   The highly durable design is built to perform in even the most challenging environments. It delivers a dust and water-resistant construction with seals around the mount, switches, zoom ring and more.

   Fluorine Coating

   To help maintain a clean lens, the front and rear lens surfaces feature a smudge-resistant fluorine coating that helps repel water and oil and can easily be cleaned with a dry cloth.

The lens features a fast and near-silent AF system so you don’t disturb your subject, and includes an inner focusing ring USM system that works in combination with a high-speed CPU and AF algorithms to help deliver precise, fast performance. It also offers full-time manual focus.
