20mm F2 DG DN Contemporary - L Mount

SIGMA 20mm F2 DG DN CONTEMPORARY LENS - Silver


This ultra-compact, wide-aperture prime lens for L-Mount systems is a game changer for
mirrorless users needing a sharp, wide-angle optic that isn't going to weight them down.

This portable, full-frame premium compact prime for mirrorless cameras is the seventh lens in SIGMA's fast-growing I series
line-up, combining a bright maximum aperture of F2, an ultra-wide 20mm focal length and stunning optical performance.

It's also the widest lens in the range so far, opening up new photographic possibilities for I series users.

The lens boasts an exceptionally small form factor, weighing in at just 370g and measuring just 72.4cm in length, which makes it a
highly practical optic that is portable enough for everyday shooting.
It's ideal for
   - landscapes,
   - wide-angle portraits,
   - weddings,
   - interiors,
and is particularly well-suited to astrophotography owing to its very well-controlled sagittal coma flare.

It's the fourth I series lens with an F2 aperture, joining a 24mm, 35mm and 65mm, which together make a well-matched lens set for
photographers who need both performance and portability in their kitbag. Remarkably, the 20mm F2 DG DN Contemporary is almost identical in
size and weight to the SIGMA 24mm F2 I series.

Its sleek, all metal design, with a signature I series magnetic lens cap, a manual aperture ring and exceptional build quality makes using this
lens is a highly intuitive and satisfying experience.
