i'm not sure if this exist yet, but here is another million dollar idea for someone.
a digital camera with an adjustable field of view that can be set by degree from the camera.
there are already lots of fov calculators out there..
for example:

(variety of different calculators)
then this security company has a fov calculator for use with their equipment:

as far as having the calculator built in to the camera itself, i'm not entirely sure how useful it would be from a user point of view.. trying to set up a shot based on degrees isn't any more helpful or understandable than lens length (imo)
