Sony:

With the world’s first back-illuminated 35 mm full-frame CMOS image sensor with 42.4 megapixels2, the Sony α7R II takes image resolution, sensitivity (up to ISO 1024003) and speedy response to new heights. The Fast Hybrid AF system’s dense extra-wide focal plane phase-detection AF coverage keeps a subject in sharp focus entirely throughout the frame, while 5-axis image stabilization reduces blur which otherwise tends to affect handheld shots. High resolution is further enhanced by 4K movie recording featuring full pixel readout without pixel binning. With so much insight packed into such a compact form, it’s clear that there is more to life than meets the naked eye.

It’s a much bigger update than the name suggests. The α7R II is the real beast that its predecessor were not. I’ve been weighing in to get into the full-frame mirrorless bandwagon, this seems like the perfect camera to start with.
