Sony FE 300mm F/2.8 GM OSS Lens (SEL300F28GM)

A Lightweight Super-Telephoto Lens
The Sony FE 300mm f/2.8 GM OSS is a full-frame super-telephoto prime lens made for Sony E-mount cameras. It is designed for sports, wildlife, and action photography, where fast autofocus, long reach, and bright optics matter most. It is also notably lightweight for a 300mm f/2.8 lens, which makes it easier to carry and handle in the field.

Built for Speed and Precision
This lens uses a constant f/2.8 aperture, giving you strong subject separation and solid low-light performance. Sony’s dual XD linear motors provide fast, quiet autofocus, while Optical SteadyShot helps reduce camera shake during handheld shooting. That combination makes it well suited for fast-moving subjects.

Designed for Professional Use
The lens body is built with dust- and moisture-resistant construction for more reliable outdoor use. It includes an internal focusing design, a rotating tripod collar, and a drop-in filter slot for added practicality. Sony also uses Nano AR Coating II and fluorine coating to help reduce flare and keep the front element cleaner.

Optical Performance
The optical design includes 20 elements in 16 groups, with three Super ED elements and one ED element to control chromatic aberration. The 11-blade diaphragm helps create smooth, attractive background blur. This makes the lens strong not only for action, but also for portraits and subject isolation.
