What reviewers say

Both praise sharp images, compact handling, build quality, quick quiet autofocus and the aperture controls, and favour its versatile angle of view. Photography Blog reports conspicuous wide-open corner darkening and some flare; Digital Camera World finds shading practically absent in its shooting. Digital Camera World also regrets the missing focus-distance scale.
