Third-generation Summicron 50mm f2. The name was updated to Summicron-M, adopting the same naming used today. Leica product code 11819. Serial number in the 3.10 million range, manufactured in 1981. Made by Leitz Canada. Designed by Walter Mandler. The optical construction was changed from the 5 groups 6 elements of the 2nd version to a 4 groups 6 elements design.

This lens is an early example of the 3rd Summicron, featuring the distinctive protruding focusing tab. Overseas, it is sometimes nicknamed Tiger Claw.
The actual weight is 191g. Despite its f2 large aperture, it remains light and compact. The minimum focusing distance is 0.7m, allowing for relatively close shooting.

While it lacks a sense of luxury in its exterior finish, improvements in color balance and contrast make it a very practical and easy-to-use lens.

Minor rub marks can be seen on the front edge of the barrel and around the corners, but overall the exterior remains clean. There are no noticeable scratches or dents. A nicely balanced, clean condition that is just right for those who want to actively enjoy shooting.

Fully overhauled in February 2026. The aperture and helicoid now offer a smooth operation with a well-judged, moderate torque. Rangefinder coupling shows a very slight tendency toward back focus at close distances up to around 2 meters, but it is well within a practical and usable range.

The glass is clear and bright, with no haze. Only very slight coating wear can be detected when viewed under strong LED light, and it has no effect on actual photography. Test shots taken with our in-store demo body also produced excellent results.

The matching-number original box, 12538 hood, and 14033 hood cap are included.

Also recommended for a collection.
