Every now and then someone comes out with a product that really makes me say, "why didn't I think of that?" If you've ever been on the set of a serious movie production, you know that the camera operator or steadicam operator hardly ever focuses the lens himself. Instead he relies on a well paid focus puller who can perfectly eyeball every focus distance and follow focus any lens set on any aperture. It's really amazing to watch. Well now a company called Okii has developed a USB focus puller for Canon cameras that can not only pull focus but also record and save a specific movement. I have no idea why they did not include audio on this video but if you watch if you can see two different points of focus being saved and then automated. It's amazing what you can find when your favorite tech blog forces you to change over to Engadget :)
