I should add that FOV is really only a perfect comparison to use when comparing similar ratio rectangles (or other shape). It's not just a function of the lens but the image circle "crop".
With that in mind some adjustment would be needed to strictly compare a 4x5 (or similar ration 8x10) view camera lens FOV with a 24x36mm 35mm frame (which would need to be 24x30mm to be a straight-across comparison).
