The chart on the left designates which pairs of lines are used for which focus points. Please note that several of the lines are used by more than one point, thus the coverage area of adjacent points can overlap. All points have a much larger coverage area than the squares in the viewfinder indicate. Most are not centered. | |
| Jun 26, 2013 at 10:46 | comment | added | Michael C | I'm lukewarm on the "advantages" of the 7D focus system. It does have more points and configurable ways to use them. With AFMA it has the potential, after proper calibration, to be more accurate than the Rebels and 60D (that lack AFMA), but it is no more consistent than they are. See lensrentals.com/blog/2012/08/… Understanding the coverage areas make it more usable for those who are willing to learn actual coverage for each point, as opposed to the location of the squares. blogs.stonesteps.ca/showpost.aspx?pid=54 | |

| Jun 26, 2013 at 10:05 | comment | added | Berzemus | I'm tempted to add the 7D has a 100% viewfinder, which is also larger, and more focus points. Major features. | |
| Jun 26, 2013 at 8:53 | comment | added | Christian | Really thanks, Sir, for this detailed answer. I was thinking about the 7d and now I'm more secure of this choice. | |
