Rare antique C. P. Goerz Berlin Dopp-Anastigmat Syntor 180mm f/6.8 brass lens.

This beautiful German lens has been fitted with an M42 adapter ring for easier mounting and display.

Please note that no focusing mechanism is provided.

The aperture ring rotates freely, but the iris diaphragm is missing, therefore the aperture does not change.

Please note: This antique large format lens mounted in an M42 adapter ring may not reach infinity focus on standard DSLR cameras. Compatibility depends on your camera, adapter, bellows, or extension system.
