Good gravy, these guys are brand new and a second lens is already in the works:

It's not clear if the 11mm is for FF or crop, but we will find out.
Comment #1: For all those who thought they had to buy a $3k11mm prime 11-24mm zoom from Canon! 
Comment #2: If that second lens is front filterable *and* it's for FF mounts, I don't want know what diameter filters it takes.
