Web Pricing - Why are the prices on this web site different from those in your stores?
Our stores are staffed with a wide variety of product specialists and support staff, each of whom make an effort to be responsive and pleasant to deal with. We're also able to provide a customer with any item from our inventory to inspect and test. The cost of this customer service is an increased overhead for our in-store prices, to pay for the store space, the training of our employees, and other considerations not present online. We're happy to offer reduced prices online and hope that you will be satisfied with your purchase no matter where you decide to buy.
The Canon EF 17-40mm f/4L USM Lens is 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.
About half the price of the 16-35 f/2.8 lens, this L-series lens has an entirely new optical design with three Aspherical elements and a Super UD-glass element. The combination provides superb contrast and sharpness, even at the widest settings. It's ideal for both film and digital SLRs, and features the same weather-resistant design, rear gel filter holder, and high-speed Ultrasonic Motor as the EF 16-35mm lens.
