I just got this lens about a month ago and have shot probably 10k frames...mostly with focus tracking at equine events. Last night, while at an event, i noticed the focus locking up occasionally. I did all the normal checks (switches, contacts, etc) and all looked good. Then later, it just stopped focussing altogether. I tried it on another body, etc to no avail. Has my afs engine died already? It's going back and a new one is on the way, but this really worries me on a very expensive price of glass that is supposedly professional quality...was this a fluke?
