What reviewers say

Both praise the detailed images, dynamic range, fast viewfinder autofocus and secure handling, finding it versatile for landscapes, weddings and action. Both criticise slow live-view focusing and awkward SnapBridge connectivity. Photography Blog also finds the settings banks cumbersome and video options limited.
