Focal Lengths of MOBOTIX Lenses
The focal lengths of MOBOTIX lenses are always relating to 35mm camera format.
For example, the MOBOTIX L20-L23 Super Wide-Angle lens has a true focal length
of 3.6mm. Converted to 35mm format, this translates to a 20mm lens on a 6MP
image sensor and a 23mm lens on a 5MP image sensor. You can use this focal
length to easily compare image formats and angles of view. In addition, you can
set this value on common 35mm or digital still cameras to the focal length (Lxx) of a
MOBOTIX lens to check if the resulting image suits the requirements for this camera.
