Small & light
Just 2-1/4” long and weighing a mere 6.3 oz. (55mm, 178 g), this is the world’s smallest, lightest ultra-wide-angle power zoom lens1. Thanks to internal zoom and focus, the lens does not change in length when focusing or zooming, providing a stable center of gravity that is ideal for vlogging or gimbal-mounted shooting. The unique combination of outstanding mobility and versatile power zoom opens up creative opportunities not possible with other lenses.
Fast, precise, quiet autofocus
Two linear motors ensure fast, quiet, low vibration autofocus that can smoothly track subjects when shooting high frame rate movies and reliably follow fast-moving subjects when shooting stills continuously at high speed. Focus is especially critical when shooting rate 4K or 8K movies, which this lens handles with ease.
Outstanding G Lens resolution
Dynamic, ultra-wide perspectives with outstanding resolution across the frame are assured with three aspherical elements to suppress field curvature and astigmatism that can be problematic in wide angle lenses. Two ED (Extra-low Dispersion) elements and an ED aspherical element contributes to outstanding image-wide resolution throughout the 10-20 mm zoom range (35mm full-frame eq 15-30 mm)
Reduced focus breathing
Advanced lens technology reduces focus breathing as well as focus and axial shift when zooming so that high quality images and movies can be easily captured. This lens also supports the breathing compensation function provided by compatible alpha cameras, further reducing unwanted angle of view shifts during focusing for smooth, high-quality movie footage.
Although this compact wide-angle zoom lens weighs just 6.3 oz (178 g), it does not compromise functionality or performance. Its length remains constant while focusing and zooming for optimal balance and handling, which also makes it ideal for gimbal or even aircraft-mounted movie shooting or with the use of a matte box.
Remote zoom control
In addition to the zoom controls built into the lens, zoom can be operated without having to touch the camera or lens, with variable speeds and from assignable buttons and controls on compatible cameras, accessory grips or remote commanders for convenient, versatile operation in a variety of situations.
