If you specify a camera angle, it directly specifies the horizontal 
field of view; the aspect ratio (relative length of the right and up 
vectors, which should ideally fit the image aspect ratio) determines the 
vertical field of view.

Try the ultra_wide_angle camera; I consider it far superior to the 
pinpoint projection of the standard perspective camera.

One hint for focal blurring: Try to figure out what size an eye's pupil 
would be in scene dimenstions, and set the aperture value to something 
in that order of magnitude.
