Sony FE 400mm f/4.5 GM OSS Lens (Sony E)

Sony FE 400mm f/4.5 GM OSS Lens (Sony E) Overview

The Sony FE 400mm f/4.5 GM OSS is a remarkably lightweight super-telephoto prime lens designed for sports, wildlife, and action photography. Combining 400mm reach with G Master optical quality, fast autofocus, and Optical SteadyShot stabilisation, it delivers professional performance in a compact, handheld-friendly design.

Redefining Super-Telephoto Portability

• Lightweight Design: Weighs just 2.2 lb and measures only 9.5" long for easy handheld shooting.
• f/4.5 Maximum Aperture: Balances strong light-gathering performance with a shorter, lighter lens design.
• Balanced Handling: A single front element shifts the centre of gravity closer to the camera body for improved stability.
• Compact Alternative: Weighs 4.2 lb less and is 4.6" shorter than the FE 400mm f/2.8 GM OSS.

High-Speed AF & Optical SteadyShot

• XD Linear Motors: Two extreme dynamic linear motors provide fast, quiet, and responsive autofocus.
• High-Speed Compatibility: Supports continuous still and video shooting speeds up to 120 fps.
• Internal Focusing: Maintains the lens length during focusing for faster response and improved handling.
• Manual Focus Override: Enables full-time manual focus control.
• Focus Controls: Includes a focus range limiter and four focus hold buttons for greater autofocus control.
• Optical SteadyShot: Three stabilization modes support standard shooting, panning, and moving subjects.

G Master Optical Performance

• Advanced Optics: Super ED and ED glass elements reduce chromatic aberration and maintain high sharpness across the frame.
• Nano AR Coating II: Minimizes flare and ghosting for rich contrast and accurate colour in challenging light.
• 11-Blade Diaphragm: Produces smooth, rounded bokeh and natural subject separation.

Professional Handling & Build

• Removable Tripod Foot: Can be removed to create a slimmer, more comfortable handheld setup.
• Customisable Function Ring: Can be assigned to selected camera and exposure settings.
• Intuitive Controls: Frequently used switches and buttons are positioned for quick access while shooting.
• Weather-Resistant Construction: Rubber gaskets and a sealed lens mount help protect against dust and moisture.
• Fluorine-Coated Front Element: Repels water, oil, and contaminants for easier cleaning.
• 95mm Filter Thread: Supports standard screw-in filters.
• Hybrid Construction: Uses metal and plastic components to balance durability and portability.

Teleconverter Compatibility

• Compatible Teleconverters: Supports separately available Sony FE 1.4x and 2.0x teleconverters with autofocus and auto-exposure retained.
• With 1.4x Teleconverter: 560mm f/6.3 effective focal length and aperture.
• With 2.0x Teleconverter: 800mm f/8 effective focal length and aperture.
