Notes
The specified focal lengths of MOBOTIX lenses do not reflect the actual focal length
of the lenses, but the focal length (L
xx
mm) converted to 35 mm camera format.
For example, the MOBOTIX Super Wide-Angle lens has an actual focal length of
4 mm. This would be the equivalent of 22 mm on a 35 mm camera. This lens is
thus called
L22
.
Stated focal lengths of
MOBOTIX cameras are
given with reference
to a 35 mm camera
