This large-aperture ultra-wide-angle prime lens offers G Master quality in an innovative design that is incredibly compact. Advanced technology achieves breathtaking resolution plus exquisite bokeh even at maximum F1.8 aperture. Add fast, precise AF and extraordinary mobility, and you have a lens that can capture fresh views of everyday scenes.
Two XA (extreme aspherical) elements in a design that meets stringent G Master standards achieve outstanding corner-to-corner resolution all the way up to the lens's maximum F1.8 aperture. One Super ED (Extra-low Dispersion) and two ED glass elements thoroughly suppress color bleeding for outstanding image-wide sharpness and clarity, while Sony's Nano AR Coating II effectively minimizes flare and ghosting.
Precision aspherical elements including two ultra-precise XA elements in an innovative G Master optical design work with two of Sony's state-of-the-art XD Linear Motors to realize extraordinary overall performance in a remarkably compact lens that weighs just 16 ounces. This is one ultra-wide large-aperture lens you carry around anywhere, reshaping the world with creative new perspectives.
Adding to the versatility provided by its large aperture and ultra-wide angle of view, advanced optics with a high-curvature XA front element minimize sagittal flare when shooting starry skies and other night scenes. The large F1.8 maximum aperture allows low-light shooting without having to use extremely slow shutter speeds, while compact dimensions let you shoot anywhere with ease.
With precise XA elements, a nine-blade circular aperture mechanism, and optimally managed aberration, this unique ultra-wide lens is capable of creating exquisite background bokeh without unwanted onion-ring artifacts. Minimum focus distance is just 0.82 ft, so you can move right in to combine dynamic close-ups with beautiful bokeh in expansive backgrounds.
Two XD (extreme dynamic) Linear Motors provide the thrust efficiency required to accurately position the lens's focus groups, achieving fast, precise, quiet AF performance that maximizes the speed potential of E-mount bodies. Quiet, low-vibration AF is an unprecedented advantage for shooting movies with ultra-wide angles, while mobility and fast response give creators the freedom to work effectively with any subject.
In addition to a fluorine coating on the front element that repels water, oil, and other contaminants, the rear element is also fluorine-coated to keep that surface clean when changing the rear filter. A dust and moisture resistant design maximizes reliability when using this large-aperture ultra-wide-angle lens in challenging outdoor conditions.
