(ASIA PACIFIC, 14 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[i] for focal lengths up to 800 mm or 1,200 mm in APS-C mode[ii]

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 faster^1,2 with approximately 50 % improved subject tracking²
• Fully compatible with Alpha 9 III continuous shooting at up to 120 fps[iii] 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[iv], correcting angle-of-view shifts during focus adjustments in video recording
• Four focus hold buttons[v] and a dedicated function ring for intuitive, personalized operation in the field
• Dust and moisture resistant design[vi] with fluorine front-element coating maintains reliable performance in challenging conditions
