Use a fi Iter (optional)
Before putting a filter on the lens, make
sure it is compatible.
~ Refer to "Specifications" for
l.t:J compatible filter size (p. 21).
P.\ • Afilter is a precise optical product.
~ Keep away from dust, dirt or
scratches. Also, do not try to mount
two or more filters at the same time.
Doing so may deteriorate the image
quality and cause vignetting.
•
In case of a thick framed filter, the
vignetting
can occur with a wide-
angle lens.
What is vignetting?
Vignetting refers to when the edges
or outer parts of an image get dark or
are hidden in black due to the reduced
intensity oflight in surroundings of
the screen. It can a_ lso occur when
accessories such as converters or
filters
are mounted, as the viewing
angle of the lens is hidden.
17
•

Use a lens hood (optional)
To prevent deterioration ofimage quality due to internal reflection oflight, use a lens
hood. A lens
hood is an optional item that is available only for the Samsung 20 mm F2.8
lens.
Install the lens hood as shown in the picture below.
~ 'Mlen installing the lens hood, be careful not to rotate the focus ring •.

Cautions when using a flash with the lens
When
you
use
a
flash
in
situations where the distance
from
a subject
and
the
camera
is
close,
the
flash
light
is
partially
blocked
by
the
lens,
causing
some
parts of
the
photo
appear
dark.
Check the distance
between
the
camera
and
subjects
when
taking
photos.
Distance interrupted
by
the
flash
light
may
vary depending
on
the
type of
lens.
I'U'it
Light
from
the
flash
may
be
blocked
by
the
hood.
Remove
the
lens
hood
when
using
the
~
flash
.
