What reviewers say

Both reviews praise its portability, fast quiet autofocus and corrected image quality, while criticising the missing weather seals and hood. Digital Camera World finds effective stabilisation and strong sharpness for its price. Amateur Photographer notes softer wide-angle corners and diffraction at the smallest telephoto apertures. Both emphasise that uncorrected wide-angle images have substantial distortion and dark corners.
