Query: Super Lens

The 24-70mm f 2.8L USM is a superb Lens. Its one that every serious photographer must have in his armoury. In fact together with the 70-200 f 2.8L IS USM, they make a pair of the most useful lenses a Canon Photographer could possibly want in most situations. For one on the move, these 2 lenses will cover most requirements. Yes they are heavy; but when you want quality glass, they will weigh! With time you will easily learn to handle their weight.
