Super-telephoto zoom with constant F4.5 aperture, autofocus up to 3x faster, , and outstanding mobility
(MALAYSIA, 13 May 2026) – Sony Electronics introduces the FE 100-400mm F4.5 GM OSS, the newest addition to its flagship G Master™ lens series for full-frame Alpha™ E-mount cameras. Covering a 100-400 mm focal range with a constant F4.5 aperture, the lens delivers the exceptional resolution and bokeh that define the G Master series, high-precision autofocus (AF) up to approximately 3x faster1,2 than the FE 100-400mm F4.5-5.6 GM OSS. Weighing approximately 65 oz. (1,840 g) with an internal zoom structure, its stable weight balance offers highly mobile shooting capabilities. The FE 100-400mm F4.5 GM OSS gives wildlife, birding, sports, and photojournalism creators the speed, reach, and image quality to capture decisive moments in any environment, expanding their creative possibilities.
Uncompromising G Master Optics
- Resolves fine detail across the full 100-400 mm zoom range, even wide open at F4.5
- Optical design featuring newly developed ED XA (Extra-low Dispersion extreme aspherical), XA (extreme aspherical), two Super ED (extra-low Dispersion), and three ED glass elements, effectively controlling multiple aberrations including chromatic and spherical aberration to achieve exceptional resolution from centre to edge across the entire zoom range
- Nano AR Coating II reduces ghosting and flare for high-contrast results in backlit conditions
- 11-blade circular aperture with precision spherical aberration control produces the signature G Master bokeh
- Constant F4.5 maximum aperture eliminates exposure shifts while zooming
- Compatible with optional teleconverters for focal lengths up to 800 mm or 1,200 mm in APS-C mode
Autofocus That Keeps Pace with the Action
- Four custom-optimized XD (extreme dynamic) Linear Motors, a floating focus mechanism, and the latest AF algorithms deliver AF speeds up to 3x faster1,2 with approximately 50 % improved subject tracking2
- Fully compatible with Alpha 9 III continuous shooting at up to 120 fps with AF/AE tracking
Lightweight Build, Exceptional Mobility
-
Combining the latest optical design, mechanical engineering with lightweight yet robust magnesium alloy barrel components, and high-efficiency, high-thrust XD Linear Motors, the lens achieves a lightweight and robust body at approximately 65 oz. (1,840 g)
- Inner-zoom design maintains constant length and stable centre of gravity throughout the zoom range for precise framing adjustments without shifting balance
Professional-Grade Control and Reliability
- Built-in stabilization supports Active Mode and coordinates internal stabilization control on compatible bodies
- Supports the camera body’s breathing compensation, correcting angle-of-view shifts during focus adjustments in video recording
- Four focus hold buttons and a dedicated function ring for intuitive, personalized operation in the field
- Dust and moisture resistant design with fluorine front-element coating maintains reliable performance in challenging conditions
Availability
The FE 100-400mm F4.5 GM OSS will be available from May 2026 with the SRP of RM17,999.
