Here are five things I wish I had known about focus when I started shooting with a DSLR. Maybe I can save you from having to learn them the hard way like I did.
For those of you interested in how these videos are created, this video was recorded on the Canon 5D Mark II using a Sennheiser wireless microphone. This is a big step up from my previous videos which used a Kodak Zi8 with a wired Audio-Technia mic. The new rig costs 20 times as much as the old rig, but I think the improvement in quality is quite apparent.
I hope you find this helpful.
