dojoklo: Your example video showing "the differences between the FlexiZone single-point phase-detect AF and Face-detect/Tracking autofocus" is a little weird at best, and misleading at worst. First, one really wouldn't consider Face Detect to be the "default" AF mode - it is simply one of the 4 modes that the user can choose from, and it just happens to be the first one listed. The user is expected to select the mode that best fits the scene, and so that being said...

Why do you keep trying to use Face Detect to focus on a scene clearly without a face, and then commenting how there is a lag? Yes, there is a lag as the camera ponders why the user left it set on the Face Detect mode when there are no faces to be found! And then the camera switches automatically to FlexiZone-Multi as designed. The lag can be easily avoided by setting the camera in the appropriate AF Mode before shooting, and thus could basically be considered user error.

Good point chj. And I didn't really think of it as "anti-Canon," but rather more as anti-common sense or anti-RTM!

It just came across to me as very curious, and not much different than if they had said "In the default Evaluative Metering mode, the camera does a poor job spot metering. However, if you set it on Spot Metering, the spot metering performance improves dramatically."

So, kind of accidentally disingenuous I suppose. I just think a clearer walk-thru and trial of the AF Modes, with how they are designed to work, would have been more informative and useful: Face-Detect (used with a face), then FlexiZone-Single (used to "spot" focus), then FlexiZone-Multi (used to let the camera pick the focus). (And Quick Mode to make use of the Viewfinder AF sensor but not the new Dual Pixel CMOS system.)

There are a couple very important aspects of the 70D that this preview does not address. If you could please add some info it would be helpful:

1. Which Menu settings and Custom Functions does the 70D have/ lack compared to the 7D and 6D? These differences of functionality and customization are what can make/ break the decision for a semi-pro user or someone considering it as a second body.

2. Which AF Area Selection Modes does the 70D have? While the 19 pt AF system is similar to the 7D, The fact that the 70D appears to only offer Single Point, Zone, and Auto 19-point (while eliminating Expansion and Spot) could make or break the decision for a sports, action, or wildlife shooter (the Canon Europe specs and video seem to confirm only 3 AF Area modes.)

Thanks

If you are interested in this type of layered composition and "story-telling" be sure to have a look at artists like James Rosenquist and Robert Rauschenberg, who created painted works with a related approach, with great insight and subtlety.
