I have owned and used several FSU cameras and lots of lenses.
And been more pleased than not.
Agat 18 to Kiev 60 and lots of 35mm cameras in between: Feds 2, 3, 4, and 5. Zorkis 1, 3, 4, and 10. Kievs 2,3, 4, and 4a. And a few others as well.
Mine have been always interesting, mostly usable, sometimes frustrating, and occasionally brilliant. Much like the other cameras I've owned.
And I still have a few more that I am wanting to try.
Yes, I started with the FSU gear because it was easier on my wallet but have since found that the gear has, for me, an appeal quite apart from that.
