DISPOSAL OF ELECTRICAL AND ELECTRONIC EQUIPMENT
(Applies within the EU and for other European countries with active waste separation policies)
This device contains electric and/or electronic components which must not be disposed of in general
household waste. Instead, it should be disposed of at a recycling collection point provided by your
local authority. This service is free of charge. Any standard or rechargeable batteries used in this
device must be removed and disposed of separately in accordance with local regulations.
Please contact your local authorities, waste disposal collection point or the retailer, from whom you
purchased the device for more information on correct waste disposal.
SAFETY REMARK
• A camera lens can have the effect of a magnifying glass when exposed to direct frontal sunlight.
The camera must therefore be protected against extended exposure to direct sunlight. Using the
lens cap and keeping the camera in the shade (ideally in its camera case) will help prevent damage
to the interior of the camera.
GENERAL NOTES
• Make a note of the serial numbers of your camera (engraved in the base of the camera housing)
and lenses, as this information will be extremely important in case of loss.
• Make sure to always have a lens or the camera bayonet cover attached to prevent dust or other
foreign bodies penetrating the camera.
• That is why you should always replace lenses quickly and in a dust-free environment.
• Never store the camera bayonet cover or the lens back cover in a pants pocket, as they will attract
lint and dust, which could then be accidentally introduced into the camera.
• Leica releases firmware updates for lenses at irregular intervals. You can download any new
firmware version from our homepage and transfer it to your lens.

DESIGN OF THE LEICA SL LENSES
All Leica SL lenses basically look the same on the outside: On the front mount there is an external
bayonet fitting for the lens hood and an internal thread for filters, as well as a focus ring and an
alignment button for lens changes.
All data exchange between the camera and lens is effected via a contact strip in the bayonet,
including the control commands for autofocus and aperture.

FOCUSING
In autofocus mode, the camera sets the sharpness automatically, while the user turns the focus ring 3
manually in manual mode. The speed at which you turn the ring determines how quickly the setting
changes. You can therefore make fine adjustments or quickly move from a close-up to a long range
setting. Please refer to the relevant sections in the camera manual for more details.
DEPTH OF FIELD
No depth of field scale is provided, because Leica SL lenses don’t come with an aperture settings
ring. Instead, the top display of the camera shows the near and far focal length limits of the depth of
field alongside the set distance.
LENS HOOD
APO-Summicron-SL 50 f/2 ASPH. comes with a lens hood 1optimally adapted to the beam paths.
The perfectly symmetrical bayonet fitting allows an attachment of the lens hood in reverse for more
compact storage. In both cases, it is attached (with the lens cap removed) with one of the alignment
points on the lens hood 1a aligning with the alignment point on the front mount of the lens 2b. It is
then turned by approx. 30° in clockwise direction until it audibly clicks into place.
The lens hood should remain attached as long as the camera is carried ready for use or is in use. It
effectively eliminates contrast-reducing stray light and protects the front lens against damage and
soiling (e.g. accidental fingerprint marks).
FILTERS
APO-Summicron-SL 50 f/2 ASPH. is compatible with screw filters of type E67. Matching filters are
available from Leica.
REPLACEMENT PARTS/ACCESSORIES

MTF DIAGRAMS
Infinity (∞)Close distance (0.5 m)
MTF GRAPHS The MTF is shown in each case f or the maximum aperture and the aperture values 5.6 and 8.0 for long focusing distances (infinity).
The contrast is plotted for 5, 10, 20, 40 lines/mm for the height of the format for tangential (dashed line) and sagittal structures
(continuous line) for white light. The plots for 5 and 10 lines/mm provide an impression of the contrast performance for coarser object
structures and the 20 and 40 lines/mm plots document the resolving power for fine and finest object structures.
