What reviewers say

Both praise sharp images, compact handling, build quality, quick quiet autofocus and the aperture controls. Both acknowledge the modest aperture and price against larger alternatives. Photography Blog reports conspicuous wide-open corner darkening and some flare; Digital Camera World notes weaker wide-open corners than its 40mm sample and regrets the missing focus-distance scale.

Sony specifies two linear motors and two aspherical elements, correcting Photography Blog’s XD and three-aspherical descriptions. Maker 0.35 m AF / 0.31 m MF corrects Photography Blog’s swapped macro-section distances. No unconfirmed fluorine coating is imported
