Get the ultimate in high quality, wide-angle shots with the Canon EF 17-35mm F/2.8 L USM Lens. Bringing together the high precision of a molded glass aspherical element with two additional replica aspherical lenses, this lens achieves an extended zoom range, but overcomes the common aberrations often found during that process. The ultra-low dispersion of the glass element also works to minimize chromatic aberration of magnification to obliterate color bleed while retaining high image contrast and great resolution. The minimum focusing distance of .28cm through the entire range of focal lengths makes it fantastic for close-up work without compromising on quality. Add your favorite compatible camera body and you have one incredible piece of equipment at the ready to meet your highest needs.
