This is a used Magnon Auto Tele (made in Japan) 200mm fixed focal-length telephoto lens, serial #755396, that was designed for Olympus manual-focus cameras.
The f-stop range goes from 3.3 to 22, there is a built-in sliding lens shade, the cosmetic condition is 'excellent', and front & rear caps are included.
The glass is clean on both ends, however, THE BLADES WORK SLOWLY. There is a TINY amount of oil visible on the rear of the blades, but there is none visible on the front of the blades.
This lens is offered for $35.00, shipped to the CONUS. Payment methods include Paypal, money orders, and personal checks.
Thanks for looking!
