Canon EF 17-40mm f4 L USM Lens and Hoya 77mm Circular Polariser Slim FilterThe Canon 17-40mm f4 USM is an affordable L-series ultra-wide-angle zoom lens that's ideal for both film and digital SLRs. This EF lens focuses as close as 0.28m. 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. The 17-40mm f4L also features a weather-resistant construction. he Hoya 77mm Circular Polariser Slim Filter allows you to significantly reduce reflections and glare from non-metallic surfaces. A camera angle of 30 degrees from the reflecting surface (glass, water, etc.) is ideal for maximum effect. This circular polariser also enables colours to become more saturated and appear clearer with better contrast. This effect is ideally suited to landscape photographers and is often used to increase the contrast and saturation in blue skies and white clouds. Its thin profile reduces vignetting when using wide angle lenses, but still allows a clip-on lens cap to be used. Back to top
