• A new era of standard zoom performance

No-compromises design and technology in a new constant F2.8 zoom lens that can fully utilize the performance potential of current and future high-resolution camera bodies.

• Unprecedented resolution and detail

An XA (extreme aspherical) element with superlative surface precision works with ED elements  for extraordinary resolution that can capture breathtaking texture and detail.

• Bright, fast F2.8 at any focal length

Keep exposure settings constant throughout the zoom range to maintain low-light capability or action-stopping shutter speeds with consistently spectacular image quality.

• Precise focus at blazing speed

Direct Drive SSM (DDSSM) minimizes spurious motion while refined algorithms enhance AF operation speed. Smooth and quiet for movies as well as stills.

• Professional lens control features

A focus mode switch, focus hold button, and zoom lock switch provide professional control for a wide range of shooting situations.
