Re: 5D AF sucks---see examples

Well, those are nice photos, congraduations, but it says nothing about the AF. You probably have about four feet of DOF at F4, so critical focus isn't really important (plus w/that photo size you can't really tell if you have critical focus.) You have lots of contrast at the center, and the subjects are dead centered, piece of cake for any dSLR really.

Now, try a upper body shot of gymnast at F1.4 indoors running towards you : ) A few inches of DOF, over 10 times more critical. Things get sticky very quickly. I know, I know, repeat after me, the 5d isn't a sports camera.

Those were taken with 70-200 F4, right ?? So, good photos, but no need to get defensive about the AF. If it's good enough for you that's great.
