Third-party reviews

What we like about Viltrox 20mm F 1 8

  • Solid all-metal construction with high-grade build quality
  • Affordably priced compared to first-party alternatives
  • Excellent center sharpness even at wider apertures
  • Smooth and well-damped manual focus and aperture rings
  • Pleasing, creamy bokeh quality thanks to a 14-blade diaphragm
  • Innovative filter solution (includes 82mm adapter hood)
  • Well-controlled distortion and chromatic aberrations

What we don't like about Viltrox 20mm F 1 8

  • Fully manual lens with no autofocus or electronic contacts (no EXIF data)
  • Significant weight (approx. 775g) and relatively bulky size
  • Noticeable vignetting and soft corners when used wide open
  • Lacks weather sealing for protection against elements
  • De-clicked aperture ring only (no option for tactile clicks)
  • Flares and ghosting can become more defined when stopped down

Verdict

The Viltrox PFU RBMH 20mm f/1.8 ASPH is an ultra-wide, manual-focus prime lens designed for full-frame mirrorless cameras, featuring a robust all-metal build and a 12-element-in-9-group optical structure that includes four Extra-low Dispersion (ED) and one aspherical element. It is characterized by its bright f/1.8 maximum aperture, a 148.5-degree focus throw for precision, and a unique 14-blade diaphragm that maintains a nearly circular aperture for smooth bokeh. Main pros include its exceptional build quality, high center sharpness even when wide open, and an innovative dual-hood system that allows for 82mm filters despite the bulbous front element. However, it lacks electronic contacts for EXIF data and autofocus, is notably heavy at approximately 775g, and suffers from significant corner softness and vignetting when used at its widest apertures.
