As the title says really.

I'm after a tele-zoom to go with my existing lens (Sigma 17-70 F2.8-4) on my 60D. I'll be using it for a range of things as i haven't really got a style as yet. I'll be doing sports, wildlife, portraits and anythgin else that I have a play with.

The 3 main lenses that have caught my eye are Canon 70-200mm F4 IS L, Canon 70-300mm F4-5.6 IS L, Sigma 70-200mm F2.8 EX DG OS HSM.

Are there any others I should look at and which would be your pick?

Thanks
