What's the relationship between digital camera's focal lenght and Blender camera units? (example: 5 mm in camera focal lenght in Blender is......?)
Thanks to all

the focal length has to do with the cameras viewing angle and has no spatial properties.

it's a different value, insteaqd of degree...
I don't remember the formula, but it's kinda the double tanh of the angle, or so....

yeah but the viewing angle is directly related to the focal length. and its a bit more complex than double the viewing angle.
it doesnt matter what the blender units are because it has no effect on 'blender space' whatsoever.
