I'm always reluctant to purchase accessories for my Canon cameras that are not the Canon brand, but took a chance on this Sigma lens after it was recommended by a friend. I spend last weekend at Merritt Island National Wildlife Refuge and Viera Wetlands in Melbourne photographing birds. I got consistently sharp pictures, whether the subject was still or in flight. I had read on other websites that there were complaints about the weight of this lens, however, I did not find this to be a problem. I am female, 59 years old and hand held the camera most of the time, even while hiking, with no problem at all. Previously I was using a Canon 400mm lens and this lens is far superior.
What's great about it: Sharp, clear pictures even without the use of a tripod. Price was right!
