Olympus OM-D E-M5
Unveiled in February 2012, the Olympus OM-D E-M5 was Olympus' first Micro Four Thirds system camera model to be designed with a permanently integrated (electronic} viewfinder. Complementing the Olympus 'Pen' family of cameras without built-in viewfinders, the new OM-D category represents Olympus Micro Four Thirds camera models designed with built-in finders. As the name implied, Olympus once again resorted to nostalgia by creating a brand based on its film SLR heydays. First there was the digital 'Pen' brand and style based on Olympus' compact half frame film SLRs from the 1960s and then the OM-D (OM-Digital) brand borrowed from the 1970s OM 35mm film SLR system.
