Leica Leica Lens Hood for the 35mm f/2 M & Aspherical Lens #12526 Thanks to minor modifications in the lens hood, a redesigned protective cover made of a soft plastic material can be used, which is also very comfortable to carry along. The lens hood can also be used with the foregoing model SUMMICRON-M f/2/35 mm (order number 11310 or 11311). It can be reordered as a replacement (order number 12 526) and comes with the protective cover.
