Interesting, the halo is much wider than what would likely be produced solely as an aliasing artifact on the high contrast boarder. It looks like it may be a combination of adjacent pixel spill (due to the high contrast transition) and the lens aberrations. I would have thought that the FA100/2.8 macro would have been pretty well corrected for chromatic aberrations? I'd be keen to try my Voigtländer Macro APO-Lanthar 125mm F2.5 SL, I might get a chance when I meet with Christian next week.
