Numbers Lloyd..not physical diameter.
f 1.2 is a lower NUMBER than f32. Bigger hole....smaller number.

gunner, gunner, gunner... I know what the numbers mean. I not only did
the full-monte photography thing from the time I was 15 until 22, but I
also have built and use telescopes. Focal-length/aperture ratio (f-stop)
is one of those, um... 'entry level' things.
