The new Canon 1D X Mark II was just announced by Canon this week and already there are several photographers publishing reviews (both written and video) of the top of the line camera.
The camera builds on the tank-like build of its predecessor and adds things like built-in GPS and the ability to shoot 4K video. Available in April for $5999 (body only), this camera is made for photojournalists and sports photographers in the harshest conditions.
Listen to the camera shoot at 16fps in Live View mode (no mirror movement) and then in normal 14fps with mirror movement. Exceptionally fast.
