I am selling a mint condition 200mm f/8 Nikkor M lens in a Copal 0 shutter with original caps and retaining ring for $500. The glass is perfect, and the shutter is snappy and sounds accurate. I simply don't need an ultralight lens because I don't do much backpacking, and I have another lens in this focal length that I use more. You can reach me at anthony dot karnezis at gmail. Thanks for looking.
