Sigma AF 20mm f/1.8 EX DG RF (FX) - Review / Test Report

photozone.de
11 October 2007
  • Conclusion: Just like its slightly longer sister lenses, the Sigma AF 20mm f/1.8 EX DG leaves us with mixed feelings. The center resolution of the lens is very good to excellent, while the borders and corners disappoint especially at large apertures. Vignetting is very pronounced wide open. CAs and distortion are well under control, especially for such a wide lens.

Sigma AF 20mm f/1.8 EX DG RF (DX) - Review / Lab Test Report

  • Conclusion: Just like its slightly longer sister lenses, the Sigma AF 20mm f/1.8 EX DG leaves us with mixed feelings. The center resolution of the lens is very good to excellent, while the borders and corners disappoint at large apertures. Stopped down, the resolution is very good across the DX frame, though.
