I'm looking to buy a tele zoom, and was set at the amazing Canon 70-200/2.8 II, mostly for shooting indoor/concert type photography. But since its such an expensive lens I thought I'd check if there are any alternatives.
After reading up on lenses, the Tamron 70-200/2.8 Di VC stood out. According to DxOMark it has even slightly better optics than the Canon, and reading through user reviews it seems to have a fast and accurate AF. At ⅔ of the price.
Can anyone shed some light on these two lenses? Is the Tamron comparable? Preferably someone who has used both or done a bit more research than I have :)
