This is a used Sakar f-8 500mm mirror lens, serial #970538. This lens, like most other mirror lenses, uses the t-mount system of mounting. There is either a Canon manual-focus compatible or Nikon t-mount that is available and included with this lens.
Of course, it will work with any other t-mount that a person might have or obtain.
The overall condition of this lens is 'excellent', however, it has an extremely small mark on the front element, which would not affect a thing 95% of the time. You'd have to catch the light (usually the sun) JUST RIGHT, and then maybe you'd get a small 'flare'.
This fine lens is sold complete with the original factory leather case and your choice of the above-mentioned t-mounts.
We've added the following to sweeten the deal! We'll include a t-mount 35mm Soligor lens that looks like new!
You get the mirror lens as above plus the 35mm lens booted!
The price is $75.00 (or make offer! trade?), shipped to the CONUS, and payment methods include Paypal, money orders, or personal checks.
Thanks for looking!
