It's a great little lens for stills and video. In a shoot out at 2.0 with a 50L, this lens is just a tad softer (hard to see in some scenes) but has dramatically less CA. The bokeh's very busy, but you can't have everything for this price.
Pleasing image quality from 2.0 on up; ok auto focus
Bokeh is a busy; but to be expected at this price
