Reviewer score 52%The Viltrox 20mm F1.8 PFU RMBH ASPH (410 euros) scores very well or excellent on almost all criteria but fail at a very important one for a wide angle lens : borders/corners are really bad and only usable around F8. Pros Very good to Excellent sharpness in the centre Beautiful color rendition Very pleasing and soft blurry background, Very good bokeh, Reasonable price, Very good build quality, Clickless Aperture ring Very good at video No CA Very Low distorsion (you can use Zeiss Loxia 21mm lens profile as a proxy to correct it) Moderate vignetting Very good resistance to flare Well thought 2mm filter holder
