This compact and lightweight ultra-wide-angle power zoom lens combines outstanding mobility and image quality to realize opportunities that only wide field of view and power zoom can provide. Offering dynamic perspectives¹, corner-to-corner sharpness, naturally rendered bokeh, fast, precise AF and optical design refined for movies, this lens is ideal for use with E-mount APS-C and Super35 cameras.

The world's smallest, lightest ultra-wide-angle constant F4 APS-C power zoom lens¹
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.

Dynamic perspectives and outstanding G Lens resolution throughout the 10-20mm zoom range
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)

Power zoom with variable speed lever, responsive operation and control
A new electronic power zoom system instantly converts zoom ring control to change in focal length, so the creator’s intent is faithfully captured. Precise changes in angle of view can be easily achieved, providing extra capability for visual expression. A zoom lever with continuously variable zoom speed makes it easy to execute super-slow constant-speed zooms and perform other operations that are difficult with manual zoom. Power zoom minimizes camera shake that can occur when operating a zoom ring so that even solo shooters can produce smooth, stable movie sequences.

Fast, precise, quiet AF and excellent response
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

Reduced focus breathign and shift while zooming for refined movie imagery
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 footage².

Consistent balance for easy handling with internal focus and zoom structures
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.

Control zoom remotely with compatible cameras, accessories or smart devices
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 situations³.

Naturally rendered bokeh and excellent close-up performance (7.9” AF)
The use of aspherical elements in an advanced optical design also ensures excellent close-up performance throughout the lens’s zoom range. Minimum autofocus distance is just 7.9” (0.2 m) with a maximum magnification of 0.14x, while minimum manual focus distance 5.1 - 6.7” (0.13 – 0.17 m) with a maximum magnification of 0.18x.

Linear Response MF for precise, repeatable manual focus control
Linear Response MF ensures that the focus ring responds directly and linearly to subtle control when focusing manually. It also provides precise repeatability. Focus ring rotation translates directly to a corresponding change in focus, so control feels immediate and precise when shooting stills or movies.

Dust and moisture resistant design
An updated dust and moisture resistant design⁴ provides extra reliability for outdoor use in challenging conditions. Silicon seals around buttons and switches and a rubber gasket around the lens mount greatly reduce the likelihood of dust and moisture incursion.
