I'm trying to think how I would use it. I, like everyone else, use shallow DOF to emphasize different aspects of the image.<p>If I want to emphasize background and foreground in different shots I just take two shots at different focus points.<p>If I want everything to be in focus I stop down the lens.<p>I have to agree with the dpreview: what artistic problem does this solve?<p>I can think of a contrived example where there is no time to make two shots (a basket ball player shooting a hoop) and where you want two parts of the image at different distances both in focus and the rest blurred. You could do it with this device, but I would just use image manipulation.<p>What I would really like is the blade runner camera (or rather dataformat) since the blade runner picture seems to be a composite of many shots.
