Hi, I am selling a Carl Zeiss Biogon 28mm f:2.8 T* (serial number 15544448), M-mount in absolute mint condition. Bought in Dec 2014 from Rajala. I did not use it much at all, it's been in the box most of the time and has been always used with a protective filter. I would like 800 euros for it. Location: Helsinki but can ship. Thanks, Jerome
