Canon

The Canon EF 17-40mm F4.0L USM has been on the market for many years now, but remains popular with Canon photographers using both full-frame and APS-C DSLRs (on which it covers an equivalent focal length range of 27-64mm). An extremely tough and compact lens, the 17-40mm does not get any larger when zooming or focusing, and the inclusion of three aspherical and one Super UD (Ultra-low Dispersion) elements result very good image quality across its focal range. This lens is weather-sealed, and a ring-type ultrasonic focus motor provides fast and silent AF with full-time manual focusing.
