What reviewers say
Reviewers praised detailed images, effective eye autofocus, the clearer viewfinder and improved grip. Both criticised complicated menus, limited touch controls and modest video improvements. PhotographyBlog found it a worthwhile upgrade; Digital Camera World thought the resolution gain needed careful technique and questioned slow-shutter handheld stabilisation. Fast action can expose the buffer and tracking limits.
