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 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.
