How to use the table: Hopefully the table is quite self-explanatory, but let's say you are looking for the Field-of-view of a 50mm lens mounted on an FX body. In the column "Lens Focal Length", go down to the row marked "50mm" and then over to the green area marked "35mm & FX format (1)". The FOV for a 50mm lens would be 39.6 degrees horizontally and 27.0 degrees vertically. Diagonally, the FOV is 46.8 degrees.

Please note, this is a table of rectilinear values, i.e. values for rectilinear lenses; fisheye field of view is a different beast.

The values for Field of View (FOV), sometimes sloppily referred to as "lens view" or better, "angle of view", come up frequently enough at the forums that I thought a list might be helpful for quick reference.

For a 55mm lens on a APS-C/DX sensor format body, the field of view would thus be 24.0 degrees horizontally, 16.1 degrees vertically and 28.7 degrees diagonally.

Laser processing realizes a non-contact and highly precise processing method to cut materials at high speed using a lens to focus energy millions of times greater than the light found in the natural world. Laser processing machines that realized this technology play an active part in a wide variety of industries because of its high processing performance and overwhelming cost performance. The mission of laser optics manufacturers is to realize the maximum potential of the laser processing machine.
