"This lens is a great fast focusing, sharp lens. I have been using this lens to take bird photos for the last few weeks and it does a marvelous job. The greatest advantage of this zoom is its size. It breaks down to being only a 1/4 inch longer than my 18-55 zoom kit lens. I also like that is allows manual focus with AF on." bhphotovideo.com
