Notes
The specified 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. It is
therefore referred to as an L22. Since the image sensors in digital cameras have
dierent sizes, converting the focal lengths to 35mm camera as a known format
allows the image formats and the fields of vision of the dierent lenses to be
calculated and compared more easily. 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 facilitates
lens selection.
