Lens hoods
The individual Leica M lenses are supplied with
various functionally designed lens hoods. On sev-
eral lenses, they are built in, and have a teles-
copic design. Lens hoods should always be used
because they provide the lens with effective
protection against stray light and irradiation and
also against rain and fingerprints.
