What reviewers say

Photography Blog and Cameralabs praise the stabilisation, accessible controls and detailed low-ISO photographs, while finding noise prominent at higher sensitivities. Their dust-removal experiences differ; Photography Blog found its samples remained clean, whereas Cameralabs saw dust marks. Photography Blog also notes the loud shutter, while Cameralabs found the kit lens soft in the corners at wide angle.
