While I'm no expert, perhaps the equivalence theory only really applies to the depth of field being the same, and not the amount of blur you see.

I'm pretty sure equivalence theory says that two equivalent lenses at the same aperture and shutter speed (with ISO adjusted for sensor size) would take "the same photo".
