As part of Sony's
premium G Master series, this lens is designed to achieve notably high
resolution and sharpness through the correction of a wide variety of spherical
and chromatic aberrations. Additionally, these lenses feature robust and
intuitive-to-handle physical designs to benefit both photography and cine
wide-angle prime is designed for full-frame Sony E-mount mirrorless cameras;
however, it can also be used on APS-C models where it provides a 21mm
equivalent focal length.
Notably fast f/1.8
maximum aperture benefits working in difficult lighting conditions and also
affords increased control over depth of field.
Two XA (extreme
aspherical) elements, and one standard aspherical element, are incorporated
into the optical design, which features superior surface precision for
effective control over astigmatism, field curvature, coma, distortion and other
spherical aberrations for a high degree of sharpness and accurate rendering.
One Super ED element
and two extra-low dispersion elements are featured in the lens design and help
to reduce chromatic aberrations and color fringing for improved clarity and
Nano AR Coating II has
been applied to reduce surface reflections, flare, and ghosting for increased
contrast and color rendering in strong lighting conditions. This updated
coating is better suited for larger, curved elements and is especially adept at
minimizing internal reflections.
An XD Linear Motor
system uses two separate motors, along with an internal focusing design, to
provide quick, quiet, and precise autofocus and tracking performance. This
design also contributes to more natural, intuitive Linear Response manual focus
control and an AF/MF switch is located on the lens barrel for quick focus mode

A focus hold button is
present on the lens barrel for intuitive tactile control and rapid access to
select programmable settings.
Physical aperture ring
can be de-clicked for smooth, silent aperture switching to benefit video
applications. The ring also incorporates a locking "A" position for
use in automated exposure modes.

petal-shaped lens hood helps to block stray light from causing lens flare and
also affords some physical protection to the front element.
