Angle of View Values
for Common Focal Lengths
Prepared 2006-11-22 (146/78858) by Bill Claff
The values for Angle of View
(AOV) come up frequently enough that I thought a list might be helpful.
Remember that focal length is stated for infinity and most lenses decrease in
focal length as you focus closer; so Your Mileage May Vary (YMMV).
Also, this is a table of rectilinear values; fisheye angle of view is a
different beast.
