Dave Etchells/Imaging Resource: I guess we might as well start out with the 6D. Obviously, that's the big news. There's been some discussion online about the 6D having a smaller number of AF points than previous Canon DSLRs and, in particular, the single cross-type sensor in the middle. Is there a downside to offering more cross-type points or is it a cost issue? Is it a matter of product differentiation among your line?
Mike Owen/Canon: It's a variety of reasons, really. I mean, yes, there is the cost side of things, but what we've tried to do with the autofocus system on the 6D is to actually improve low-light performance. It goes down to EV -3. So when emphasizing low-light performance, we've always had to make elements of the AF system larger, which limits our ability to put in more cross-type points.
