It's no mistake that both Nikon D5 and Canon EOS 1D X Mark II have arrived in 2016. It's an Olympic year after all, with pro sports photographers seeking next-level kit to take next-level images in Rio.

New autofocus system is insanely good; super-fast 12fps burst with decent buffer innings; detail at high ISO settings is incredible; epic battery life

The "Hi" ISO settings are roughly pointless; some odd auto white balance decisions in mixed lighting; continuous shooting undercut by Canon 1DX II
