Professional build quality with dust, splash and freeze-resistant design
The optimized lens configuration has 17 elements in 13 groups, including 1 ASPH, 4 ED and 1 UHR lenses to minimize aberrations and ensure superb resolution. This lens is designed to keep shooting in the toughest conditions thanks to its dust- and splash-resistant construction and allowing you to shoot in temperatures as low as -10°C. The fluorine coating applied to the front lens prevents the sticking of oil-based dirt.
