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.

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

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 20mm zoom range (35mm full-frame equivalent: 15 to 30mm).

A new electronic power zoom system instantly converts zoom ring control to actual zoom operation so that the creator’s intent is faithfully captured. Precise changes in angle of view can be easily produced and reproduced as needed, providing extra capability for visual expression.

This remarkably compact lens includes an ED (Extra-low Dispersion) aspherical element and two ED glass elements that subdue chromatic aberration throughout the image area, achieving natural colour and high contrast without colour bleeding.

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.

In addition to the zoom controls built into the lens, zoom can be controlled from assignable buttons and controls on compatible camera bodies, accessory grips, or remote commanders for convenient, versatile operation in a variety of situations.

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 minimises camera shake that can occur when operating a zoom ring so that even solo shooters can produce smooth, stable imagery.

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

At just 178 grams this is the world’s smallest, lightest ultra-wide-angle 10-20mm (35mm full-frame equivalent: 15-30mm) 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.

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.

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.

A focus mode switch right on the lens makes it possible to switch between autofocus and manual focus on the fly, to adapt to changing shooting conditions.

A customisable focus hold button is provided for easy access and convenient control in just about any shooting situation. Other functions can be assigned to the focus hold button from the body menus.

Within a remarkably compact design this lens features a focusing ring, zoom ring, and zoom lever that maximise control and versatility for movies as well as stills. The adjacent focus and zoom rings are stepped so they can be easily differentiated and operated by feel while viewing the monitor. [1] Focusing ring [2] Zoom ring [3] Zoom lever.
