I spent a great deal of time researching and reading reviews, considering Canon 24-70, 24-105 L lenses, as well as the Sigma 17-50. I ruled out the Canon lenses due to their price and not wanting to lose the wide angle of 17-24 - better on a crop sensor, despite having a wide angle lens 10-18mm. I ruled out the Sigma 17-50 as I didn't want less focal length to play with and although it has a constant aperture of 2.8 I was happy to give this up. Part of the decision was due to my other lenses a Canon 50mm 1.8 and the Canon 10-18mm. Knowing I have the 50mm 1.8 helps make up for the varying aperture of this 17-70.
The lens comes with a lens hood and front and back caps. I read lots of reviews saying this lens isn't sharp at the edges, but have seen no such issues - compared to my 50mm 1.8, 18-55mm kit lens and 10-18mm this appears to be producing the best photos overall.
