I had one for a short while, traded it for a Tokina ATX 400 5.6. The Sigma was a fine lens and was quite sharp even wide open. I was lured by the small size of the Tokina, but the Sigma is sharper wide open and focuses closer. Build quality seemed fine to me, and it had some nice features like a focusing limiter switch and AF/MF clutch. It's also gotten pretty good reviews. The only drawback is the size, but it's not outlandish for a 400mm.
