Overview

The Canon TV 2000mm f/11 is a discontinued catadioptric supertelephoto lens (1960-1975) designed for Canon SLRs and TV cameras. It offers extreme reach with a 40x magnification ratio relative to 50mm. Optical strengths include a high magnification for distant subjects, but the fixed f/11 aperture and lack of stabilization limit low-light use. Build is heavy at ~11 kg and manual focus only. It suits specialized applications like sports, news, or wildlife where extreme telephoto reach is paramount, but handling is cumbersome.
