Sony Announces FE 300mm F2.8 GM OSS: World’s Lightest Large-Aperture Telephoto Prime

Published: November 7, 2023


SAN DIEGO – November 7, 2023 – Sony Electronics is pleased to announce the release of the world’s lightest 300mm telephoto prime lens G Master, a fullframe Alpha E-mount lens with a maximum aperture of F2.8.

The anticipated Sony FE 300mm F2.8 G Master OSS lens has the high depiction performance and high-speed, high-precision AF (autofocus) which are the hallmark of G Master. The lightweight design of approximately 1470g (excluding tripod mount) and excellent weight balance allow the user to capture sharp, dynamic and decisive moments such as those of fast-moving sports or agile animals with handheld shooting. Paired with the Alpha 9 III full-frame camera that also launched today, high-speed continuous shooting with AF/AE tracking up to 120 frames per second is possible. Even subjects with complex and diversified movements can be tracked with high precision. It is an ideal match for lightweight camera bodies by reducing the load on the user, minimizing fatigue during long handheld shooting sessions. It is also compatible with an optional teleconverter, allowing the user to shoot in the telephoto range of up to 600mm (equivalent to 900mm when using with an APS-C camera).

“Ever since our announcement of the development of this lens in January of this year, we have received an overwhelming number of positive reactions from photographers around the world who are looking forward to its release,” said Yang Cheng, Vice President, Imaging Solutions, Sony Electronics. “By adding this 300mm lens to the already available E-mount 400mm and 600mm super-telephoto prime lensesv ,it supports a wide range of needs and shooting environments for professional and advanced amateur photographers.”

G Master Telephoto Lens that Captures Decisive Moments with High Resolution and Beautiful Bokeh

Incorporating Sony’s cutting-edge technology, the G Master’s high-resolution performance and beautiful bokeh makes the subject stand out clearly and capture decisive moments such as sports, news reports, events, and wildlife photography. An innovative optical design that includes three Super ED (Extra-low Dispersion) glass elements and one ED glass element, effectively placed to suppress chromatic aberration and achieve high resolution and contrast across the entire frame. Outstanding resolution and contrast are maintained right out to the image edges, which also allows for more flexible cropping and editing.

The gorgeous, creamy bokeh is a hallmark of the G Master design and ideally complements the lens’s 300 mm focal length and F2.8 maximum aperture, allowing the use of narrow depth of field to make subjects stand out from the background. Each lens is individually calibrated during manufacture to optimize bokeh quality and has an 11-blade circular aperture mechanism that contributes to smooth rounded bokeh. ​


High-Performance AF that Captures Dynamic Moments and High-Speed Continuous Shooting with AE/AF Tracking up to 120 Frames per Second

The combination of two latest XD (extreme dynamic) Linear Motors and control algorithms provide high-speed, high-precision, and low-vibration AF performance. When combined with the newly announced Alpha 9 III full-frame camera, high-speed continuous shooting with AF/AE tracking of up to 120 frames per second is possible. This allows dynamic subjects to be captured without missing a moment’s opportunity, even when shooting scenes in which the subject moves quickly, such as sports or animals, or scenes in which the subject moves erratically, such as at competitive events. The high AF performance is demonstrated even when the separately sold teleconverter is attached.

Exceptional Mobility and Comfortable Operability that Support Professionals in the Field

Extensive weight reduction measures make FE 300mm F2.8 GM OSS the lightest in its classi, at approximately 1470g (excluding tripod mount) and has been designed with consideration to weight balance. The internal lens barrel uses durable magnesium alloy to achieve both high robustness and light weight. The weight is not concentrated at the front of the lens barrel, making it highly stable and allows for agile and accurate panning while shooting. In addition, MODE3, which provides enhanced viewfinder stability and optimizes the image stabilization algorithm, allows you to accurately capture dynamic scenes.

When used with the Sony Alpha 9 III, the user can assign “preset focus” to the function ring that allows for an instant recall of focus to any pre-determined positionvii. Furthermore, the lens features comfortable operability that supports professional shooting, including focus hold buttons placed in four locations that can be assigned to the favorite functions from the camera body making it ideal for any professional.

The FE 300mm F2.8 G Master OSS has a dust and moisture resistant design along with fluorine coating to help prevent dirt and fingerprints to keep up with the needs of professional photographers.
