Sony has expanded its professional G Master lineup in the Philippines with the launch of the Sony FE 100-400mm F4.5 GM OSS, a super-telephoto zoom lens designed for wildlife, sports, and action photography. The lens introduces faster autofocus performance, a constant F4.5 aperture, and improved handling for field use.
The launch strengthens Sony’s position in the high-end mirrorless ecosystem, targeting creators who need long-range reach and fast subject tracking for both photography and video work.
G Master Optics Built for Long-Range Detail
At its core, the Sony FE 100-400mm F4.5 GM OSS focuses on maintaining sharpness and clarity across its full zoom range under Sony. The constant F4.5 aperture ensures consistent exposure while zooming, which is crucial for fast-moving subjects.
Key optical features include ED, Super ED, and XA lens elements for reduced chromatic and spherical aberration, Nano AR Coating II to minimize flare and ghosting, an 11-blade circular aperture for smoother background separation, and an internal zoom design for stable balance during shooting.
The lens also supports teleconverters, extending reach up to 800mm or 1,200mm (APS-C mode) for more demanding wildlife or distant subject capture.

Faster Autofocus for Sports and Wildlife Tracking
Sony equips the Sony FE 100-400mm F4.5 GM OSS with four XD Linear Motors, significantly improving autofocus performance compared to previous generations under Sony.
Performance upgrades include up to 3x faster autofocus speed versus the previous model, improved subject tracking accuracy for moving subjects, and compatibility with high-speed burst shooting on Alpha 9 series bodies.
These improvements position the lens for fast-paced environments such as sports events, wildlife photography, and press coverage where timing is critical.
Lightweight Build with Field-Oriented Design
Despite its reach, Sony designed the Sony FE 100-400mm F4.5 GM OSS for mobility, balancing optical performance with portability under Sony. It weighs approximately 1,840g and uses an internal zoom mechanism to maintain a stable center of gravity.
Other design features include dust and moisture resistance for outdoor use, a fluorine-coated front element for easier cleaning, four focus hold buttons for customizable control, and built-in Optical SteadyShot (OSS) for handheld shooting stability.

This makes the lens more practical for long field sessions where tripods are not always possible.
Compatibility and Use Cases
The Sony FE 100-400mm F4.5 GM OSS is designed for Sony’s full-frame E-mount Alpha system and is compatible with high-end bodies optimized for fast burst shooting and AI-based autofocus tracking.
It is positioned for wildlife photography (birds, animals, nature), sports coverage (indoor and outdoor events), photojournalism and documentary work, and long-range cinematic video capture. When paired with Sony’s teleconverters, the lens extends its flexibility further for extreme-distance shooting scenarios.
Buyers who pre-order within the promotional period will receive bundled accessories, including a choice of teleconverter.
Sony continues to expand its G Master ecosystem in the country, reinforcing its focus on professional creators who require high-resolution imaging, fast autofocus, and reliable field performance in a single system.
