Excerpt: I purchased the Sigma 70-200mm f/2.8 EX DG APO OS HSM to use on my Canon ESO Rebel T2i due mainly to the price of the Canon equivalent. After using it once I was completely satisfied with the smooth operation, the speed of the focus and clarity of the pictures. I own several Canon lens as well as other Sigmas and found this to be the one that will stay mounted most of the time.
Excerpt: I use this for portraits and it is great for low light situations. Also do runway shoots and it is great for times when I cant get closer to the models. So far the quality of images is what I expected after doing much review on this.
Pros: Consistent Output, Durable, Fast / accurate auto-focus, Nice Bokeh, Strong Construction
Excerpt: Purchased lens from B&H after reading tons of reviews. Have been extremely happy with image quality, bokeh and accurate colors, shooting handheld. If you are looking for a great lens, don't waste your money on the more expensive lenses when you can achieve great results from this 70-200. I've been using on Canon 6D and 70D. Also purchased Sigma 50mm 1.4 Art lens. Love it too. Don't hesitate. Just get it. You won't be sorry. Have a 24-70 2.8 on order. Kudos Sigma.
