The lens comes equipped with a swift and responsive twin linear motor autofocus system and an optical image stabilization mechanism that compensates for up to five stops, substantially reducing the impact of camera shake on image clarity. With a robust, weather-resistant build and a front element coated with fluorine to repel moisture and debris, it promises reliable performance in adverse conditions.
