From 20mm to 60mm: I Test Sigma’s New Full Frame Compact All-Rounder

Sigma is adding an interesting new option to its full frame mirrorless standard zoom lineup: a lens that combines a 20mm wide angle starting point with a compact, lightweight design. The idea was to create a versatile zoom that can stay on the camera most of the time, reducing the need to carry multiple lenses or constantly stop to change them. That makes it particularly appealing for travel, hiking, street photography, and anyone who wants to keep their camera setup as light and mobile as possible.

Sigma says the lens is its smallest-ever zoom for full frame mirrorless cameras. Despite covering an ultra-wide 20mm, it has been designed with a slim 72.2 mm diameter and measures just 86 mm on L-Mount and 88 mm on Sony E-mount. The weight is 385 g for L-Mount and 375 g for Sony E-mount.

The small form factor comes from the optical design. Sigma has incorporated high-refractive-index lenses with a high thickness-to-diameter ratio, allowing it to achieve the 20mm wide end without the lens becoming unnecessarily large. The design follows some of the thinking behind the popular Sigma 18-50mm f/2.8 DC DN | Contemporary, which has become well known for balancing both size and optical performance. I used this lens extensively on my Fujifilm X-T5 and was really impressed with its performance in every situation.

Versatile Close-Up Performance

There is more to the lens than simply being a lightweight travel zoom. It also offers impressive close-focusing capabilities, with a minimum focusing distance of 15.8 cm at 28mm. Maximum magnification reaches 1:2.3 at 35mm and 1:2.9 at the telephoto end. For photographers, that adds another useful dimension to the lens, allowing everything from expansive landscapes to detailed close-up subjects without reaching for another lens.

Optically, Sigma has used three aspherical elements and three SLD glass elements, with the company promising consistent sharpness across the zoom range. Despite the emphasis on keeping the lens small and light, Sigma says there have been no compromises in image quality.

Designed for Stills and Video

The lens is also aimed at hybrid shooters. It uses Sigma’s HLA (High-response Linear Actuator) autofocus system, providing fast and quiet focusing with strong tracking performance. The optical design also minimizes focus breathing, making it more suitable for video work. Combined with its compact size and low weight, this should make it an interesting option for handheld and gimbal shooting. The lens also features a dust- and splash-resistant construction, with sealing around the mount and other areas, along with a water- and oil-repellent coating on the front element. As always, Sigma makes clear that the lens is dust- and splash-resistant rather than waterproof.

Time With the Lens

I was able to spend a short time testing the Sigma 20-60mm f/2.8-4 DG | Contemporary, and you immediately notice how compact and versatile it is. The 20mm wide end proved useful for capturing broader scenes, while the 60mm end gave me enough reach to zoom and compress the perspective when needed. The sharpness was consistently impressive, and its relatively small size makes it an appealing option when you want a single lens that covers a useful range without adding too much bulk to the camera bag. I encountered no issues whatsoever during my time with the lens, except for the inclement weather, which ultimately hindered my ability to get out with it more. Does that mean you can't go out in the rain? No. But it was torrential, so I avoided it.

It would also be remiss of me not to mention the new packaging of the lens, which I really quite liked. Yes, it's still a box, a strong box at that, made of recycled paper/cardboard. Will this make you purchase the lens? Of course not, but it's the small details that go into everything that make you enjoy your purchase even more. Attention to detail has even been taken in the packaging.

Overall

Sigma appears to be targeting photographers who want a genuinely versatile full frame zoom without the usual weight and bulk. Starting at 20mm gives it a useful advantage for landscapes, architecture, and travel, while the close-focusing capability and video-oriented features make it considerably more flexible than the term standard zoom suggests.

With its combination of 20mm coverage, compact dimensions, low weight, and close-focusing capability, this looks like an interesting addition to Sigma’s full frame lineup, particularly for photographers who would rather spend their time shooting than changing lenses.

The lens will be available for purchase early October, and you can preorder your lens here.
