The lens features a focus mode switch as well as a zoom lock to prevent it from extending under its own weight. The zoom lock can also be released via zoom operation, ensuring the lock won't make you miss a shot.
A water- and oil-repellent coating on the front lens element makes it possible to shoot in harsh outdoor environments, while the dust- and splash-resistant construction keeps the internal elements protected.

Advanced simulation technology has been used to optimize backlight resistance, minimizing potential lens flare and ghosting.

Separate focusing elements work together to maintain focus throughout the entire zoom range.
