Covering an expansive 100–400mm focal range, this telephoto zoom lens is designed for wildlife, sports, aviation, and distant action photography. Compatible with full-frame EOS DSLRs and APS-C cameras, it provides an effective reach up to 160–640mm equivalent, allowing photographers to frame faraway subjects tightly while retaining flexibility to zoom out for environmental context.
Advanced optical construction uses one fluorite element, one Super UD element, and four aspherical elements to minimize chromatic and spherical aberrations. A floating element system maintains consistent sharpness, contrast, and color accuracy throughout both the zoom and focus ranges, ensuring dependable image quality at every focal length and working distance.
Built-in optical image stabilization reduces the appearance of camera shake by up to two shutter speed stops, improving handheld shooting and low-light performance. A ring-type Ultrasonic Motor delivers fast, precise, and quiet autofocus with full-time manual override, while a dedicated panning stabilization mode supports continuous tracking of moving subjects.
Professional L-series construction includes a removable rotating tripod collar for balanced support, adjustable zoom tension with position lock for stable handling, and compatibility with optional 1.4x and 2x teleconverters. An eight-blade diaphragm produces smooth background blur, helping isolate subjects with pleasing depth and separation.
