The User's Review: Two 500mm F8 Mirror Lenses,Branded By Kalimar and Vivitar

Both are made in Korea (South Korea, officially the Republic of Korea) , are of MC/multi-coated, have 72 mm-front-filter and 30.5 mm-rear-filter threads, and are mounted on a T-mount adapter that is available for various camera mounts.

The obvious differences between the two are: the surface textures of rubber coats on focus rings, and marks on the lens bodies.

I believe, that they are produced by the same manufacture and their parts are exchangeable.
