Compact, expressive 10-20 mm F4 power zoom

At just 178 grams this is the world’s smallest, lightest ultra-wide-angle 10-20 mm (35mm full-frame equivalent: 15-30 mm) power zoom lens for APS-C cameras , offering class-leading mobility as well as outstanding handling and control. A constant F4 maximum aperture allows the use of practical shutter speeds even when shooting in low light.

Dynamic ultra-wide-angle images

A 10 mm focal length (35mm full-frame equivalent: 15 mm) at the wide end of the zoom range provides extremely wide angles of view. This versatile lens can deliver impressive, dynamic images utilizing unique perspectives that effectively separate the subject from the background, and emphasize distance or speed in movies.

Excellent G Lens resolution

Three aspherical elements effectively suppress field curvature and astigmatism that can be problematic in wide angle lenses, while an ED (Extra-low Dispersion) aspherical element contributes to outstanding image-wide resolution throughout the 10 to 20 mm zoom range (35mm full-frame equivalent: 15 to 30 mm).

Outstanding close-up performance

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 0.2 meters with a maximum magnification of 0.14x, while minimum manual focus distance is 0.13 ~ 0.17 meters with a maximum magnification of 0.18x.

Lever-controlled power zoom 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 imagery.

Internal zoom and focus for great handling

Internal zoom and focus mechanisms ensure that the lens does not change in length when zooming or focusing. Shifts in the lens’s center of gravity are minimal, making it a great choice for stable vlogging and gimbal-mounted movie shooting.

Designed for sophisticated movie imagery

Advanced lens technology reduces focus breathing as well as focus and axial shift when zooming so that high quality images can be easily captured. This lens also supports the breathing compensation function provided in compatible α series bodies, further reducing unwanted angle of view shifts during focusing for smooth, high-quality movie footage.

Linear Response MF

Linear Response MF ensures that the focus ring responds directly and linearly to subtle control when focusing manually. Focus ring rotation translates directly to a corresponding change in focus, so control feels immediate and precise enough for rack focus effects when shooting movies.

Extraordinary AF for stills and movies　

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 4K or 8K movies, and this lens handles it with ease.
