Officially released: Sigma 18-50mm f/2.8 DC DN Contemporary lens for Canon RF-mount

As already reported earlier, Sigma officially released their 18-50mm f/2.8 DC DN Contemporary lens for Canon RF (the lens has been available for Sony E and Leica L Mounts since 2021 and for Fujifilm X mount since last year). This is one of the first six Sigma APS-C lenses (no full-frame lenses for now) that will be available for Canon RF-mount (see the full list here).

Key Specs of the Sigma 18-50mm F2.8 DC DN Contemporary Lens for Canon RF

  • Smallest and lightest F2.8 standard zoom for crop-sensor mirrorless cameras (as of Oct. 2021).
  • Three high-precision glass-molded aspherical elements provide superb optical quality.
  • In-camera aberration correction eliminates optical distortion and vignetting.
  • The thermally stable composite barrel construction (polycarbonate with thermal characteristics similar to aluminum), with slim internal metal parts, offers lightweight and functional strength.
  • 7 rounded aperture blades offer smooth background blur (bokeh).
  • Stepping motor provides swift, accurate, and quiet autofocus for still and video shooting.
  • Working distance of just over an inch (2.7cm) from the front element at 18mm.
  • It includes a petal-type hood to reduce ghosts and flaring while protecting the front lens element.
  • High-precision, durable brass bayonet mount with dust and splash-resistant structure.
