Focal lengths of MOBO-
TIX lenses are always gi-
ven as compared to a
35mm camera
To determine the lens you
need, simply use a camera
with zoom lens to find a
matching MOBOTIX lens

Note
The focal lengths of MOBOTIX lenses do not reflect the actual focal
length of the lenses, but the focal length (
Lxx 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 .
Converting the focal lengths to 35mm camera as a known format pro-
vides for better comparing the image formats and the fields of vision of
the different lenses. Another benefit is that you can easily set a 35mm
camera (analog or digital) to the same focal length as the MOBOTIX
lens (Lxx) to obtain the same field of vision. This approach greatly facili-
tates lens selection.
