The world's smallest, lightest ultra-wide-angle constant F4 APS-C power zoom lens.
Internal zoom and focus allows for the lens to maintain its length when focusing or zooming.
Expand your possibilities for visual expression with the power zoom system, making it easy to execute super-slow constant-speed zooms and perform other operations that are difficult with manual zoom.
Power zoom minimizes the camera shake that can occur when operating a zoom ring so that even solo shooters can produce smooth, stable movie sequences.
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 rates 4K or 8K movies, which this lens handles with ease.
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 the unwanted angle of view shifts during focusing for smooth, high-quality movie footage.
