Bought this lens based on previous recommendations. I have to say I was concerned because I didn't know what to expect from this lens. I needed a fast telephoto lens that could be used in low light conditions where flash is not allowed. I tried it on my son's gymnastics and was very happy with his work. I still need more practice with this lens but once I understand the camera settings this lens will do the job just fine. The only thing that surprised me was its weight. It's very difficult and I had to take short breaks between takes. However, it's not stressful at all. I've attached some unedited RAW photos to see its performance. ISO 600, shutter speed 1/60s, no flash. Without any changes. Pictures taken with Nikon D7000 and with this lens: Nikon 80-200mm, f/2.8. I am satisfied with its performance.
