The range, weight, and handling are good. However the image quality is severely lacking. The bokeh is ugly if you have bright lights in the frame. Corner sharpness from 16-22mm is absolutely horrendous at anything below f/8, and that's not on a pixel level, it's noticeable on 3x5 prints and web images. It's not a pleasing effect either, I took the lens to shoot a family event for a friend that had 5 people in frame and the faces of the people on the ends were blurred horizontally. Another large issue: fringing and chromatic abberations at every aperture. Best thing I can say is the colour rendition is great and the center is sharp at every aperture. But with those other issues I cannot recommend this lens for anything other than casual use.
