Summary: I have been looking for a lense for about a year and finally decided to get this. I have a Nikon D80 and this works very well with it. Pictures are fabulous, but at 400 it does have a hard time focusing and the lens is pretty heavy.
Great telephoto Lense for wildlife, but a bit soft

Summary: I originally purchase this lense for my African Safari trip in early 2012. I used it with my Canon Rebel T3i or 600D together with 3rd party battery grip. I've now used it multiple times at Africa, Montana and Galapagos. The zoom was sufficient and the lense is sufficiently fast. There's 2 IS setting and I've found that the IS works relatively well (I have nothing to compared with as this is my first lense with IS).
Summary: I have owned the Canon 100-400L and though I know it intimately from shooting many images through it and having to do field repairs, I just never fell in love with it. I think for me the push-pull zoom was just too awkward. Others love it, not me. I have had the 100-400 disassembled to remove dust and repair the focus and tension ring, so I'm not afraid of lens work, especially when at an inconvenient location for repairs.
Summary: I've compared the Sigma 120-400mm lens, and at the same time, also the Canon 100-400mm L lens (priced at $1600). I took both lenses,on a tripod, and shot numerous photos with both from the same position, different focal lengths, and on the same subjects. On comparing the photos, after downloading, couldn't see a real difference in the quality. Tried different lighting conditions, with/without uv filters, etc.
Summary: I had read mixed reviews on this lens and wasn't sure if it would be the best choice for my needs. I do mostly wildlife photography and needed a long reach lens. After driving myself crazy, I finally chose to buy it over the more expensive Canon 100-400 IS. I was amazed for so many reasons. Excellent picture quality, great features and for such a heavy lens, the incredible balance made hand holding a breeze at getting clear, crisp photos.
