Below are photographs of original technical drawings, from the FED Zavod, of the FED 6 TTL rangefinder camera. These photographs were sent by e-mail to me, just as you see them, when I bought two examples of the FED 6 TTL camera (lens serial #9200003 & #9200001) from a Ukrainian camera dealer located in Kharkov (where the FED factory is located). I was told that these documents were original, and I have no doubt about that, as you can see various official stamps on them and the technical quality of the drawings are quite high.

Some of the photographs are quite good and a few are of poor quality, but I have included them all. I have not translated the text (I don't know much Russian) and will welcome any translations (full or partial) I receive and will add them to this page

Please also take a look at the bottom of the page as I have added some interesting information about the FED 6 TTL camera, collected from different sources. More comments and info is always welcome.

INFORMATION FROM VARIOUS SOURCES

from: http://www.russianplaza.com/FED-1-2-3-4-5-C-page2.html

"A FED 6 TTL was planned and introduced at the International German Photo Expo in 2000 but it was never put into production.

FED 6 TTL was to have an electonic shutter similar to the Minolta Leica CL. TTL metering system is a diode system, shutter speed to lens opening. Lens an updated Industar 61 L/D 55mm F2.8 Leica L39 39mm screw mount. Shutter would be 8 sec. to 1/2000."

"The FED-6 TTL, like the FED-670, is a prototype. It appears to be based on the FED-5, but with a CdS meter. Early prototypes are often non-working models and therefore not worth the high prices often asked. Like many former Soviet camera factories, FED are hoping for additional investment. If this were to be forthcoming, cameras like these may yet be put into production."

"After recieving Antonio Savini's letters (L43 and L 47), I wrote to the FED factory for information on the FED-6 TTL and Helios-113 and Kaleinar-5N lenses. I have received the following reply from Mr. Bodnia, their (FED) chief designer:

"Lenses Helios-113 1.8/4.0 and Kaleinar-5 2.8/100 were not in serial production. There was a trial batch with attachment M39*1 and with bayonet Leica M. Besides these two types there was a third one: Mir-61 2.8/28 (also with attachment thread and bayonet). These lenses were intended as changeable for FED-6TTL camera (prototype), which also was not in serial production or for retail sale."

Below is a somewhat revised version of a computer translated article, originally in Russian, and I believe from the forum on the KMZ site.

Fed-TTL: the photoresistor of system TTL

The camera Fed-TTL was a development of the Kharkov plant FED at the end of the1980s to the beginning 1990s. The CdS sensor was located on a moving rod behind the lens, which was removed at the moment of the exposure sequence.

This arrangement is more correct than other behind-the-lens metering systems proposed (ie. above the film gate, on the very bottom edge of the round image of the removed scene created by objective - let us recall, objective gives inverted image). However, the solution used in the FED is far from ideal. The light measurement is made in the upper part of the image, most frequently the more illuminated part of the scene, and so can require adjustment for averting underexposure. Furthermore, the small moving arm and meter can create the additional vibration of camera during the photographing.

Approximately so was solved the system of measurement after the objective in the project Kiev TTL of 1962, where were used two photoresistors, that are retracted from the image field during the exposure sequence. However, the best version of the potential realization of ekspozamera was used in special-purpose mikro-fotoapparatus of a series MA - using the reflected from the shutters, with the estimation of the illumination of scene and on the light at the moment of exhibition (system of the dynamic measurement Ttl- dm) reflected from the film.

I will add information if and when it becomes available!
