Field of View Values for Common Focal Lengths
Prepared 2006-11-22 (146/78858) by Bill Claff

 

The values for Field of View (FOV) 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 field of view is a different beast.
