Camera lenses

AVT offers different lenses from a variety of manufacturers. The following

table lists selected image formats in width x height depending on camera

type, distance and the focal length of the lens.

Note



All calculations apply to the principle planes of the lenses:

these are unknown (real lenses are not infinite thin).

All calculations are valid only for a distortion free optical

image (among other things: not valid for fisheye lenses).
