The person shooting the Oly macro wasn't expecting much, he's a professional photographer who's done extensive macro work over the last 20+ years, and was impressed by the Rokkor's performance.

Generally....there's more than one way to bake a cake and there's many many ways to do Macro photography. One of my best macros was a close in of a backlit Dahlia shot on a very grainy Focal 400 slide film and using a 300 mm Sigma that wide open tended toward soft focus. It was in most respects the wrong lens and the wrong film but the combo gave a great result.
