Looking at princelle's book, 'Cameras from the Soviet Union', one notices that the quality and ambition of FED material doesn't stop decreasing over thime. This is a fine example. The FED 50 is an involution of FED 35, a parctically identical model, only that it has a coupled rangefinder and a CdS cell meter instead of the hopelessly outdated selenium meter around the lens. Some like celenium bulbs, though. My wife is one of them; in fact the camera is hers.
The prior generation of this camera, the half frame Mikron, was indeed closely 'inspired' in the simpler models of Olympus PEN snapshot cameras, and also used a barrel selenium meter.
Hey, it is an automatic camera... with single program curve :) Wich means that it can only shoot in a very limited number of diaphragm/speed combinations, which I find fairly odd.
The previous models of this generation fo cameras, the 35 and the 35a, had a coupled rangefinder, a feature that the 50 lost. What the 50 kept was the dark green tinted finder, pretty useless in my opinion, as it doesn't need to offer any contrast with a rangefinder image.
This is how the glorious history of the camera makers from Kharkhov ends
A battered autumn leaf stops briefly on a rock, still for a short time while thousands of gallons of rushing water pass by. Soon it will depart this temporary home and continue its journey downstream.

The mixed toning didn't work so well... The warm tone paper just goes red all over very quickly. Selenium alone works well but doesn't give me the full red I wanted.

While I was on Tim Rudman's recent lith printing workshop, I was reminded how cemeteries can yield some striking images that suit lith printing very well. This prompted a return to an old 35mm negative, which I don't think has turned out too bad as a print.
