Reach distant subjects with confidence – thanks to the 100–400mm zoom range
A versatile 100–400mm focal range covers medium to super-telephoto perspectives without the need to change lenses. Zoom increments allow framing flexibility when subjects move unpredictably.
Capture birds in tree crowns or players at the far side of the pitch without swapping lenses. Faster workflow and fewer missed moments when tracking action.
Sharp, clear images at long focal lengths – with UD glass and optical image stabiliser
Ultra-Low Dispersion (UD) glass elements reduce chromatic aberration while a 5.5-stop optical image stabiliser compensates for camera shake. The combination preserves edge-to-edge detail, especially at telephoto settings.
Maintain high image quality even when shooting handheld at long reach. Cleaner files and less reliance on very high ISO settings.
Portable for fieldwork – with compact form and STM autofocus
Measured at around 164.7mm in length and weighing approximately 635g, the lens is engineered for manageable carry. STM autofocus motors drive fast, quiet and smooth focusing suitable for stills and video.
Easier to spend long hours following subjects without fatigue, while silent focusing reduces distraction and aids discreet shooting. Practical for travel and extended sessions outdoors.
