Sigma Art 17-40mm f/1.8 DC

★★★★★ 4.8 (90)

A constant f/1.8 aperture across the entire 17-40mm zoom range delivers prime-like optical performance in a weather-sealed, 535g body. Its 11-blade diaphragm and Super Multi-Layer Coating produce smooth bokeh with suppressed flare, while the HLA motor provides fast, quiet autofocus for hybrid shooting. This lens is best for portrait and event photographers on Fujifilm X-mount who need a bright, versatile standard zoom without carrying multiple primes.

vs Competition

The competitive landscape has shifted significantly. The Sigma Contemporary 16-300mm f/3.5-6.7 DC OS now offers a massive zoom range with stabilization, making it a more versatile travel companion. The Tamron Di III 18-300mm f/3.5-6.3 VC VXD matches that flexibility with fast autofocus. On the longer end, the Nikon NIKKOR Z 28-400mm f/4-8 VR stretches reach even further for full-frame users. For those who prioritize sharpness over zoom range, the Panasonic Leica DG Vario-Elmarit 50-200mm f/2.8-4 and the Viltrox 13mm F1.4 provide specialized alternatives that outperform in their respective niches. This lens now feels squeezed from both the convenience and optical quality sides.

Price

Value & Pricing

The price range has expanded upward, now reaching $1267 for certain configurations, which makes the value proposition harder to justify. While the base price remains at $904, the higher ceiling puts it in direct competition with lenses that offer more range or brighter apertures. If you can find it near the lower end of the spectrum, it still holds some appeal, but at full retail, you are paying a premium that the current performance score of 76 does not fully support. Budget-conscious buyers will want to compare closely with alternatives before committing.

Verdict

With a revised overall score of 76, this lens now sits in a more crowded and competitive space. The expanded price range up to $1267 weakens its standing, especially when newer all-in-one zooms and specialized primes have entered the top ranks. It remains a capable optic, but the market has shifted around it. For most people, the newer Sigma 16-300mm or Tamron 18-300mm will deliver more flexibility for similar or less money. If you already own it, there is no urgent need to switch, but new buyers should look carefully at what the latest rivals offer.
