The Zeiss 46mm Front Lens Cap is a replacement cap for Zeiss ZM rangefinder lenses that feature a 46mm filter thread. Keeping the lens covered when not in use will protect it from dust and scratches. The lens cap is a snap-on type that prominently features the Zeiss logo.
The centered release mechanism makes it possible to remove the cap while there's a lens hood attached.
