One of my own favourite colour pictures was taken with a Fed-4 and Industar 61L/D. A mundane subject but the colours really popped in a way that was sharp and saturated without being over-saturated. They can be good lenses on the right body. I got rid of mine after testing it on a Leica III, several years before I discovered that a lot of FSU LTM lenses focus a bit off on non-FSU bodies. I've regretted it since.
