The E49 Lens Cap for Select Leica Lenses from Leica is a replacement or spare snap-on lens cap for the 135mm f/3.4 M lens and the 75mm f/2 M lens. Lens caps protect lenses from scratches, fingerprints and the elements while not in use. With such fine lenses as the Leica 135mm and 75mm f/2, a replacement lens in your camera bag is a good idea in case you lose the original while out shooting. The Leica script name logo is on the front of this lens cap.
