The Sony FE 100-400mm f/4.5 GM OSS Lens is a premium super-telephoto zoom lens engineered for professional wildlife, birding, sports, aviation, and journalism photographers who demand uncompromising optical performance, fast autofocus, and reliable portability. Combining Sony’s flagship G Master image quality with a constant f/4.5 maximum aperture, advanced Optical SteadyShot stabilization, and internal zoom and focus designs, this versatile telephoto lens delivers exceptional reach and precision for capturing distant subjects with stunning clarity.
Designed as a true all-in-one super-telephoto solution, the FE 100-400mm f/4.5 GM OSS replaces multiple telephoto primes while maintaining outstanding sharpness, smooth bokeh, and professional handling. Its constant f/4.5 aperture provides brighter performance at the long end of the zoom range compared to traditional variable-aperture telephoto zooms, offering improved low-light capability and enhanced subject separation for dramatic wildlife portraits, field sports, and action photography.
At the heart of the lens is Sony’s renowned G Master optical design, featuring ED XA, XA, Super ED, and ED lens elements that minimize aberrations while maximizing sharpness, contrast, and color accuracy throughout the zoom range. Nano AR Coating II suppresses flare and ghosting for rich contrast and vibrant color reproduction even in difficult backlit situations, while the rounded 11-blade diaphragm produces beautifully smooth, natural background blur.
Built for speed and precision, the lens utilizes four XD linear motors for exceptionally fast, quiet, and responsive autofocus performance. Optimized for Sony’s latest high-speed mirrorless cameras, the FE 100-400mm f/4.5 GM OSS supports continuous shooting rates up to 120 fps and high-frame-rate video recording up to 240 fps. Sony’s advanced tracking algorithms improve autofocus speed and subject tracking accuracy, making this lens ideal for fast-moving wildlife, birds in flight, motorsports, and professional sports coverage.
The internal zoom and internal focusing design maintain the lens’s overall length during operation, preserving balance for easier handheld shooting and smoother performance on monopods, tripods, and gimbals. Focus breathing has been significantly reduced for professional video applications, and compatible Sony cameras can further enhance cinematic performance with Breathing Compensation support.
For handheld shooting at extreme focal lengths, Sony’s advanced Optical SteadyShot image stabilization system delivers sharp results with multiple stabilization modes optimized for standard shooting, panning, and moving subjects. A close focusing distance as short as 2.1 feet and up to 0.25x magnification also provide impressive near-macro versatility for capturing detailed close-up images of wildlife, nature, and sports equipment.
Despite its impressive reach and bright constant aperture, the lens remains highly portable thanks to a balanced internal design and durable hybrid metal-and-polycarbonate construction. Weather sealing throughout the lens protects against dust and moisture in harsh outdoor environments, while a fluorine-coated front element resists fingerprints, water, and dirt for easier cleaning in the field. Additional professional features include a de-clickable aperture ring for smooth video iris transitions, customizable function controls, programmable focus hold buttons, rear drop-in filter compatibility, and a removable rotating tripod collar.
The Sony FE 100-400mm f/4.5 GM OSS Lens is also fully compatible with Sony’s optional 1.4x and 2.0x teleconverters, extending its reach up to an incredible 800mm while retaining full autofocus and auto-exposure functionality. Whether photographing birds in flight, professional sports, wildlife safaris, outdoor adventures, or cinematic telephoto video, this G Master super-telephoto zoom delivers elite-level performance for Sony E-mount creators.
