Announced alongside the headline-grabbing 85mm F1.2, Sigma’s 20-60mm F2.8-4 DG Contemporary is the quieter and, for a lot of photographers, the more genuinely useful of the pair. It is a compact standard zoom that starts at a proper ultra-wide 20mm — and it is tiny. Details are on Sigma’s site.
The 20mm wide end is the point
Most standard zooms start at 24mm or 28mm, which is fine until you are indoors, in a tight landscape spot, or trying to fit a building in, at which point those few millimetres matter enormously. Starting at 20mm gives you a genuinely wide field of view in the same lens you use for everything else, which for travel and everyday shooting removes the need to carry — or switch to — a separate ultra-wide.
The trade-off is at the long end: it stops at 60mm rather than the more common 70mm, and the aperture ramps from f/2.8 to f/4. That is the compromise that buys the wide starting point and the small size, and for the intended audience it is a sensible one — 60mm still covers a short portrait, and f/4 at the long end is workable in most light.
Genuinely pocketable
The headline is the size. At around 2.8 inches long and roughly 385g in L-mount form, this is palm-sized — the sort of lens that makes a full-frame body feel like a camera you actually want to carry rather than one you talk yourself into bringing. For anyone who bought a compact full-frame body precisely to travel light, a standard zoom that does not undo that decision is exactly the point.
Despite the size, the specification is not cut back. The optical design runs 15 elements in 13 groups, including three aspherical and three SLD glass elements, with flare and ghosting said to be well controlled. Autofocus uses Sigma’s HLA linear motor system. And it has a genuinely useful close-focus ability — a minimum focusing distance of 15.8cm at the wide end, giving up to 1:2.3 magnification at 35mm and a still-high 1:2.9 at 60mm, so it doubles as a semi-macro for details without a second lens.
It is dust- and splash-resistant, with a 67mm filter thread that keeps filters affordable.
Our take
This is an easy lens to like. At £749 / $849 it is sensibly priced, it is small enough not to defeat the purpose of a compact body, and the 20mm wide end plus strong close-focus performance make it more versatile than the modest-sounding zoom range suggests. As a one-lens travel option on an L-mount or Sony E body — a Panasonic S9, a Sigma BF, a compact Alpha — it makes a strong case.
The obvious caveat is the variable aperture: f/2.8-4 is not a fast lens, and anyone wanting shallow depth of field or low-light capability at the long end will find it limited. But that is not what this is for. It is a light, wide-reaching, do-most-things zoom, and on those terms it looks very well judged.
