Sony FE 100-400mm f/4.5 GM OSS Lens + Lens Bundle Bonus

G Master Optics with XA and Super ED Elements

The lens utilizes an advanced optical design featuring XA, ED XA, Super ED, and ED elements to achieve the high sharpness, smooth rendering, and minimized chromatic aberrations expected from Sony’s G Master lineup. Nano AR Coating II further suppresses flare and ghosting for strong contrast and accurate color reproduction when working in backlit or high-contrast environments. A rounded 11-blade diaphragm contributes to smooth, natural bokeh and pleasing subject separation.

High-Speed XD Linear Autofocus System

Four XD (extreme dynamic) linear motors deliver fast, responsive, and nearly silent autofocus performance suitable for professional wildlife and sports photography.

• Supports continuous shooting speeds up to 120 fps on compatible camera bodies.
• Improved subject tracking algorithms provide more accurate tracking of fast-moving and erratic subjects.
• Quiet autofocus performance is suitable for both still photography and video recording applications.

Internal Zoom Design for Stable Handling

Unlike extending super-telephoto zooms, the internal zoom mechanism maintains the overall lens length throughout the zoom range for improved balance and predictable handling. Combined with the internal focusing design, this helps maintain a consistent center of gravity during handheld shooting, tripod work, and gimbal-based video operation while also improving overall durability and weather resistance.

Optical SteadyShot and Reduced Focus Breathing

The built-in Optical SteadyShot stabilization system helps produce sharper handheld images at long focal lengths and includes dedicated modes for standard shooting, panning, and moving subjects. Focus breathing has also been significantly reduced optically, and the lens supports Sony’s Breathing Compensation function in select cameras for more stable framing transitions during video recording.

Close-Focus Capability and Floating Focus Design

The floating focus system maintains high image quality throughout the focusing range while enabling close focusing distances as short as 64 cm at the wide end. Combined with a maximum magnification of 0.25x, the lens is capable of capturing tightly framed detail shots and near-macro compositions while retaining excellent sharpness and contrast.

Hybrid Video Controls and De-Clickable Aperture

For hybrid creators and cinematographers, the lens includes a dedicated manual aperture ring that can be de-clicked for smooth and silent iris transitions during recording. The internal zoom mechanism also prevents physical extension during operation, making the lens easier to balance on stabilizers and support systems for professional video production workflows.

Teleconverter-Ready Super-Telephoto Reach

The lens is compatible with Sony’s optional FE 1.4x and 2.0x teleconverters while retaining autofocus and auto-exposure functionality. With teleconverters attached, the lens can achieve effective focal length ranges up to 140-560mm f/6.3 or 200-800mm f/9, extending its usefulness for wildlife, birding, and extreme telephoto shooting applications.

Weather-Sealed Professional Construction

Built for demanding outdoor environments, the lens features extensive dust- and moisture-resistant sealing throughout the barrel and mount area.

• Fluorine coating on the front element repels water, oil, and dust for easier cleaning.
• Removable rotating tripod collar improves balance and supports quick orientation changes.
• Four programmable focus hold buttons provide fast access to custom camera functions.
• Supports both 95mm front screw-in filters and 40.5mm rear drop-in filters.
