What reviewers say

Both reviews praise central sharpness, subject separation and construction, but find the heavy body awkward and miss stabilisation. Their corner results disagree. OpticalLimits finds excellent wide-angle performance with softer corners at 70mm; Digital Camera World sees disappointing corners at 28mm. OpticalLimits also notes strong raw vignetting and focus breathing, limiting its appeal for video.
