 Do you need the faster aperture because you are shooting in low light conditions such as wedding ceremonies or in areas that flash and strobes are not allowed? Looking for a mid-range zoom with the lowest possible distortion? Then the Canon EF 24-70mm f/2.8L USM is perfect for you. & n6 W0 \2 k# Y6 o

 If you’re looking for a single lens that is light, very versatile, and with IS, then the Canon EF 24-105mm f/4L IS USM is for you. It doesn’t lock focus as fast as the f/2.8 in low light conditions, but it comes very close.

 For your case, 60D is a very good but not a full frame, 24-70 may be a better choice which costs your a bit more money.
