"I've used it for Portraits and for Macro and it did a beautiful job in both areas. Nice rich colors on my 5D & 7D. This lens made me fall in love with my 7D because I was disappointed with the 7D performance. Shooting macro with the 7D and Tokina 100mm macro was as easy as turning on the camera. I love this lens." bhphotovideo.com
