Quote:If the lens indeed is a 70-300mm f4-5.6 L IS USM III, it will not have an STM motor. My guess is that it will have revised optics, the old lens is not perfect, room for improvement. Filter thread size went from 58mm to 67 mm, by the way.in the picture they have a black lens without the red ring, so it's not an upgrade for the 70-300IS L but rather to the standard 70-300IS
