Which brings us back to the reason Sigma images are "sharper"... due to the refusal to use AA-filters. If you remove the AA-filter from a Bayer CFA sensor, you will get the same kind of sharpness. Liked by some, disliked by those in the know (that is why most camera manufacturers put AA-filters in front).

I'm equally surprised by this claim - interpolated image always will be softer, AA filter or not. I guess the only situation where Bayer would be equally sharp is if someone created pure B/W sensor.
