Product Overview
The Sony FE 100–400 mm f/4.5-5.6 GM OSS is a premium telephoto zoom lens designed for Sony full-frame E-mount mirrorless cameras. Built for professionals and advanced enthusiasts, it combines versatile reach, excellent sharpness, and high-quality optical stabilization—ideal for wildlife, sports, outdoor events, nature, and telephoto portrait photography.
Versatile Telephoto Zoom Range
With a focal length range of 100–400 mm, this lens delivers powerful reach suitable for distant subjects—wildlife, sports action, or landscape details—while also offering flexibility at the 100 mm end for tighter portraits or semi-wide telephoto shots. The wide zoom range makes it a go-to lens for outdoor and dynamic photography where changing lenses mid-shoot is impractical.
Premium Optical Construction for Sharp Results
As a member of Sony’s prestigious G Master (GM) line, the 100–400 mm lens features high-precision optics—including ED (Extra-low Dispersion) and Super ED glass elements—that reduce chromatic aberration, color fringing, and distortion even at long focal lengths. The lens delivers sharp detail, high contrast, and accurate color rendition from center to edges, preserving image quality throughout the zoom range.
Optical Stabilization for Handheld Shooting
Equipped with Optical SteadyShot (OSS), this lens helps counteract camera shake—particularly important at longer focal lengths or slower shutter speeds. OSS enables handheld shooting even in less-than-ideal lighting conditions or when a tripod is inconvenient, providing flexibility and reliability for photographers on the move.
Smooth, Fast Autofocus and Responsiveness
The lens uses dual linear autofocus motors for fast, precise, and near-silent focusing—beneficial for both still photography and video work. Whether you’re tracking a bird in flight or capturing unpredictable sports action, the autofocus system keeps up with subjects quickly and accurately. Additionally, the zoom and focus rings are well-damped and responsive for precise control.
Build Quality and Handling
The lens barrel is constructed with quality materials and includes dust and moisture resistance, making it suitable for outdoor use in challenging conditions. Despite its telephoto reach, the lens remains reasonably balanced and portable for wildlife or travel photographers. A removable and rotatable tripod collar provides flexibility when using a monopod or tripod, and the hood helps minimize flare and protect the front element.
Ideal for Wildlife, Sports & Outdoor Photography
Thanks to its focal range, optical quality, and stabilization, the 100–400 mm f/4.5–5.6 GM OSS lens excels when you need to bring distant subjects close—perfect for wildlife, birding, safari trips, sports events, and even distant landscape detail work. Its performance makes it a go-to telephoto zoom for professional and serious amateur photographers who value reach without sacrificing quality.
