"Seems like a pretty good lens. Picture is clear from what I've seen. I use it mostly for film on my Canon T2i. Does get a little blurry at 300 zoom. But overall I am satisfied with the purchase." bhphotovideo.com
"I bought this lens to take pictures of my sons select soccer games, with my f/5.6 lens the pictures would have a blur. The pictures I took this weekend are unbelievable. There was no blur and I took about 300 photos over two days." bhphotovideo.com
