After being announced in September, Olympus' OM-D E-M1 Mark II quickly became one of the most anticipated cameras of the year. And for good reason. 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.
