Great handling with improved ergonomics Very fast and intelligent AF system Bright, sharp and high-contrast viewfinder Excellent 4K video quality Pixel Shift Multi Shot capable of superb detail Well-behaved metering system

Some AWB and focus issues Rolling shutter noticeable in videos Mode dial more awkward to access than before Touchscreen could be better No in-camera raw processing No motion correction in Pixel Shift mode

Huge resolution ; Extensive and capable AF system ; High resolution viewfinder ; Great battery life

Limited touchscreen ability ; Restricted screen angle adjustment ; No 60p option in 4K or 10bit capture ; Body not a slim as it once was
