Excerpt: I love this lens. The f/1.8 aperture makes for some dreamy shallow depth of field, and it's excellent in low light situations. Smooth, quiet focusing is a breeze. I think I really got the most bang for my buck.
Pros: Consistent Output, Easily Interchangeable, Fast / accurate auto-focus, Lightweight
Excerpt: I used this lens mainly on portraits. The image is super sharp and the auto-focus is really fast.<br /><br />It is light, fast, and much cheaper compared with its bigger sister f1.2L.<br /><br />It provides soft bokeh when shooting at aperture wide open. <br /><br />The only thing bothers me is the fringing along highlight edges.
Pros: Fast / accurate auto-focus, Lightweight, Nice Bokeh
