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
different sizes, converting the focal lengths to 35 mm camera as a known format
allows the image formats and the fields of vision of the different 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.
