AF 150-500mm f/5-6.3 APO EX DG HSM OS for EOS

Ultra-telephoto zoom lens with optical stabiliser.

This super telephoto is the lens of choice for professionals who need maximum quality. The quality of the image is ensured by the apochromatic design, achieved by the use of Special Low Dispersion glass elements. In addition to that, Super Multi-Layer lens coating ensures that as much light as possible reaches the sensor, minimising ghosting and flare.
The handling of the lens is excellent, thanks to the use of a Hyper Sonic Motor for quick and decisive autofocus with full-time manual override, while the Optical Stabiliser lets you use shutter speeds up to four stops slower than would otherwise be possible with hand-held shooting.
