It says f0.6on the flight case the lens came with which I assume is accurate as it's seems to be the original factory case. Any idea how the intensity is calculated?

All I know is that the speed is the distance from the lens to the focal plane divided by the lens diameter. With a compound lens, I'm not sure which lens element.
