I blame the PangalacticGargleblasters myself.

I had rather telescopically taken the aperture multiplied by the focal ratio to be the fl. As I said, real cameras and me are a very new thing! I'll google what those numbers actually mean.

To be fair though, I had done 600/8 = 75 and thought that was such an absurd number that it couldn't be true...
