Lens Field of View Chart (for 1/3" CCD Video Cameras) |
|
|
*Beware
of many online lens calculators which produce inaccurate angle measures
for these focal lengths. Also, most 1/4" CCD cameras produce
a significantly narrower field of view with the same focal length
lens.
**Due to the
physical nature of lens optics, the numbers listed below should
be considered accurate to within ± 3° and therefore a
few feet / meters as well. They are intended as approximate guidelines
to help select the appropriate lens, while each camera in fact has
its own unique field of view with each specific lens. In addition,
C- and CS-mount lenses typically deliver a slightly narrower field
of view than our comparable board lenses.
***Lenses wider
than roughly 5mm produce "artificially" wider fields of
view than more telephoto lenses. In order to do so, the video image
is slightly curved at the edges of the screen. While this artificial
distortion is nominal for focal lengths between 4.3 and 3.6mm, curvature
increases with wider angle lenses. |
