Combining professional-grade performance with a lightweight, compact design, this versatile long-telephoto zoom is an excellent choice for both dedicated field photography and casual shooting. Its focal range excels at capturing fast-moving subjects such as sports, wildlife, and motorsport, yet its sub-1.2kg weight also makes it perfect for telephoto landscapes and pet portraits. With a maximum magnification ratio of 1:4.1, it even handles macro-style close-ups with ease. The 100-400mm delivers exceptional sharpness across the entire zoom range, aided by one FLD and four SLD elements that effectively suppress optical aberrations.
Light enough for handheld use, the lens features Sigma''s intelligent two-mode Optical Stabilizer, which minimizes camera shake at slower shutter speeds. For tripod users, a removable rubberized barrel ring allows the attachment of an optional tripod collar. Additional features—such as a focus limiter, customizable AFL button, lockable zoom ring, dust- and splash-resistant mount, and custom modes—make this lens adaptable to a wide range of shooting conditions.
The exterior barrel is made from Thermally Stable Composite (TSC), a durable polymer with thermal expansion properties similar to aluminum. This ensures consistent performance across changing temperatures while offering strength, reduced weight, and a sleek, premium finish.
With Dual Action Zoom, users can adjust focal length either by rotating the rubberized zoom ring for precision or by push-pulling the barrel for quick changes. The zoom can also be locked at multiple positions. A removable rear rubber cover allows for tripod collar installation, providing extra stability when mounted.
The brass lens mount is surrounded by a protective rubber seal to guard against dust and moisture. Control options include an AF/MF switch, a customizable AFL button (camera-dependent), and a focus limiter for faster, more accurate focusing—particularly useful when foreground distractions might otherwise interfere. The Optical Stabilizer offers up to four stops of compensation, with one mode for general shooting and another optimized for panning—ideal for tracking fast-moving subjects like birds or vehicles.
Autofocus is powered by a stepping motor, designed for both speed and smoothness in stills and video. The lighter focus lens group ensures quick, precise AF performance fully compatible with the latest camera systems.
Despite weighing only 1,135g, the 100-400mm F5-6.3 DG DN | C delivers outstanding resolution across the entire frame—even on high-megapixel sensors. Its advanced optical formula consists of 22 elements in 16 groups, including four SLD and one FLD element, ensuring crisp detail and supporting in-camera corrections for chromatic aberration, distortion, flare, and vignetting. Multi-layer coatings further suppress flare and ghosting in backlit conditions, producing high-contrast images with rich color and deep blacks.
Thanks to its portability and remarkable image quality, the 100-400mm has become a favourite among landscape photographers, who use it to isolate small details within a scene and compress perspective for striking compositions.
