This is probably the finest 500mm mirror lens available. Super sharp, fantastic contrast in a small package.
I've had this lens for ten years or so and used it probably a dozen or times.
Its almost perfect condition, and comes with many extras. The completely overpriced 82/86 adapter ring and Contax metal hood 5, 82mm protection lens in its original box and vinyl case. Also included is a Contax manual focus to Canon EOS. Also included is a Kaiser push-on lens cap that fits over the lens shade.
The original box, foam, instructions, pouch and everything as new. Super smooth focus, great lens to shoot with. If you are in Chicago and wanna inspect in person I work in the loop and you are more more then welcome to inspect in person.
Lens is $1500.00, shipping is $16.00 in the US only, payment via Paypal.
Thanks for looking!
