It is a new digital camera type that will be brought to market some time in the fall. Apparently they have played around with the light sensors so that a ton more information is collected with each photo. What this allows the photographer to do is set the focus AFTER the shot has been taken. I played around with the photos at the above link and if this camera truly works the way the gallery does I'm gonna be saving up for one of these puppies!
