90mm Summicron made in Canada. SEOOM. 11122. Manufactured in 1960. While most of the exterior is black chrome, black paint is applied to the rings near the depth of field markings. The red distance markings give it a cool impression. When detached from the lens head and combined with the 16462 helicoid, it can also be used as a lens for the Visoflex system. The appearance shows minor wear on the aperture ring, helicoid, and tripod mount. The black paint section has some paint loss on the ring edge, revealing a hint of brass. The glass in the middle element has two crystalline balsam separations. No noticeable effect on pictures. The helicoid and aperture operation feel smooth. Overall, in good condition.
