Overview

The Bausch-Lomb Tessar Series 1c 90mm f/4.5 is a vintage lens praised for its speed and generous coverage, particularly for large format work. Studioq.com notes its beautiful rendering on collodion dry plates and excellent detail. On forum.mflenses.com, users report sharp images even wide open, with good performance at f/8 and f/5.6 (Nesster). Build quality is typical of early 20th-century lenses, often mounted on Graflex or view cameras. It suits photographers seeking a classic Tessar look for landscapes or portraits on 4x5 or whole plate formats, though it lacks a built-in shutter.
