91 Sony FE 85mm f1.4 GM Lens

The Sony FE 85mm f/1.4 GM is a flagship portrait lens from Sony’s G Master series, engineered to deliver exceptional resolution and stunning background separation. Designed for full-frame Sony E-mount cameras, this lens combines a classic 85mm portrait focal length with a fast f/1.4 aperture—making it ideal for professional portrait, wedding, and fashion photography.

Its advanced optical design incorporates an XA (extreme aspherical) element along with ED glass to achieve outstanding sharpness, contrast, and minimal aberrations. The result is crisp subject detail paired with beautifully smooth, creamy bokeh—one of the defining characteristics of G Master lenses.

The bright f/1.4 aperture allows for excellent low-light performance and precise depth-of-field control, enabling photographers to isolate subjects with a soft, cinematic background. A rounded 11-blade aperture further enhances the quality of bokeh, delivering natural and pleasing out-of-focus highlights.

Equipped with a Direct Drive SSM (DDSSM) autofocus system, the lens provides precise and quiet focusing, suitable for both still photography and video applications. A manual aperture ring with click control, customizable focus hold button, and professional-grade build ensure intuitive handling and reliability in demanding shooting environments.

Built with durability in mind, the lens features dust- and moisture-resistant construction along with a fluorine-coated front element to protect against dust, oil, and water—making it ready for professional use in any condition.
