Depth Of Field - Leica SummArIt-S 1:2.5/70mm ASPH Notice D'utilisation

Central shutter
The LEICA SUMMARIT-S 70mm f/2.5 ASPH is available in two versions: with and without
a built-in central, or leaf shutter. You can use the master switch on the camera to specify
whether you want to use the camera's internal focal plane shutter or the central shutter on
corresponding lenses. The central shutter provides particularly short flash sync speeds (for
further details, refer to the relevant sections in the camera manual).
Focusing
In autofocus mode, the focus is set automatically by the camera and in manual mode by turn-
ing the distance setting ring (3; for further details, refer to the relevant sections in the camera
manual).

Depth of field

As Leica S lenses do not have an aperture ring, there is no depth of field scale. Refer to the
table on p. 74–75 for the corresponding values.
