The Sony FE 24-105mm F4 G OSS is a constant maximum aperture full-frame (FE) zoom lens for the Sony E-mount, announced by Sony on October 25, 2017.

[1] Given its unusually high 1:3 (0.32x) image reproduction ratio, the 24-105mm lens can be considered a pseudo-macro lens.

Though designed for Sony's full frame E-mount cameras, the lens can be used on Sony's APS-C E-mount camera bodies, with an equivalent full-frame field-of-view of 36–157.5mm.

The lens showcases a matte-black weather resistant plastic exterior with a rubber focus and zoom ring.

There is also a programmable external focus-hold button and an Autofocus-Manual focus switch.
