"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
"Top notch lens without any real weakness, great for portraiture, landscapes, sports and more. Very Sharp, exceptional full-metal build." bhphotovideo.com
"It provides outstanding sharp photos at long distances; with the f2.8 stopping action (surfers; shore objects from a ship a mile or two off shore). I have used it at sporting events and have even used it for some astronomy work (great for the moon)." bhphotovideo.com
