Hmm, the focal lengths have little to do with equivalent apertures.

Equivalent images have the same field of view by definition. From this follows that equivalent apertures are directly linked to focal lengths used. 28/24=1.17 corresponds to abot 1/3 stop. That's why I shot the repeat test at f/7.1 for 60D and f/8 for D800. The resampling complicates the equivalence calculations, of course.
