Sigma's new lens designations will fit into one of the following three catagories: Art, Contemporary, Sports. They will no longer use the EX designation for superior glass.

This sounds idiotic. It seems like they're trying to dumb down the designations...I prefer clear designations that, yes, require one to memorize a few things, but ones where you look at the numbers and letters on a lens and you know exactly what you have in your hand (FL, speed, type of focus motor used, whether it's FF compatible or not, if it's top of the line or not, etc)...this sounds whole "Art" thing (while the lens itself may be a top performer and certainly a beautiful design) is just plain silly.
