COMPATIBLE LENSES

Sophisticated optical systems guarantee the excellent imaging
performance of the SL lenses. In the design phase for the optics, a
homogeneous performance across all focal lengths, aperture and
focus settings is a high priority. That is how SL lenses can be used
for optimally creative results in any situation.
Leica M and R lenses can also be used in conjunction with Leica
M/R L adapters.
L-MOUNT LENSES
In addition to Leica SL lenses, the Leica SL3 can also accommodate
Leica TL lenses with full functionality via the L bayonet. The camera
will automatically switch to the APS-C format when a TL lens is
attached. A variety of compatible lenses from manufacturers of the
L-Mount Alliance are also available.

EXPOSURE METERING AND EXPOSURE CONTROL USING VARIO
LENSES
Some Leica TL, SL Vario, and L-mount lenses have a variable light
intensity, which means that the effective lens aperture varies de-
pends on the configured focal length. Make sure to set the desired
focal length before storing the meter value or changing the shutter
speed/aperture combination to prevent incorrect exposure. Please
read the sections on "Exposure" starting on page 146 for more
information. Make sure that the aperture setting on the flash unit
matches the camera aperture if you are using a non-system com-
patible flash unit.
