Lens Overview — C.P. Goerz 3" f/6

The C.P. Goerz 3" (76mm) f/6 Rectagon is a vintage large format prime lens manufactured prior to 1950, representing a piece of photographic history from one of the classic German optical houses. With a focal length of 76mm and a maximum aperture of f/6, this lens is designed for large format sheet film cameras, with compatibility spanning 4x5, 5x7, and 8x10 formats.

The lens features an in-lens shutter — a classic mechanical design consistent with large format lenses of its era — and operates entirely via manual focus, as expected from a pre-1950 optical instrument. There is no image stabilization, no autofocus, and no filter thread data on file, which are all typical characteristics of vintage barrel lenses in this category. The lens is classified under large format barrel lens compatibility, meaning it will require appropriate mounting solutions depending on your camera system.

For collectors, film photographers, and large format enthusiasts who appreciate the craftsmanship and optical rendering of pre-war German glass, the Rectagon offers an opportunity to work with a genuinely historical piece of photographic equipment.

Key Features — C.P. Goerz 3" f/6

76mm Large Format Prime: Provides a standard field of view on large format cameras, suitable for portraiture, architecture, and general work across multiple film sizes.

Pre-1950 German Optics: Manufactured by C.P. Goerz, a historically significant German optical house, representing early 20th-century lens craftsmanship.

f/6 Maximum Aperture: Moderate maximum aperture typical of large format lenses of this era, allowing for controlled depth of field on sheet film.

In-Lens Shutter: Self-contained mechanical shutter built into the lens allows for exposure control without a separate focal-plane shutter on the camera body.

4x5 and 5x7 Coverage: A 76mm lens at f/6 provides confirmed coverage of 4x5 sheet film; coverage of 5x7 and 8x10 should be verified against the specific barrel serial and design variant.

Manual Focus Operation: Fully manual focus design suits the deliberate, measured workflow characteristic of large format photography.

Description — C.P. Goerz 3" f/6

The C.P. Goerz 76mm (3") f/6 Rectagon is a prime large format lens with roots in pre-1950 optical manufacturing. Built for large format sheet film photography, it covers 4x5, 5x7, and 8x10 formats, making it a versatile choice across the large format spectrum.

The lens incorporates an in-lens shutter, providing a self-contained mechanical exposure system characteristic of classic large format glass. Operation is entirely manual focus, consistent with the deliberate, ground-glass-based workflow that large format photography demands. Image stabilization is absent, as expected from a lens of this era and type.

No filter thread size is recorded in the specifications, so photographers planning to use filters should verify compatibility independently. The lens falls under the large format barrel lens compatibility category, and specific camera board mount information is not listed — buyers should confirm mounting arrangements for their particular camera system. For those drawn to vintage glass and the craft of large format film photography, the Rectagon represents a tangible connection to early twentieth-century optical engineering.
