Olympus is working on a new version of its flagship Micro Four Thirds camera, the OM-D E-M1 Mark II, which sports a high-speed TruePic VIII Image Processor that's 3.5 times faster than previous editions. The new camera also includes a 20.4 megapixel Live MOS sensor and an electronic shutter, allowing it to take full-resolution images at 60 frames per second in AF and AE lock, and up to 18 frames per second with continuous tracking.
