I've probably made 10k+ shots with mine now, I've produced many amazing shots, it kills the FA31LTD performance wise and whilst focus can be hit and miss who is really surprised, no phase detect AF system is designed for an 18mm f1.8 lens. That said it's no where near as crap as has been mentioned and why they compare it to the 20-40/4 I have no idea, they are two completely different beasts. The flare performance is damn good for a fast zoom, again I'm not sure what they are on about.
