Review Excerpt

Excellent 5-axis sensor-shift image stabilization; Sensor-shift IS brings stabilization to nearly any lens; Much-improved ergonomics and top-deck control layout; 'Mark II' maintains same impressive image quality, dynamic range and high ISO performance; XAVC S 50Mbps video format; Faster start-up time; Hybrid AF performs well with good continuous AF.
(Similar to A7): Loud shutter (but electronic first-curtain helps); Battery life could be better; Low-light AF still not as good as most DSLRs; High ISO JPEGs look over-processed; Slow buffer clearing; Limited selection of native Sony FE lenses (but it's getting better).
Read our Sony A7 II Review

Impressive image quality; Sleek design; 4K video recording; Good overall performance; Tilting touchscreen; Enjoyable user experience.
No EVF; No hot shoe, Short 4K clip limit; MicroSD card slot, Poor battery life.
