OVERVIEW
See more of the world with a compact wide-angle zoom
This compact full-frame F2.8 wide-angle zoom lens is an excellent match for α-series cameras, with advanced technology ensuring that camera performance is fully realized from ultra-wide 16 mm to wide 25 mm focal lengths. Outstanding G LensTM resolution and bokeh are available throughout the focal range. Precision AF means fast, sharp focus for wide-angle stills, as well as movies.
Sharp and detailed at all focal lengths
Three ED (Extra low Dispersion) glass elements and four aspherical elements that include one ED Aspherical glass element deliver high resolution from 16 mm to 25 mm. Flare, ghosting, and color bleeding are subdued for clarity, while F2.8 and 11 aperture blades create stunning G Lens bokeh. Max. magnification is 0.2x (AF)/0.23x (MF) with a minimum focus distance of 0.18 m (0.59ft) (AF)/0.17 m (0.56ft) (MF) at the wide end for stunning close-ups.
AF that brings out the best in high-performance bodies
Two specially optimized linear motors and a precision control system acquire focus on any subject with remarkable speed and accuracy. Tracking performance is also excellent and fully capable of keeping up even with Sony’s advanced model α9 III camera at up to 120 fps. Precise, quiet focus is smoothly acquired and maintained even when shooting high frame rate 4K 120p or FHD 240p movies.
A compact F2.8 wide zoom that is ready to go anywhere
With four aspherical elements that include one ED Aspherical glass element, and a large F2.8 maximum aperture in a high-performance optical design, this innovative lens is no more than 74.8 mm in diameter by 91.4 mm in length (3 x 3-5/8 inch). The use of engineering plastics for some components enhances durability while reducing weight to just 409 grams (14.5 oz.), making this a low-stress F2.8 choice for long shooting sessions or low-light situations.
Constant F2.8 in a mobile zoom is great for movies
Two specially optimized linear motors and a precision control system acquire focus on any subject with remarkable speed and accuracy. Minimal zoom extension and centre of gravity shift make gimbal or drone mounting easy too. And combined with in-body Active Mode stabilization it can deliver stable handheld footage at wide angles while walking around. It also supports in-body breathing compensation4 and metadata recording.
Comprehensive control in a compact lens
Focus, zoom, and aperture rings provide comprehensive control. The aperture ring features an aperture click ON/OFF switch. A customizable focus hold button and AF/MF switch are also provided. Linear Response MF ensures immediate, intuitive manual focus control. A dust and moisture resistant design maximizes reliability in challenging outdoor conditions, and the front element features a fluorine coating. Filter diameter is 67 mm.
