Optical properties
The lens has significant distortion at 18mm and 35mm, but less so at other focal lengths.[3] Similarly, lateral chromatic aberration is particularly noticeable at these focal lengths, and increases as the lens is stopped down.[3][4] While center sharpness is high at all focal lengths, there is strong fall-off towards the edges and corners, particularly at 18mm.[3][4] Neither edge nor center performance improve much at other focal lengths.[5] Coma is well-corrected,[6] but "when it comes to flares, the Sony E 18–55 f/3.5–5.6 OSS fails spectacularly", according to reviewer Symon Starczewski of LensTip.com.[7] Optical stabilisation gives a benefit of two stops.[2]
