I got my Lytro light-field camera a couple weeks ago, and have been trying it out. It's still magical, being able to refocus. The camera's sensor is okay — poor in low light, occasionally lacking crispness — but one area where both the camera and the refocusing shine is macro. The camera can focus at the end of the lens; above, Tinysaur was lying against the glass. And once an all-in-focus mode is available publicly (I saw a preview on the Boston photo walk), macro will be that much better.
