Product Information
The Sony FE 100-400mm f/5.6-8 OSS is a compact super-telephoto zoom for 35mm full-frame Alpha cameras with Sony E-mount. Its 100–400mm range brings distant wildlife, sports, trains, aircraft, and landscape details closer while keeping the lens at an approximate 654g.
Reach with a portable build
Two ED glass elements and two aspherical elements support clear rendering across the zoom range. A 9-blade circular aperture helps create soft background blur, and close-up capability reaches 0.41x maximum magnification with a 1.13m minimum focus distance at the wide end and 0.86m at the telephoto end.
Ready for handheld tracking
A linear motor provides fast, precise, quiet autofocus, while built-in optical image stabilization helps suppress camera shake during handheld shooting. The focus hold button, focus mode/range switching dial, and zoom lock switch put key controls within reach.
Outdoor-minded operation
The dust- and moisture-resistant design is intended to support changing outdoor conditions, though it is not guaranteed to be 100% dust- and moisture-resistant. The supplied lens hood helps prevent flare and ghosting. For additional reach, the separately sold Sony SEL20TC 2x teleconverter can extend coverage to 800mm, or 1200mm in APS-C mode.
