Lens Angle

[Akimbo]

Does anyone know of a good book or web site that has a table or formula for lens angles versus sensor size? A comparison to film lens angles would also be fine.

Thanks

Here is a link to an interactive site that will show you the FOV for film/full frame lenses and for cropped sensor 1.5/1.6 sensors.
Lens Focal Length and Field of View

For tinier sensors, most companies quote 35 mm equivalent Focal lengths and can be extrapolated.

If you pan down this page you can find a calculator I sorta like:

Field of View - Rectilinear and Fisheye Lenses

Comparison of popular sensor sizes:

The popular Canon A570 is 1/2.5

The Canon G and S series are 1/1.7

The Oly XZ1 is 1/1.6

The lens angle is related to sensor size and focal length.

Construct an isoceles triangle, with the base the diagonal dimension of your sensor, and the height of the triangle the focal length of the lens. The angle of the vertex of that triangle is your angle of view (at least for a non-fisheye lens).

Basically, imagine a pinhole camera with the pinhole moved out from the sensor by the focal length of your lens, say 105mm. Then it's simple geometry to figure out the angle of view of eth sensor through the pinhole.
