Olympus promises the new flagship's continuous AF tracking performance will be dramatically improved with a new algorithm aimed at following subjects on the move. The OM-D E-M1 Mark II has a new Pro Capture Mode designed to catch split-second moments and a 50 megapixel High Res Shot Mode that apparently rivals the detail captured by full-frame DSLRs.

The Mark II also takes 4K video (4096 x 2060) and to help offset camera shake, it uses a 5-Axis Image Stabilization system and electronic stabilization specialized for movies. The camera is weathersealed, dustproof, splashproof and freezeproof to 14 degrees Fahrenheit. Its battery is improved by 37 percent over Olympus' previous flagship model and even packs dual memory card slots.
