Cosina CT-1, die generische SLR


In a special way Cosina's CT-1 from 1979 is an outstanding camera and should not be missing in any serious SLR collection. It is the distillate from 4 decades SLR development and combines all those components, materials and design features that have prevailed during this period compared to their respective competitors. In a word, the GENERIC SLR.
It has all the essential features that one expected from an SLR at the end of the '70ies'. Also all the controls are where they are susposed to be. At the same time it has nothing special. The camera actually does not have anything that would not have been tried and optimized on other camera models already .
Cosina started as an optical factory and did not enter the scene of the camera producers until 1973, at a time when others just gave in (especially the German camera industry, but also Japanese companies like Topcon , Miranda and others that no one knows anymore today). The Kobayashi family started with (also generic) M42 models and copied the best features from the respective competition. Consequently, they changed in 1978 to the Pentax K-bayonet (public doamain), which many at the time believed to become the generally accepted industry standard. With these generic cameras the Cosina people quickly found their destiny: As a small, flexible and independent producer they offered to build cameras for international distributors, using their brand names (first coup). The list of cameras that Cosina produced under different names is quite long and the vast majority are based on this CT-1 base model. Over time, a faster shutter (Copal, up to 1/2000 s) was used. The basic principle remained the same and can be detected best by the arrangement of the three charakteristic controls: quick-release lever, trigger and shutter speed dial.
As the era of classical SLR's from the late 1980s has been replaced by the new AF generation, the major camera manufacturers decided to keep at least one classical model in the portfolio, to support the old range of non AF-lenses a little longer. Therefore they looked for a contract manufacturer for the cameras and found: Cosina (second coup). It happens that Nikon FE10 / FM10 , Canon T60 , Olympus OM2000  and others all can be technically traced back to the CT-1 and do not have much more in common with their brand sisters than the respective bayonet and the name on the prism. Pentax and Minolta chose another path and moved their old production tools to China and produced cameras like the K-1000 and X-370th over there. The K-1000 is a way with an almost identical specification the closest competitor to Cosina's CT-1 and its twin sisters.
Cosina's third coup and the reason why they still exist as a manufacturer of mechanical cameras in the age of digital photography, is the story around Voigtländer (I had mentioned it here before).  In 1999 they acquired partially the name rights for the oldest photo brand of the world. On the basis of the CT-1 Chassis they presented manual rangefinder cameras to take on Leica's M series. Cosina's assumption probably was correct that manual film cameras can only survive in one (and exactly this) niche during the digital photo revolution. Even Carl Zeiss jumped on the train and offered its own, supposedly better quality rangefinder camera. Please guess who produced it on Zeiss' behalf: Cosina! Also, for a short time there was a Voigtlander Bessa Flex SLR with M42 thread, again the CT-1 was its basis. 
And here is a personal story to the camera. In May 1982, when I bought my very first SLR (Nikon EM ) also my then best friend bought his SLR equipment: a Vivitar XV-1 (exactly: a foreign brand CT-1) and from the beginning with an extra wide angle and a telephoto lens. Of course I was jealous of the extra lenses he could afford, but even at the time I wouldn't buy such a "cheap brand". And somehow cheaply built they are. Although my 'new' CT-1 here is still working after 35 years (it was probably not used at all) it just feels less valuable than most other SLRs I have in my collection. Look at the body only weighing 420 g (compare my Nikon FT3 from 1977: 750g!). Still, I was glad to get a CT-1 in this condition, it is in fact not as easy as one might think.

  1. Nice to read this story. The other day I bought a Vivitar XV-1 body for 10 euro's and I use my Pentax K lenses again (the camera, a Pentax KX is not working rightly). Funny, I can hardly find any information about the Vivitar XV-1 on the internet and what I find says it is a shit camera. Well, mine is working. Fine I like simplicity of it. Best regards, Gerrit Brand, Netherlands

  2. Yes that's what fanboys tell about cameras they don't find sexy.
    Like e.g. the Pentax P30. This is a camera that does its job excellently but just isn't sexy, overall plastic coating, plastic winder lever, plastic time wheel etc.
    That's what makes stupid people say "it's a shitty camera".
    Imagine "Canon" or "Nikon" written on the Vivitar (or Cosina) body in big letters.
    Anybody dare calling it a "shitty camera" then?
    And yeah, 10€ is a great bargain for an SLR that works and gets the shit done.
    Congratulation!
