M22M Camera Manual Part 1

2.7.6 CS Mount Version

The M22M-SecureCS is delivered with a CS mount
and a compact L24-L54 1/2" vario lens. To protect
the lens against the weather, this version comes
with a longer lens cover (43 mm inside, 53 mm
outside) with integrated glass pane and threads
for an external filter (40.5 mm x 0.5 mm). This
cover will work for lenses, which have a maximum
diameter of 36 mm and which are not longer than
43 mm.
Because of the image sensor's size of 1/2", you can only use CS and C mount
lenses (C mount lenses with adapter ring) for 1/2" sensors or larger. Using other
lenses will produce shadows at the image borders and will reduce image sharp-
ness. Vario lenses are not maintenance-free, they are definitely less robust and
less reliable in the long run as compared to the MOBOTIX M14 fixed lenses. This is
why the vario lenses are typically used in applications where locations are chang-
ing frequently, e.g. in industrial applications.

2.7.7 Lens Cover with Glass Pane

As an additional accessory, a heavy-duty lens
cover with a front glass pane is available for the
M22M models. This will improve the durability of
the lens cover when used in rough conditions (at
the sea, in sand storms, etc.). This lens cover also
has a thread size that fits external filters
(40.5 mm x 0.5 mm) available from photo shops.
For example, you could install a polarization filter
to cancel out the reflections from windowpanes
or windshields.
Using this lens cover together with the L22 Super Wide Angle lens is not recom-
mended, since this lens cover produces shadows at the image borders.
Make sure that the white ring remains in the lens cover, since the ring
reduces light reflections and prevents the camera LEDs from adding
reflections to the images.
