Sigma Canon APO 100-300mm F4 EX DG HSM Telephoto Lens

This telephoto Zoom Lens provides a large F4 Aperture at all focal lengths. The new multi layer lens coating and lens design reduce flare and ghosting while maintains minimal light-fall-off; superior peripheral brightness is ensured. New multi layer coating of this lens gives superb Color performance while cutting down flare and ghosting caused by reflections from the Digital image sensor. High Optical performance is demonstrated throughout the entire zoom range. Two SLD glass elements are used in the front lens group and two in the rear lens group for superior correction of several aberrations for superior image quality throughout the entire zoom range. An inner focusing system eliminates front lens rotation, making the lens particularly suitable for using the petal-type lens hood supplied and circular polarizing filters.
