Early bird Promotion - 15 May to 4 June
 
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
