Olympus is hoping that the new OM-D E-M10 will find favour in the same way as the OM-10 did when it was launched way back in 1979. Whereas the OM-10 was the first consumer-level camera in Olympus's OM series of SLRs, and went on to be a big hit and a popular choice for family photography, the Olympus E-M10 is the first consumer-level model in the highly-respected OM-D series. It sits below the Olympus OM-D E-M5 and Olympus OM-D EM-1 in the company's line-up of Micro Four Thirds compact system cameras.For those unsure of the difference, the Olympus OM-D series distinguishes itself from the Pen series (Olympus Pen E-PM2, Pen E-PL5 and Pen E-P5) by its more SLR-like styling and the presence of a built-in electronic viewfinder (EVF).FeaturesMany of the features found in the E-M10 are the same as in the Olympus E-M5, the original OM-D. The Four Thirds type (17.3x13mm) 16.1-million-pixel LiveMOS sensor and 1,440,000-dot electronic viewfinder, for example.
