Background and Identification
Sony's Alpha 7R II is the world's first 35mm full-frame back-illuminated sensor camera. The a7R II takes 42.4 MP stills, 4K video, and goes up to ISO 102,400. It features a 5-axis motion processor to support its advanced optical image stabilization system, as well as a new, hybrid phase-detection autofocus system with 399 autofocus points. Like most competing systems, the a7R II has Wi-Fi to support wireless tethering and data transfer, while incorporating NFC technology for "one-touch connection."
