I recently purchased a Canon 60D and went with a 16-35 2.8 L series lens. My reasoning behind buying this lens was that I needed something that was wide angle to start with, plus I was able to get it at a very low price used (and on a side note, I would need to shoot some stills periodically). Is this lens in any way adverse to being used for video? I read a bit of info on the forum that stated that sigma lens are more suited to DLSR video than high end Canon lens. Could someone please provide some insight on this topic?
