dust into the interior of the camera.
A lens acts as a burning glass if it is pointed
directly at the sun. Protect the interior of
your camera by covering the lens with the
lens cap, or keeping the camera in a case
or in the shade. Each lens, in addition to its
type, has its own Serial No. engraved on
the front lens mount. Make a note of this as
well as of the Serial No. of the camera,
which you will find on the back of the
baseplate of your LEICAFLEX. This may be
of great importance in case of loss or theft.
A brownish-violet sheen indicates the high-
quality coating of the LEICAFLEX lenses.
These reflection-reducing layers vastly in-
crease the brightness and brilliance of the
picture.
Remove dust from the external surfaces of
your lenses with a soft sable brush or with a
clean, dry, soft piece of linen. Special cloths
used for the cleaning of spectacles are not
recommended; they are chemically
impregnated and may therefore attack the
glass of the lenses (glass used for
spectacles differs in its composition from
the optical glasses of high-quality camera
lenses).
In unfavourable conditions, for instance on
the beach, at sea, in subtropical climate etc.
a colourless U.V. absorbing filter will
protect the front element of the lens from
external damage by seawater spray and
sand. Such an additional colourless and
optically flat glass plate, i.e. a filter, may,
however, cause undesirable reflections at
certain angles of light incidence, especially
in centre jour and artificial light. The lens
hood, too, protects the lens against acci-
dental fingermarks and raindrops.
