Sony FE 100-400mm F5.6-8 OSS Super-Telephoto Zoom Lens SEL100400

Product Description:

The Sony FE 100-400mm F5.6-8 OSS (SEL100400) is a compact, lightweight super-telephoto zoom lens for Sony E-mount full-frame cameras that captures distant moments and expressions with outstanding clarity — weighing just 654 grams (23.1 ounces) with a maximum diameter of 78.2mm and a length of only 164.5mm. Designed for enthusiasts and professionals who shoot wildlife, birds, sports, portraits, and video, the SEL100400 fills the frame with distant subjects at focal lengths that were previously available only in much larger, heavier, and more expensive lenses — making super-telephoto photography genuinely portable and accessible.

The optical design features 15 elements in 10 groups, incorporating two ED (Extra-low Dispersion) glass elements that effectively minimize chromatic aberration and color bleeding, plus two aspherical elements that correct distortion and spherical aberration for sharp, clear rendering of subjects from near to distant. Multi-coating across all elements reduces flare and ghosting for high-contrast images in challenging backlit conditions. A nine-blade circular aperture produces smooth, natural bokeh that beautifully isolates subjects from cluttered backgrounds — a critical quality for wildlife portraiture and sports photography where clean background separation defines the impact of the image.

Close-up capability is surprisingly impressive for a super-telephoto zoom. A minimum focusing distance of just 0.86 meters (2.83 feet) at the telephoto end with a maximum magnification of 0.41× allows you to capture stunning close-ups of flowers, insects, and small wildlife details from a comfortable working distance — tele-macro performance that dramatically extends what you can do with a single lens beyond traditional long-range shooting.

Dual linear motors power fast, precise, and quiet autofocus that easily locks onto and tracks active subjects — from birds in flight to sprinting athletes to unpredictable children. The near-silent AF operation makes the lens ideal for video recording where motor noise would be picked up by the microphone. When paired with the Sony α9 III body, the lens supports burst shooting at up to 120 frames per second with full AF performance — a combination that makes capturing split-second decisive moments dramatically more reliable.

Optical SteadyShot image stabilization built into the lens compensates for the camera shake that is amplified at super-telephoto focal lengths, enabling handheld shooting at slower shutter speeds and maintaining a stable viewfinder image for easier subject tracking. On compatible Sony bodies, the lens's optical stabilization works in coordination with the body's in-body stabilization for even greater shake compensation.

Optional Sony teleconverters extend the lens's reach far beyond 400mm. The SEL14TC 1.4× teleconverter provides a 140-560mm range (210-840mm on APS-C), while the SEL20TC 2× teleconverter delivers 200-800mm (300-1200mm on APS-C) — extraordinary reach that brings even the most distant subjects into frame-filling range.

Physical controls are comprehensive and intuitive. A focus hold button on the barrel provides one-touch focus lock for recomposing and can be reassigned to other telephoto-support functions through the camera menus. A combined focus mode and focus range limiter switch (AF FULL / AF ∞-3m / MF) simplifies operation by putting mode selection and focus limiting in one control — reducing the time spent navigating menus in the field. A zoom lock switch prevents unwanted lens extension when the lens is aimed downward. Dust- and moisture-resistant construction with sealing at critical joints and seams ensures reliable operation in morning fog, rain, and dusty environments. 67mm filter thread. Made in Vietnam.
