I have these 2 Carl Zeiss manual focus lenses in M42 screw mount. I bought them recently (around 6 months ago) brand new from a German supplier, and they have seen very little use.
They are in mint condition. No signs of use whatsoever. Original boxes and papers are still available. Each is fitted with a B+W UV MRC F-PRO filter since they were received (included in the sale), and they are stored in a dry cabinet at all times.
Prices include Paypal and shipping by EMS (wherever available).
ZS 50: 535$ ZS 35: 760$
Thank you very much for looking.
