First time getting used equipment from KEH. I bought several vintage Nikkor lenses listed as "ugly" or "as it" to practice disassembly and re-assembly them, not expecting that they will even be usable. To my surprise, the optics of these lenses were better than listed, mostly just dirty or dusty, but no scratches or nicks. A couple only had cosmetic damages and were even immediately usable. Looking forward to making more purchases from KEH in the future.
