Focal lengths of MOBOTIX lenses are always given as compared to a 35 mm camera.
For example, the MOBOTIX Super Wide-Angle lens L20-L23 has a nominal focal
length of 3.6 mm. Converted to 35 mm camera, this would be a lens with 20 mm
or 23 mm focal length, depending on whether it is combined with a 6MP or a 5MP
image sensor. Converting the focal lengths to 35 mm camera as a known format
provides for better comparing the image formats and the angles of view of the dif-
ferent lenses. Another benefit is that you can easily set a 35 mm camera (analog or
digital) to the same focal length (Lxx) of the MOBOTIX lens to obtain the same angle
of view. This approach greatly facilitates lens selection.
