Excerpt: Outdoor and Wildlife Photography. Lens has done great in all outdoor conditions. I shoot a 7D and the video has been good, hard to move and focus while shooting. <--(only Con I have) Was contemplating between this and the 2.8L IS II and have been satisfied with my decision thus far.
Pros: Consistent Output, Durable, Fast / accurate auto-focus
Excerpt: I use it for Outdoor and Wildlife Photography.The Clarity it provides to the Photos cannot be explained..its that much BEST. As far as I have used, I do not have anything to write which are not great about it..
Pros: Consistent Output, Durable, Easily Interchangeable, Fast / accurate auto-focus, Lightweight, Strong Construction
Excerpt: I shoot wildlife of all kinds, including birds. Birds move at the speed of light and I was looking for a lens that could move quickly, autofocus instantly, so I could get the shot. I love the speed of the autofocus. It's fast. I'm older (67) so I'm not as "stable" as I used to be. Consequently, the stabilization factor in this lens counteracts my age and allows me to shoot clear, clean shots. With age, weight becomes a consideration.
Pros: Consistent Output, Durable, Fast / accurate auto-focus, Lightweight, Rugged, Speed Autofocus, Strong Construction
Excerpt: This lens is incredible in every way - super sharp, great DOF, and much smaller and lighter than its f2.8 counterparts. However, in the end it could not compete with the speed and new optics of the f2.8 ver2, so I returned it and made the upgrade. But for the money and if you're not planning to show in any low light, this lens is a great value and makes beautiful images.
