Spanning an immensely versatile wide to telephoto range, the EF 28-300mm f/3.5-5.6L IS USM is a Canon L-series zoom well-suited for travel use or other situations where a one-lens kit is ideal. Using aspherical elements and ultra-low dispersion glass, both chromatic and spherical aberrations are well-corrected for notable sharpness and clarity throughout the zoom range. A Super Spectra coating also helps to minimize flare and ghosting for improved contrast and color accuracy, especially when working in backlit and bright conditions. Beyond the optical attributes, this 28-300mm is also characterized by its advanced three stop-effective Image Stabilizer system to minimize the appearance of camera shake. Also complementing handling is a sophisticated ring-type USM, which provides quick, quiet, and accurate autofocus performance along with full-time manual focus override. Additionally, this lens is weather-sealed for use in trying environmental conditions and it has a removable rotating tripod collar to benefit working atop a tripod or monopod. All-in-one 28-300mm zoom is designed for full-frame Canon EF-mount DSLRs, however can also be used with APS-C models where it provides a 44.8-320mm equivalent focal length.Three ultra-low dispersion glass elements noticeably reduce color fringing and chromatic aberrations for high clarity and color fidelity.Two aspherical elements minimize spherical aberrations and distortions for improved sharpness and accurate rendering.Super Spectra coating has been applied to individual elements to minimize ghosting and flare for greater contrast and color neutrality when working in strong lighting conditions.An Optical Image Stabilizer helps to minimize the appearance of camera shake by up to three shutter speed stops to better enable working in low-light conditions and with slower shutter speeds.A ring-type Ultrasonic Motor (USM), along with an internal focusing system, is employed to deliver fast, precise, and quiet autofocus performance as well as full-time manual focus override.Focus Limiter switch lets you constrain the focusing to two different ranges to suit different applications: 8.2'-infinity or 2.3'-infinity.Rounded eight-blade diaphragm contributes to a pleasing out of focus quality that benefits the use of shallow depth of field and selective focus techniques.As a member of the esteemed L-series, this lens is sealed against dust and moisture for working in inclement environmental conditions.Removable rotating tripod collar is included and benefits working with the lens atop a tripod or
