Unfortunately I don't have any examples on this computer to share, but I can tell you first-hand that this is an excellent lens. I bought it specifically to bring with me to Italy this summer, and although I'd also brought 4 other lenses with me, this one never left my camera, and the results were amazing, imo, especially its color rendering. You won't regret buying the 21/4. What I love most about it is that, despite being a wide-angle, it distorts so little that it can be used in so many "normal" circumstances too. Just be sure to keep your fingers out of the frame when composing your shots!!
