Not the most comprehensive test of a lens ever, but I had just put it on my 550D after buying it on ebay.

Since this footage I have done some serious filming with it in amongst my other lenses. I have to say that it can be matched well to my sigma 17-50 f2.8 and my Nikon 35mm f2.5. Sometimes it lacks a bit of contrast in daylight outdoors but this can be added back in post. Its an amazing lens which holds up against canon L series lenses for sharpness IMO, and for £70! You can get them even cheaper than this as well.
