One of the most unusual DSLR designs I've shot with in the last few years has to be the 8.2MP Olympus Evolt E-300. It arrived about a year and a half ago, with a unique flat top look, off-centered optical viewfinder, and innovative side swivel mirror system. But it was up against stiff competition from Canon, Konica Minolta, Nikon, and Pentax models—all with more lenses to offer and better AF systems. As a result, the E-300 didn't do as well as expected, and when Olympus switched back to a more traditional design in last year's Evolt E-500, most of us thought the flat top era was over. But it appears the Olympus engineers had something up their sleeves when they designed the E-300. That something was a live LCD preview mode—a first for a DSLR. But they had to wait a few years for the price of sensors and large LCD monitors to drop in order to make the E-300's successor affordable.
