Olympus is already preparing a sequel to its E-P1 that would address at least one main complaint about the Micro Four Thirds camera, according to a claim by French magazine Chasseur d'Images. Coming from the same issue that accurately leaked the Nikon S1000pj under its working codename, the assertion intercepted by Photo Rumors has an Olympus E-P2 adding a built-in viewfinder. The current model only has an optional viewfinder that needs to use the camera's hot shoe, preventing it from using flash at the same time and providing a view separate from what the lens itself sees.

Other feature upgrades if any haven't been revealed at this early stage.

The E-P1 has been heralded as one of the smallest cameras to have interchangeable lenses thanks to Micro Four Thirds' absence of a traditional, large mirror setup, but it has been criticized for lacking both a viewfinder and flash in the main camera body. Olympus has defended the design by noting that its size goal demanded removing these features. By comparison, the Panasonic Lumix GH1 has both an electronic viewfinder and flash but has a larger body closer to that of DSLRs.
