internet, and three more through emails sent to me by readers of this blog: 3345939, 3346018, 3346101, 3360082, 3360242, 3360324, and 3360497. This could be just a coincidence, but it might also mean that there were only three series of 1,000 cameras made (3345xxx, 3346xxx and 3360xxx), which would be an indication of just how limited the production of this early Mamiya Prismat really was (and would also explain why so few of them are showing up on the internet today). If you have one of these and want to share the serial number, please contact me.
Everything in the camera seems to work well, and I might even try it out with a roll of film. The question I need to answer is, should I keep or should I sell? For now, it's not going anywhere.

Yes, no need to sell D700 if you have trouble with sensor size and "mm" conversion. What I use for wide on my APSC (Fuji XT1) is brand new Fujinon XF 14mm 2.8. now I will sell it and buy 16mm 1.4 that is coming out soon. Fujinon went a step forward with lenses line and at the moment they really have quality as Zeiss or Nikon or Canon.
But as for manual focus lenses, wide is not option for me. I use only portrait size manual focus lenses. Simply new modern wide XF Fujinons are a mile ahead of old wides. For portrait Fuji made new automatic XF lens 56mm f1.2. That is on my list too. I am selling some old lenses I hope I will save some cash. Anyway, in all lenses brands I find somethinig good about it. I love Canon's colors, but for example I have a 55mm 1.2 SC Nikkor and that is my best portrait lens, even it is rather soft in center wide open.
Back to Mamiya F.C. 58mm 1.7, there is one I found it could be for sale. I don't sell mine ever because no other lens gave me such imaging, not even Planar Zeiss... But my work coleague's father passed away and left one Mamiya F.C. behind. It is attached to Tower 32B. The thing is he does not know the price and how to find out the value if there is no such lenses on the market?
I very often shoot at 14-16mm. If that can be replicated with an APSC sensor, then I might be interested. The optical quality of the lens would need to be similar to the Nikon 14-24mm. I don't think that's currently the case, though.
I'm in no rush to make the switch though. One day I will replace my DSLR, but for the time being the D700 gives me all the performance I need and then some.
Also, the more I read about Mamiya lenses, i think this 58mm FC 1.7 is their gem of that time, and time after that! I don't see any other better lenses that that one by reviews. The looks, materials... simply a gem! Since there is no available information and enough users of this lens, it makes it even more mystic. How come there is no more of them? How come its quality was ignored over the years? Strange.
the DOPF that I can get with FC 58mm 1.7 is liek DOF that most lenses get only at 1.2f or 1.4... Amazing lens. Simply that is why is a keeper.
Full Frame and mirrorless, hm hm, the technology wins over the sensor size and it not as important as before. Sensor size is becoming second most important in the camera body. The tech behind, and what is in the sensor matters and those are the micro lenses that give light more than ever before. I read a lot, and I easily decided to buy APSC. You have to chewck photos that XF 10-24mm does... You notr gonna miss any width :) And colors, hm not many can beat Fujinon today. I sold my Nikon D700 immediatelly after testing FujifilmXT1. I was hard-on believer in FF. And now I am convinced it really doesnt matter anymore.
