A 4mm lens with an 8mm aperture gives what FOV?
Please answer in degrees and PPF at 30 ft (assuming 1080 res on a 1/2" digital imager)
Crap! I wouldn't have a clue!
It is pretty much teaching basics and shooting manually. I am in no way a professional. When i take pictures I pretty much use the metering system of the camera to determine the correct exposure, then adjust the aperture and shutter speed to get the desired effect I am trying for.
I have a Nikon D750. Do you take pictures? What kind of camera do you have?

BS question. Apertures are measured in f-stops, not mm's. And it wouldn't produce a FOV, it would be DOF.
