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 L11 hemispheric lens has an actual focal length of 1.8 mm.
This would be the equivalent of 11 mm on a 35 mm camera. This lens is thus called
L11
. 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.
