With the ultra-wide view of a 20mm lens, you're free to capture expansive landscapes and architecture, wedding parties, an entire band on stage, crowd shots and much more. Add low-light capabilities to that view, and the shooting possibilities are nearly endless.

Its lightweight ...compact in size...pretty quick to focus and its sharp. I really like how the glass renders the images, color and contrast are very nice. Little to no distortion as well. I wanted to go with the ultra-wide zooms but...if you want to use a ND filter set..

This is an astounding lens. I sold my 16-35mm f/4 for it and Im not regretting it for a minute. Its better in pretty much every regard (apart from the obvious lack of zoom). Ithits all the marks, including some aspects that are not always covered in reviews, but are important to me for landscape...
