Camera - how many degrees for field of vision

Hi, I'm still quite green with this language and am working on my first game still.

I was wondering, does anyone knew how many degrees outward a camera draws?

I've been looking into human periphial vision, which seems to be about 90 degrees left/right and 50 degrees up/down. I was hoping to have a few other player races, like lets say an alien race, that might have a slightly different ratio for there field of vision.

Is there anyway of changing how many degrees the camera is using to render a scene?

Anyway, those are my 2 questions, thanks in advance :)

There is a CameraFOV example in the archives:

That's interesting :) Is the CameraZoom command our only tool for adjusting the angle then? I'll play around with this and see if it gives me the look and feel I'm interested in.

Thanks!
