RF 70-200mm F2.8L IS USM

To us the most exciting lens to be revealed is the RF 70-200mm F2.8L IS. Part of our excitement is that a 70-200mm F2.8 is one of the workhorses of any system. Pros and enthusiasts use these lenses for a whole range of shooting situations, from portraiture to sports, so it's an essential ingredient for a system trying to appeal to high-end shooters.

Another piece of good news is that the lens uses Canon's Nano USM lens motors. The company is a little cagey about exactly how these work, other than that they provide linear, rather than the rotational motion of the ring-type USM motors used in DSLR lenses. What we do know is that the fastest and smoothest focusing lens in the RF system so far (the 24-105mm F4L IS) is powered by Nano USM, which bodes well for the 70-200mm.
