Canon EF 24-70mm f2.8L USM

Manufacturer Description

The EF 24-70mm lens does what many pros thought could not be done - improve the previous L-series 28-70 f/2.8 lens with something even better. Extended coverage to an ultra-wide angle 24mm, improved optics with two Aspherical elements and a UD glass element make it ideal for digital or film shooters. It's now sealed and gasketed against dust and moisture, and the processing unit makes the AF faster than ever.
