35 mm-equivalent focal length to diagonal angle of view
Type a value in mm eq. to get it in ° diagonal instantly.
63.44° diagonal
That's 1.35× as long as a phone’s main camera, while a normal lens is 1.43× longer.
What it means
How wide does it see?
Angles are for a rectilinear lens focused at infinity on a 3:2 frame. Fisheye lenses and close focusing change them.
The math
How to convert mm eq. to ° diagonal
Angle of view is 2 × arctan(d ÷ 2f), with d the frame’s width, height or diagonal (36, 24 or 43.3 mm for full frame) and f the 35 mm-equivalent focal length.
Example: 35 mm eq. = 63.44 ° diagonal.
