Hello,
I see that many users of cameras from the former USSR, like or prefer the FED-2.
Its quality is in the simple mechanic, the large rangefinder's base (from the Contax/Kiev one). The design is also pleasant, I admit.
In other words, the say "what there isn't, it won't break" is right for the FED-2; plus, the lenses of the Jupiter series, that are all fine to very fine.
Personally, I prefer the Kiev, for its very fine shutter and the precision. I have my first Kiev (a 4A made in 1968) since 1975 and this used to me to the Contax-Kiev system.
A Kiev RF camera, in my opinion, is well worth to be repaired and maintained, even if the price could be higher than the price paid for the camera itself. Once back in its pristine condition, a Kiev can be a camera of professional level, lasting for many years of reliable service.
