Samsung Galaxy S4 Camera Area Of View?

Does anyone know what the area of view is on the Galaxy S4 smartphone camera. The specs say it is a 13MP camera but has no info on the lens.


This site says 69Ā°:

"Additionally, the GS4 rear camera lens uses an f/2.2 aperture, 4.235mm focal length and a 69-degree angular field of view; the 1/3.06-inch sensor offers a pixel size of 1.12 microns (compared to 2.0 microns on the One). Its 13MP resolution is set at an aspect ratio of 4:3, so 16:9 fans will need to go down to 9.6 megapixels for a widescreen option."
