With a constant F4.5 aperture, autofocus up to 3x faster, and outstanding mobility, the new lens gives wildlife, birding, sports, and photojournalism the tool to expand their creative possibilities.
Covering a 100-400 mm focal range with a constant F4.5 aperture, the lens delivers, Sony claims, “the exceptional resolution and bokeh that define the G Master series, high-precision autofocus (AF) up to approximately 3x faster than the FE 100-400mm F4.5-5.6 GM OSS. The AF speed claim is valid for when the lens is mounted on the Alpha 9 III. Based on Sony test conditions.
Weighing approximately 65 oz. (1,840 g) with an internal zoom structure, its stable weight balance offers highly mobile shooting capabilities, Sony adds. 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 Yoshioka Naoto, Head of Marketing, Imaging, Products and Solutions, Sony Europe.
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 teleconverters (compatible with 1.4x Teleconverter (SEL14TC) and 2x Teleconverter (SEL20TC) for focal lengths up to 800 mm or 1,200 mm in APS-C mode, with 2x Teleconverter (SEL20TC) attached.
Four custom-optimized XD (extreme dynamic) Linear Motors, a floating focus mechanism, and the latest AF algorithms deliver AF speeds up to 3x faster with approximately 50 % improved subject tracking.
Fully compatible with Alpha 9 III continuous shooting at up to 120 fps with AF/AE tracking. Based on Sony test conditions. Continuous shooting speed may decrease depending on shooting conditions. When focus mode is set to AF-C, continuous shooting speed varies depending on the lens attached. Check the lens compatibility information support page for details.
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 compensation, correcting angle-of-view shifts during focus adjustments in video recording. Refer to support information for compatible cameras. When this function is set to [On], angle of view and image quality may change slightly. Depending on the lens, compensation may not be fully effective even when this function is set to [On].
Four focus hold buttons and a dedicated function ring for intuitive, personalized operation in the field. Important note: assignable functions vary depending on the camera used. Refer to support information for compatible cameras for details.
Dust and moisture resistant design with fluorine front-element coating maintains reliable performance in challenging conditions. Note: The lens is designed with dust and moisture resistance in mind but is not completely sealed against dust or water droplets.
