Sigma 16mm F1.4 DC DN Contemporary Lens for L-Mount

The Sigma 16mm F1.4 DC DN Contemporary for L-Mount is a fast wide-angle prime for APS-C cameras, giving a 24mm equivalent view with an F1.4 aperture. It is a well-proven design that stays sharp wide open, which suits night skies, interiors and low-light street photography.

Image quality

There are 16 elements in 13 groups, including three FLD, two SLD and two aspherical elements, which keep the lens sharp across the frame even at F1.4 and hold back colour fringing and coma. Super Multi-Layer Coating cuts flare against bright light, and a nine-blade rounded aperture gives smooth background blur.

Autofocus and video

The focus group is light, so the stepping motor can move it quickly and almost silently, which suits video as well as stills. Focusing is internal, and the mount has a seal against dust and splashes.

Size and close focus

It weighs 415g and takes 67mm filters. The minimum focus distance is 25cm, for a maximum magnification of 1:9.9.

Who it’s for

On full-frame L-Mount cameras such as the Lumix S5II, Sigma fp and BF it is used in APS-C crop mode, which brings a 24MP sensor down to roughly 10MP for stills, though that matters less for video in Super 35 mode. Leica CL and TL2 owners use it on the full sensor. For a light all-round zoom on the same system, look at the Sigma 18-50mm F2.8 DC DN for L-Mount.
