Canon EF 17-40mm f/4L USM Ultra Wide-Angle Lens
A new and affordable L-series ultra-wide-angle zoom lens that's ideal for both film and digital SLRs. Superior optics are assured by the use of three Aspherical lens elements, in addition to a Super UD (Ultra-low Dispersion) glass element. Optical coatings are optimized for use with digital cameras. This lens focuses as close as 11 inches (0.28m), and offers both Canon's full-time manual focus and a powerful ring-type USM for fast and silent AF. It has a constant f/4 maximum aperture, and offers the choice of screw-in 77mm filters or a holder in the rear of the lens for up to three gel filters. Finally, it offers weather-resistant construction similar to other high-end L-series lenses.
  • L-Series Designation
    Canon's legendary L-Series line-up signifies ultimate build quality.  Using Canon's finest optics for sharpness, these lenses also have faster focusing motors, better Image Stabilizers and are built to be used day in day out for many years.
     
  • Durability
    High performance, water-resistant and dust resistent internal seals.
     
  • 3 High-Precision Aspherical Elements
    By using 3 asperical elements, the Canon EF 17-40mm f/4L USM lens combats chromatic aberration.
     
  • 1 Ultra Low Dispersion Element (UD)
    Using 1 UD glass element the Canon EF 17-40mm f/4L USM lens has improved edge to edge sharpness.
     
  • Ultra Sonic Motor (USM) and M/A Focus
    Canon's Ultrasonic motors are designed to be faster focusers so you won't miss the shot.  The M/A (auto focus with manual override) ring allows you to fine focus your shot while still in auto focus mode.
