Just 55 mm long and weighing a mere 178 grams (2-1/4 inches, 6.3 oz.). Thanks to internal zoom and focus, the lens does not change in length when zooming or focusing, providing a stable center of gravity that is ideal for vlogging and gimbal-mounted shooting.

A 10 mm (35mm full-frame equivalent: 15 mm) focal length at the wide end of the zoom range provides extremely wide angles of view that can easily cover sweeping scenes or reveal more in small spaces.

Three aspherical elements suppress field curvature and astigmatism while an ED (Extra-low Dispersion) aspherical element subdues chromatic aberration for high image-wide resolution throughout the 10 to 20 mm zoom range (35mm full-frame equivalent: 15 to 30 mm).

A new electronic power zoom system instantly converts zoom ring rotation to actual zoom operation. There’s also a zoom lever that makes it easy to execute super-slow constant-speed zooms that are difficult with manual zoom. Zoom can also be controlled remotely from the optional GP-VPT2BT grip.

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.

Advanced lens technology reduces focus breathing as well as focus and axial shift when zooming. This lens also supports the breathing compensation function provided in compatible Alpha series bodies, further reducing unwanted angle-of-view shifts during focusing for smooth movie footage.
