Notes
The specified focal lengths of the 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 L25 Super Wide-Angle lens has an actual focal length of
4 mm. This would be the equivalent of 25 mm on a 35 mm camera. It is therefore
referred to as an L25. 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.
