This is a classic Leitz Canada Summilux 35mm f1.4, a tiny pre-aspherical wide angle lens for Leica M mount cameras. Cosmetic condition is excellent, with minor paint wear; focusing is smooth, diaphragm is clean. The glass has a touch of light dust, but no haze or fungus- it's nice and clean. A beautiful little lens. Includes a Leica 12504 hood, which has a very light deformation in the front rim and a touch of paint wear.
