The lens i used is the 17-40mm f/4.0 L lens because i like to do landscape photography but can also be useful in some situations. Since the 7D is a crop sensor camera with a crop factor of 1.6, i would not recommend using the 50-200mm (this lens is now essentially a 75-300mm due to the crop factor). A 24-105mm f/4.0 would be a good overall lens to use or you may want to invest in the 18-55mm f/2.8 which is not an L lens but i would classify it as an L lens since the quality is absolutely sublime. I would highly suggest you to get the 18-55mm, however; the downside is that it is quite heavy and is quite pricey for a non-L lens. Don't be put off by the price though because you are essentially getting a 24-70mm f/2.8 L in disguise
