DESIGN OF THE LEICA SL LENSES
EN
In principle, all Leica SL lenses have the same external design: on the front mount there is
an
2
external bayonet fitting
for the lens hood
and an internal thread
for filters, a setting ring for
2a
1
2c
the distance
and a red index button for orientation when changing lenses
. Furthermore, the Leica
3
6
Vario-Elmarit-SL 1:2.8-4/24-90mm ASPH. has an additional ring
4
for setting the focal length and the
appropriate index
.

In the bayonet flange there is a contact strip
by means of which the entire data exchange between
7
the camera and lens is effected, including the control commands for autofocus, stabilization and the
aperture.
FOCUSING AND SETTING THE FOCAL LENGTH
The camera focuses automatically in autofocus mode; in manual mode turn the distance setting ring
on the front to focus
. The speed at which you turn the ring determines how quickly the setting
3
changes. In this way, you can make fine adjustments just as quickly and precisely as you can move
from the close-up to long-distance range. Please refer to the relevant sections in the camera
instruction for more details. The focal length - and thus the desired shot composition – is set with the
rear ring
4
.
DEPTH OF FIELD
Since Leica SL lenses do not have an aperture ring, there is no depth of field scale. Instead, the
relevant front and rear limits of the depth of field can be read in the camera's cover display together
with the distance set.
