Overview

The Bausch & Lomb Tessar 90 mm f/4.5 Series 1c is a pre-WWII lens (likely late 1930s) originally for Graflex or view cameras. Optically, it delivers sharp images, especially at f/8 and f/11, with decent performance at f/5.6 (MFlenses). It lacks a shutter and has no focal length engraved, requiring adaptation (e.g., bellows) for use on modern cameras. Build is robust for its age. Suits photographers interested in vintage lenses for close-up or portrait work, accepting its limitations.
