Review Excerpt

Excellent image quality; Improved high-ISO performance; Better JPEG quality; Fast autofocus; Very good subject tracking with real-time live view feature; All-magnesium body construction; 4K video.
Slow buffer clearing (no UHS-II support); No touchscreen, Clunky menus; Wi-Fi can be a bit frustrating to use.
