The push-on style Lens Cap from Leica is compatible with the Summicron-M 35mm f/2 lens.
The silver anodized cap is designed to protect the front element of the lens when it's not in use. The cap can be kept as a spare, or used as a replacement item for the one originally included with the lens.
Leica Camera AG (‘LEICA’) provides a two-year product warranty for your LEICA product, including the accessories contained in the original packaging, valid from the date of purchase from an authorized LEICA dealer.
