Angle Of View and Focal Length
Prepared 2005-11-11 by Bill Claff

### Introduction

In terms of lens specifications angle of view and focal length are measured strictly at infinity focus.
Angle of view at finite focus distances is meaningful but that is a separate topic and not covered here.

Angle of view is typically reported as a diagonal picture angle for a particular film/sensor size.
Sometimes the film/sensor size used is not stated or obvious.

Diagonal picture angle at a particular diagonal size is related to focal length by a simple trigonometric formula.

You can also rearrange this formula to obtain focal length from diagonal picture angle and diagonal size.

Some manufacturers, Nikon in particular; provide a more precise diagonal picture angle than focal length in their lens specification.
Stated focal lengths are typically rounded to the nearest mm; sometimes further.
So if diagonal picture angle is more precise then a more precise focal length can be computed using the focal length formula.

Nikon reports diagonal picture angle with a precision of 10 minutes or 1/6th degree.
By adding and subtracting ½ the precision from the reported diagonal picture angle we can compute a range of focal lengths; the “true” focal length falls in this range and the range implies focal length accuracy.

The following table lists picture angle and focal length data for a number of lenses.

The data in the green cells is entered specifications.
The data in the light green cells is the desired film/sensor size for picture angle calculations.
The data in the yellow cells is computed.

Zoom lenses are listed twice, once at each focal length.
Bold lens descriptions are auto focus, non‑bold descriptions are manual focus.

The computed horizontal pictures angle and vertical pictures angle are primarily of interest to photographers doing panoramic photography for the purpose of performing corrections before stitching images.
For example, I use 88.4 and 66.0 doing panoramic stitching of images taken with my 12-24mm f/4G ED AF-S DX Zoom‑Nikkor lens.

The computed focal length is generally within the accuracy of the published focal length; exceptions are listed in the column labeled as corrected.
A common example is the 50mm f/1.8D AF Nikkor; the computed focal length is 51mm rather than 50mm.

It appears from this table that only Nikon states picture angles that are independent from and not simply computed from the focal length.
