Mirrorless cameras strive for big-camera quality in a little package, and reviews say the Olympus OM-D E-M5 does this better than any other camera. Like big digital SLR (single-lens reflex) cameras, the Olympus dishes up terrific image quality, a pro-grade metal body and plenty of interchangeable lenses. But since it's a Micro Four Thirds camera, those lenses -- and the Olympus' slim, retro-styled body -- are substantially smaller and easier to carry than a bulky DSLR.
Throwback style with modern conveniences. Retro style sets the Olympus OM-D E-M5 apart -- it looks like an old-fashioned film SLR camera. This throwback styling conceals two modern conveniences: an electronic viewfinder and a tilting, 3-inch OLED touch screen. With a body about the size of an index card and just 1.7 inches thick, the Olympus OM-D E-M5 saves a lot of bulk over a DSLR. There's still room for plenty of physical buttons and dials (which some consider to be too small), much to the delight of professional testers who demand full controls at their fingertips. One drawback is that even pros find the Olympus time-consuming to set up, partly because you can customize just about every button on it.ProsCompact and easy to carry, Speedy performance with DSLR-like image quality and controls, Tough magnesium body is dust- and splash-proof, Biggest lens selection in its classConsContinuous autofocus balks at tracking moving subjects, No ISO 100
