Sony FE 100-400mm F4.5 GM OSS Full-frame Telephoto Zoom Lens with F...
The Sony FE 100-400mm F4.5 GM OSS Lens is a super-telephoto zoom lens designed for photographers and videographers who need reach, speed, and reliable control in demanding shooting conditions. It is built for wildlife, sports, birds, and documentary work, offering consistent performance across its zoom range.
Super-telephoto zoom range with constant aperture
This lens covers a 100–400mm focal range with a constant F4.5 aperture, allowing consistent exposure while zooming. It is designed for capturing distant subjects such as wildlife and sports action while maintaining exposure stability and flexibility in changing environments.
G Master optical performance
The lens uses advanced XA, Super ED, and ED elements to control optical aberrations and maintain image quality throughout the zoom range. This results in high resolution and clarity, along with smooth background rendering that supports strong subject separation.
Fast and reliable autofocus tracking
Powered by XD Linear Motors and advanced focusing algorithms, the autofocus system is designed to track fast-moving subjects with accuracy. It supports continuous shooting performance and maintains focus reliability during high-speed action scenarios.
Lightweight inner-zoom design
The inner-zoom construction and magnesium alloy materials help reduce overall weight and improve handling balance. This design allows more stable operation during extended shooting sessions while minimizing fatigue and maintaining consistent balance when zooming.
Optical stabilization and customizable control
Built-in Optical SteadyShot works together with camera stabilization to reduce shake during handheld shooting. The lens also includes customizable controls that allow users to adjust focus functions and shooting behavior for both photography and video use.
Durable build for field use
The lens features a dust and moisture-resistant design along with a fluorine-coated front element. This helps protect against environmental elements and makes the lens easier to clean, supporting reliable use in outdoor and challenging conditions.
