LENS HOOD
The Leica Summilux-M 28mm f/1.4 ASPH comes complete with a screw-on lens
hood (1).
To attach it, screw on the square lens hood as far as it will go (clockwise). The
special design of the threads on the lens hood and the lens front mount (2b) –
with stop – ensures that the lens hood is correctly aligned. This guarantees that
the lens hood does not impair the optical path of the lens or the distance meter,
i.e. it prevents vignetting in the image and shadowing in the distance meter
measuring field. At the same time, the gap in the top left corner of the lens hood
minimizes coverage of the viewfinder image on the Leica M.
When the camera is being carried or used and is ready to shoot, this hood
should always remain fitted. It provides effective protection against contrast-
reducing stray light and also against damage and soiling of the front lens, e.g.
from accidental fingerprints.
Notes:
• The lens hood must always be screwed on as far as it will go.
• The front cover supplied is designed for use with the lens hood attached.
