"Best lens I have bought in years. Of course, it produces great macros. But it can be used for portraits, even indoors. Portrait results blew me away." bhphotovideo.com
"I was told how good this lens is, but it is much better than they said. It is not as heavy as everyone said. i find it just as it should be. If that is a ten carat diamond it should weight like one." bhphotovideo.com
"I mainly use this lens for close-up work like insects and plants. It is ideal for a full frame high resolution sensor and is sharp from edge to edge. I can't find any faults at this stage." bhphotovideo.com
"It is fantastically sharp, fast to focus on my 350D, light and easy to hand hold. It is nicely balanced even with the 2X converter in place." bhphotovideo.com
