A few weeks before Christmas I was directing a still shoot and a television commercial in LA. My new 5D had not yet come in, but I was able to rent one. This is a little compilation of that test. With the exception of the night stuff and the final scene with the kids, it's all handheld. The last shot, which I shot on sticks with a good head looks the best. That's definitely the trick. Either locked off shots with minimal focus pull, or you need additional equipment, which is out there.
SPECS: Canon 5D Mark II. Canon 70-200mm F2.8. Lensbaby Composer.
