What reviewers say

Reviews praise handling, subject tracking, stabilisation and low-light image quality. Both find eye-controlled autofocus useful, though Amateur Photographer prefers conventional tracking for erratically moving birds. Photography Blog criticises the mixed card slots, while Amateur Photographer notes less cropping flexibility than higher-resolution rivals; the modest resolution also keeps files manageable.
