The Micro Four Thirds parade marches on as Olympus has just unleashed the details about the follow up to the E-P1 we like so much. The camera body itself hasn't seen much of an upgrade. It boasts the same 12.3-megapixel Live MOS sensor as its predecessor and those hoping for a built-in flash are bound to be a little disappointed. But, each E-P2 will come standard with an articulating VF-2 electronic viewfinder to occupy the hot shoe. It works in conjunction with an "accessory port" that's new to the E-P2. While it opens up new possibilities for this camera, it also means that E-P1 users hoping to grab the viewfinder as a standalone will be out of luck. The accessory port can also be used for an external microphone using an EMA-1 Microphone adapter.
