Zeiss's large format Tessar — the classic 150mm f/4.5 for medium and large format photography.
The Zeiss Tessar 150mm f/4.5 in large format configuration applies the classic Zeiss Tessar four-element formula to view camera use, providing a normal focal length for 4x5-inch photography. The Tessar design, patented by Zeiss in 1902, is among the most successful optical formulas in photographic history.
The lens provides 150mm at f/4.5 maximum aperture with the Tessar four-element three-group formula, typically in a Compur or Copal shutter, Carl Zeiss optical quality, and coverage suited to 4x5-inch with moderate movement capability.
Large format Zeiss Tessar lenses are collected for their German optical heritage and historical significance. The Tessar formula provides excellent sharpness when stopped down, making it well-suited to large format landscape and architectural photography where f/16 or smaller apertures are commonly used.
Test shutter operation. Inspect element condition for clarity and coating integrity. Verify image circle coverage on the ground glass at working apertures. Check shutter blade condition and timing.
