Viltrox AF 27/1.2 Pro Z 27mm

92 out of 100 medium confidence 20 reviews

The Viltrox 27mm F/1.2 Pro lens receives overwhelmingly positive feedback for its exceptional sharpness, beautiful bokeh, and solid build quality with weather sealing.

Overall, it is considered a fantastic value that rivals more expensive options.

Pros
  • Exceptional sharpness even at f/1.2
  • Beautiful bokeh and subject isolation
  • Solid build with weather sealing
  • Great low-light performance
  • Superb color rendition and contrast
Cons
  • Heavy and bulky design
  • Autofocus lag with moving subjects
  • Large size may feel unbalanced on small bodies
  • Crop sensor lens only (not for full frame)
