F number to solid angle
WebF-number of A2 = f D = f d2 = 1 p 2 2 = 2 p 2 = 2 p 2 p 2 2! = p 2 = 1.4 The F-number for A2, then, is 1.4. Note that even though the area A2 is half the area of A1, the diameter d2 is about 0.7 times as much as d1, so the F-number is affected similarly. As an exercise, try doing the same thing with A2 and a third circle with area A3 which is ...
