well last night I was uploading new pics and my cat knocked over my camera and it fell only 1 foot. it landed on the corner of the lens. I picked it up to inspect it and well Know that you can not the sigmas from a foot. right above the aperture ring snapped and is hanging by a thread together. It only a year old and I hope they will warranty it. there are no impact marks at all. And I need a wide angle lens for a upcoming bike shoot in a studio and my 70-200 is way to big for this. dang my luck and all my friends use canon
