Notes
The name of the MOBOTIX lenses reflects the actual focal length of the lenses as well
as the focal length converted to 35 mm camera format. For example, the MOBOTIX
B041 Super Wide-Angle lens has a nominal focal length of 4,1 mm. Converted to
35 mm camera, this would be a lens with 22 mm focal length.
Converting the focal lengths to 35 mm camera as a known format provides for better
comparing the image formats and the angles of view of the different lenses. Another
benefit is that you can easily set a 35 mm camera (analog or digital) to the same
focal length of the MOBOTIX lens to obtain the same angle of view. This approach
greatly facilitates lens selection.
