Key Features:

  • Wide-Angle View: Provides a 94.5-degree angle of view on full-frame cameras, making it suitable for landscape, architectural, and astrophotography.
  • Fast f/1.8 Aperture: Excellent for low-light conditions and creating a shallow depth of field.
  • Internal Focus: The lens does not change length during focusing, and the front element does not rotate, making it easier to use filters.
  • Build Quality: Robust construction typical of Sigma's EX series, designed to handle various shooting conditions.

Performance:

  • Sharpness: Good center sharpness when stopped down to f/2.8 and beyond. The lens is softer wide open at f/1.8.
  • Distortion: Minimal barrel distortion, which is well controlled for a wide-angle lens.
  • Vignetting: Noticeable at f/1.8, reducing significantly by f/4.
  • Chromatic Aberration: Some chromatic aberration is present, especially at wider apertures, but can be corrected in post-processing.
  • Flare and Ghosting: The lens is prone to flare and ghosting, particularly when shooting into the light, despite the use of anti-reflective coatings.
