Two XA elements achieve outstanding corner-to-corner resolution all the way up to the lens’s maximum F1.8 aperture. One Super ED and two ED glass elements thoroughly suppress color bleeding for outstanding image-wide sharpness. Sony’s Nano AR Coating II effectively minimises 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 realise extraordinary overall performance in a remarkably compact lens that weighs just 460 grams.

Advanced optics with a high-curvature XA front element minimise 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.

With precise XA elements, a 9-blade circular aperture mechanism, and optimally managed aberration, this unique ultra-wide lens is capable of creating exquisite background bokeh without undesirable onion-ring artifacts. Minimum focus distance is just 0.25m.

Two XD Linear Motors provide the thrust efficiency required to accurately position the lens’s focus groups, achieving fast, precise, quiet AF performance. Quiet, low-vibration AF is an unprecedented advantage for shooting movies with ultra-wide angles.

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 used in outdoor conditions.
