Sony Unveils the FE 100-400mm F4.5 GM OSS G Master™

Dubai, United Arab Emirates, May 15, 2026 — Sony 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. 

“Our creators want super-telephoto reach with G Master optical quality in a body light enough to shoot handheld all day. The FE 100-400mm F4.5 GM OSS delivers constant F4.5 aperture, dramatically faster autofocus, and a build that keeps up with the user’s instincts, whether tracking a bird in flight or working the sideline at a championship match,” said Jason Rego, Head of Digital Imaging, Sony Middle East and Africa. 

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 center 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 teleconverters3 for focal lengths up to 800 mm or 1,200 mm in APS-C mode4

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 fps5 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 center 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 compensation6, correcting angle-of-view shifts during focus adjustments in video recording 
• Four focus hold buttons7 and a dedicated function ring for intuitive, personalized operation in the field 
• Dust and moisture resistant design8 with fluorine front-element coating maintains reliable performance in challenging conditions

The FE 100-400mm F4.5 GM OSS will be available from July 2026
