Sigma dp2 Quattro
The dp2 Quattro’s oddball shape is easy to hold, though it also sacrifices a degree of compact portability. But its most important feature is the radically different 29-megapixel imaging sensor, which does away with color filters for a boost in detail. Because of that, this camera is an ideal choice if you want to crop into photos or print in large formats. [$999; sigmaphoto.com]
