After being announced in September, Olympus' OM-D E-M1 Mark II quickly became one of the most anticipated cameras of the year. The new flagship mirrorless, which will hit stores in December for $2,000 (body only), is loaded with high-end specs. That includes a 20.4-megapixel Live MOS sensor (Micro Four Thirds), a dual quad-core Truepic VIII image processor, 121-point autofocus system and in-camera stabilization. Above all, though, the E-M1 Mark II is about sheer speed, featuring 18-fps shooting with continuous autofocus and autoexposure enabled, or an insane 60 frames per second if those settings are locked. While I've only been testing the camera for little more than a day, all of those specs have translated well in real-world use.
