What reviewers say

PhotographyBlog and Digital Camera World praised image quality, tracking autofocus and detailed 4K footage, but criticised dated controls, limited screen visibility and absent stabilisation. PhotographyBlog found tracking exceptionally dependable; Digital Camera World saw brief losses with deliberately difficult fast subjects. Both considered the forward-facing screen useful, although shoe-mounted accessories obstruct it.
