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.
