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).
