This is for all of us who want to shot (and focus) like a pro. The new Auto-Focus System on the 5D Mark III and 1D X is a complex and sophisticated beast. To harness all of its power you have to know how it works, and how to set and configure it for your purposes. Canon’s Digital Learning Center published a series of technical articles about the advanced Auto-Focus system featured on the EOS 5D Mark III and EOS 1D X.

Engineers from Canon Inc. in Japan have provided a richly-illustrated guidebook on the new 61-point AF system, which has a wealth of information about different possible settings and when to apply them. It also explores the basic characteristics of this new AF system, shows the differences that occur when various lenses are mounted, and even gives suggestions for instantly changing from one AF point or AF area mode to another. And since the EOS 5D Mark III shares nearly all aspects of its AF system, it’s equally useful for owners (or prospective owners) of that camera as well.

There is a true little gem you will find among those articles. It’s the EOS-1D X AF Settings Guidebook, which, as you already know, refers to the 5D Mark III too, since both cameras share the same AF system. You can download the guidebook clicking here (UPDATE: some users are not able to download the PDF. If it is your case, then right click the link, then “save as” the PDF. If it is still not working, head to CPN’s homepage and download the guide from there).
