    AI Servo is designed to track moving subjects. Birds in flight, a football player running across the field etc. The focus doesn't "lock" onto one area, it changes as the position of the subject moves. As long as you hold the shutter button half way down, the focus will continue to follow the moving subject.

    In the other focus modes the focus will lock onto a static subject, and not change, until you release the shutter button and depress it half way again.

    and the rest for still shots basically?

    Has anyone seen this yet?

    Youtube video ID - fbgkxRjO8TU


    The music's great (can never not like Fleetwood mac) and the video's pretty slick.. but I'm not too familiar with Embrace's products.

    This looks like a nice enough product and the price is very competitive for the features they claim. But does anyone have more detail on these guys? Anyone used their other products or have a review on this one?
