I decided to sell a real gem I bought a while ago - an extremely rare Vivitar Telephoto 135mm f/1.5 Professional.
The lens was produced in a very small batch of 30 pieces (some claim 300, but it's actually unknown, how many were made) in 1967, with a preset T-mount. I bought mine in Nikon F mount (yes, it does focus to infinity), but it can also be used with practically all other mounts (Canon EF and EF-S, Sony/Minolta, Pentax, 4/3 and M4/3 ...).
What's also interesting, is that mine carries a serial number of 19671001, which probably means it's the very first of it's kind.
Lens info:
Picture angle: 18°
Number of diaphragm blades: 16
Minimum f/stop: 22
Closest focusing distance: 1.65m
Weight: 1.970g (2.170g with lens hood, tripod collar and rear bayonet cap)
Dimensions: 100 X 155mm
Lens hood: metal screw-in type, generic
Tripod collar: yes
Front filter diameter: 95mm
When I bought it, it was in a pretty bad shape; lot's of scratches, fungus and dust inside, so I decided to get it refurbished. Two technicians at Fotomehanika camera services in Slovenia took it apart in March this year, cleaned it, polished a few lens element inside and voila - I was given back a really nicely done piece of glass.
The reason for selling are some changes I just done in my photography business and the need to purchase 17mm and 24mm Canon's TS-E lenses (also interested in a trade but only within EU - the Vivitar is for sale worldwide).
