I have a 16mm Zenitar for my Nikon and I love it. Though Iíve heard of some problems with the quality control of some of the lenses, Iíve had no problems with mine. However, I would suggest buying from an eBay seller who sells a lot of Russian cameras and lenses and has good feedback. I think a lot of people try to pass off broken Russian cameras and lenses on eBay -- Though I see this more with the Kiev 88 cameras.
