Featuring 16 elements in 13 groups, this zoom's optics have been optimized to provide greater resolution, clarity, and bokeh quality.

Faster focusing performance, improved close-up shooting, and enhanced control are all benefits of the redesigned focusing system.

Just as camera design has grown to appeal to both photo and video shooters, this lens has also been updated with attributes that specifically appeal to the needs of video shooters.

Bringing a bright, f/2.8 maximum aperture to a compact and lightweight optic, the lens is primed for a broad spectrum of use cases and remains a weather-sealed, durable lens for use in trying working conditions.

• Fit with a manual aperture ring, tactile exposure control is possible. This ring can be de-clicked for smooth and silent iris pulls, or it can be locked in the 'A' position for camera-based aperture switching.
• One programmable focus hold button and a focus mode switch for intuitive focus control.
• Dust- and moisture-resistant design for use when working in inclement weather conditions. The front lens element has a fluorine coating that repels water, oil, and other contaminants and makes the lens easier to clean.
• Included lens hood has been redesigned to complement the lens's sleek design by reducing both its diameter and length.
