Sigma 28-45mm F1.8 DG DN Art — Editorial Review

The Sigma 28-45mm F1.8 DG DN Art is the world's first constant-f/1.8 zoom for full-frame cameras — a genuinely new optical category. Fstoppers tested it as "the world's brightest full-frame zoom," and the appeal is exactly that: prime-grade light-gathering and depth-of-field control across a short but useful range.

Featured Video Review

Sigma 28-45mm f/1.8 Lens Review: Good. Heavy. Interesting.
Gerald Undone · "Sigma 28-45mm f/1.8 Lens Review: Good. Heavy. Interesting." · Watch on YouTube

Prime-like rendering in a zoom

Dustin Abbott calls it beautifully made and feature-rich, with a high-end focus system, "incredibly sharp" results, and gorgeous bokeh and rendering. PetaPixel frames the trade plainly — "limited zoom, maximum light" — and notes it can even handle the occasional near-macro shot. In Gerald Undone's review — featured above — he sums it up as "Good. Heavy. Interesting."

Honest cons

  • Short zoom range. 28-45mm is a narrow span; this is closer to a flexible prime than a do-everything zoom.
  • Heavy. The constant f/1.8 optics make it large and dense for the focal range it covers.
  • Soft corners wide open. Corners are soft at f/1.8 and firm up considerably by around f/4; 28mm wide open also shows some lack of contrast.
  • Premium price. You pay for the f/1.8 engineering relative to ordinary standard zooms.

Where this lens fits

  • Hybrid shooters and event/wedding photographers who want f/1.8 subject separation without swapping primes.
  • Video shooters who value constant f/1.8 across the zoom for consistent exposure and shallow depth.
  • Available-light photographers who shoot indoors and at night and want maximum gathered light.
  • Not those needing a long or wide range, the lightest possible kit, or edge-to-edge corner sharpness wide open.
