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 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.
