Complementing the optical assets, this lens is also notable for its inclusion of an 11-blade circular diaphragm to produce smooth, soft-edged bokeh with selective focus imagery. For controlling focus, a linear SSM (Super Sonic wave Motor) is employed that is quick and quiet, and also lends more responsive control for manual focus operation. The lens also sports a dust- and moisture-sealed design to support shooting in inclement conditions and a dedicated focus hold button, AF/MF switch, and manual aperture ring lend further control while shooting.

As part of Sony's esteemed 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 applications.

A portrait-length prime designed for full-frame E-mount mirrorless cameras, this 85mm f/1.4 is also compatible with APS-C models where it will provide a 127.5mm equivalent focal length.

Fast f/1.4 maximum aperture benefits working in difficult lighting conditions and also offers a wealth of control over focus position when using shallow depth of field techniques.

One XA element is incorporated into the optical design, which features superior surface precision for effective control over astigmatism, field curvature, coma, and other spherical aberrations.

Three extra-low dispersion elements are featured in the lens design and help to reduce chromatic aberrations and color fringing for improved clarity and color neutrality.

A Nano AR Coating has been applied to reduce surface reflections, flare, and ghosting for increased contrast and color rendering in strong lighting conditions.

Rounded 11-blade diaphragm contributes to a pleasing bokeh quality when employing selective focus techniques.

A linear SSM system and internal focus mechanism provides quick, quiet, and precise autofocus performance and also contributes to more natural, intuitive manual focus control.

Dust- and moisture-sealed design better permits working in inclement conditions and rubberized control rings benefit handling in colder temperatures.

Manual aperture ring can be de-clicked for smooth, silent aperture switching to benefit video applications.
