This is the largest maximum aperture ever achieved at this focal length for a full frame platform



Pros:

  • World’s first F1.4 lens at 14mm
  • Very feature rich lens
  • Very flexible approach to controlling aperture
  • Rear filter holder
  • Excellent astrophotography features
  • HLA focus motor is fast and quiet
  • Very strong coma performance
  • Gathers more light than any such wide angle I’ve seen
  • Mostly good flare resistance
  • Low aberrations
  • Extremely sharp at smaller apertures

Cons:

  • No front filters
  • Large, heavy, and expensive
  • Not as sharp on the edges as Sigma’s recent wide angle lenses at large apertures
  • Heavy vignette
