Sony FE 85mm F1.4 GM
The Sony 85mm F1.4 GM features a new XA (extreme aspherical) element as well as three ED glass elements that work together to ensure that the in-focus areas are captured in extremely high resolution while the surrounding out-of-focus areas dissolve smoothly into a beautiful soft backdrop. It has a circular aperture with 11 blades – the most ever used in an Alpha lens – that ensures bokeh is smooth and visually appealing. Externally, the new model has Sony’s original Nano AR Coating, which is of particular importance in a portrait lens as it reduces flare and ghosting, even with backlit subjects or similarly challenging lighting conditions.
For accurate autofocusing, the FE 85mm F1.4 GM lens includes a ring drive SSM motor system that provides ample power and speed to drive the lens’ large, heavy focus group. It’s also equipped with two position sensors to support flawless focus control of the large, heavy lens elements.
This new professional portrait lens is dust and moisture resistant and also has an aperture ring with on/off switchable click stops that can be adjusted based on whether a user is shooting still images or movies. It also has an AF / MF switch and a focus hold button2.
