Construction

The lens barrel is made of magnesium alloy,[2] and the zoom ring will scratch after some weeks of regular use.[2]

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]

gollark: It's nice that my osmarksthings™ can freely mix "document" and "application".
gollark: I don't actually like that idea.
gollark: The web is incredibly thoroughly tested now, at least. Although also incredibly complex and plugged into too many things.
gollark: I think citrons will like this.
