Though expensive, Canon's EF 24-70mm f/2.8L USM Standard Zoom Lens is a terrific "street zoom" lens that will satisfy most photographers.
Today's highly capable digital SLR cameras require quality optics to deliver optimal results. That's why Canon supplies photographers with its L-series line of lenses. In the so-called "street zoom" category, the Canon EF 24-70mm lens covers the most commonly needed focal lengths. Moreover, it does so with a constant aperture of f/2.8 meaning this is both a fast lens that can generate a pleasing blur in the background to make your subject pop, and that it is a good companion for low-light shooting.
According to Canon:
This new lens does what many pros thought couldn't be done - replace the previous L-series 28-70 f/2.8 lens with something even better. Extended coverage to an ultra-wide-angle 24mm makes it ideal for digital as well as film shooters, and the optics are even better than before with two Aspherical elements and a totally new UD glass element. It's now sealed and gasketed against dust and moisture, and a new processing unit makes the AF faster than ever.
