Sigma 20–60mm F2.8–4 vs 85mm F1.2 Art: Lens & Filter Guide
Freewell Gear
FREEWELL LENS LAB / 30 SEPTEMBER 2026
20–60mm flexibility.
85mm F1.2 separation.
Sigma released two full-frame lenses on the same day, but they solve almost opposite problems. The 20–60mm F2.8–4 DG | Contemporary is built around range, mobility and an unusually wide starting point. The 85mm F1.2 DG | Art is built around subject isolation, low-light headroom and portrait rendering.
This is therefore not a conventional “which lens wins?” comparison. It is a guide to deciding which new Sigma lens better fits the work you actually shoot—and which filter size you need once it is on the camera.

01 / THE FAST DECISION
Two launches. Two very different shooting days.
CONTEMPORARY / ZOOM
20–60mm
Carry one lens and keep moving.
The attraction is not just “a standard zoom.” Starting at 20mm changes the way it fits travel, interiors, landscapes, handheld video and environmental work. Then it still reaches 60mm for normal-perspective details and loose portraits.
TravelLandscapeHybrid videoClose-upART / PRIME
85mm / F1.2
Build the frame around one subject.
This is the specialist: portraits, weddings, fashion, stage work and cinematic close-ups where the background should fall away and the subject carries the image. The trade-off is obvious—one focal length and substantially more weight.
PortraitWeddingFashionLow light
The practical distinction: choose the 20–60mm when changing position and framing quickly matters more than maximum aperture. Choose the 85mm F1.2 when the look of one focal length—and what F1.2 can do with depth, light and separation—is the reason for the shot.
02 / SIGMA 20–60MM F2.8–4 DG | CONTEMPORARY
A standard zoom that starts where most standard zooms stop being wide.
20mm is the headline. On full frame, it gives noticeably more room than a conventional 24mm starting point, which can matter in tight interiors, travel streets, landscapes, cars and handheld creator shots. Sigma then carries the range to 60mm without turning the lens into a heavy all-purpose brick.

Its close-focus performance is unusually useful for a travel zoom: Sigma lists 1:2.3 maximum magnification at 35mm, approaching half-macro territory without carrying a separate macro lens.
03 / SIGMA 85MM F1.2 DG | ART
The opposite philosophy: one focal length, maximum intent.
At 85mm, Sigma is targeting the classic medium-telephoto portrait role and pairing it with its brightest-ever 85mm aperture. F1.2 gives the photographer more control over subject separation and more light when conditions fall away.

Sigma also gives the Art lens the controls expected on a working prime: an aperture ring, aperture-ring lock, click/de-click switch and two AFL buttons. For video, the company says focus breathing has been minimized.

Specifications are from Sigma’s current product pages. Dimensions and weight vary slightly by mount on the 20–60mm. Both lenses are described as dust- and splash-resistant, not waterproof.
05 / VIDEO & HYBRID WORK
For video, the real comparison is flexibility versus depth.
20–60mm: change the shot without changing the lens
20mm works naturally for establishing shots, interiors, gimbal work and close handheld framing. Moving toward 60mm gives you a tighter perspective without stopping to swap glass. Sigma also specifically designs the lens to suppress focus breathing, which helps focus pulls look less distracting.
At 375–385g, it is the easier of these two lenses to balance on a compact rig or carry through a long travel day.
85mm F1.2: make depth part of the shot
For interviews, detail shots, fashion, weddings and cinematic portrait work, the F1.2 prime gives you a much shallower depth-of-field option. The de-clickable aperture ring is also a practical video control when you want smooth manual aperture changes.
The cost is handling: 905g before the camera, filter, cage or other support enters the equation.
06 / FREEWELL DUNNA
One filter system for either Sigma.
The Dunna Did It Ultra-Slim Locking system covers the filter options you would typically want around these lenses—ND for daylight exposure control, CPL for reflections, and Mist for a softer cinematic or portrait look. Use the builder to choose the correct base ring for your lens and add only the filters you actually need.
For the 20mm end of the zoom, keep an eye on the corners if you stack multiple filters; ultra-wide framing is less forgiving of extra thickness in front of the lens.
Build Your Dunna Kit →07 / WHICH ONE BELONGS IN YOUR BAG?
Think in assignments, not spec-sheet victories.
If you want one new everyday Sigma lens
The 20–60mm has the broader job description. Its 20mm wide end, light weight, useful close-focus ability and 60mm long end make it the more flexible single-lens choice for travel and hybrid shooting.
If portraits are the assignment
The 85mm F1.2 exists to give up zoom flexibility in exchange for a very specific rendering tool. It makes more sense when 85mm is already a focal length you deliberately reach for and F1.2 will be used rather than merely admired on the spec sheet.
One useful two-lens kit: these lenses can actually complement rather than replace each other. The 20–60mm covers wide-to-normal work; the 85mm takes over when subject isolation and medium-telephoto perspective become the point of the shot.
08 / FAQ
Quick answers before you choose.
Did both Sigma lenses launch on September 30, 2026?
Yes. Sigma’s global launch notices list September 30, 2026 for both products. Sigma America lists US authorized-dealer availability beginning October 6, 2026.
Do both lenses work on Sony E-mount and L-Mount?
Yes. Those are the two mounts Sigma currently lists for both lenses.
Which lens is lighter?
The 20–60mm is dramatically lighter: 375g for Sony E-mount and 385g for L-Mount. The 85mm F1.2 is 905g.
Which lens is better for travel?
The 20–60mm is the more flexible travel-oriented design because it covers several focal lengths in a much lighter body. The 85mm can still be a travel portrait lens, but it is a more specialized choice.
Why use ND on an F1.2 portrait lens?
In bright conditions, ND reduces incoming light so you can keep a wide aperture for shallow depth of field without forcing an excessively fast shutter or stopping the lens down just to control exposure.
What filter sizes do I need?
67mm for the Sigma 20–60mm F2.8–4 DG | Contemporary and 82mm for the Sigma 85mm F1.2 DG | Art.
Are these lenses waterproof?
No. Sigma describes both as dust- and splash-resistant and explicitly notes that this does not mean waterproof.
