The Canon EF 24-105mm f/4L IS II USM is a professional-grade standard zoom lens delivering exceptional versatility from wide-angle to mid-telephoto coverage. This Mark II version features a redesigned optical formula with 17 elements in 12 groups, including four glass-moulded aspherical elements that significantly reduce distortion and spherical aberrations for superior sharpness across the entire zoom range. The constant f/4 maximum aperture maintains consistent exposure throughout the focal length, whilst advanced Air Sphere Coating suppresses flare and ghosting in challenging lighting conditions. A four-stop Image Stabilizer system minimises camera shake for sharper handheld shooting, and the ring-type USM autofocus delivers quick, quiet, and accurate focusing with full-time manual override. Weather-sealed construction with fluorine-coated elements ensures durability and reliable performance in demanding environmental conditions. Ideal for photographers and videographers seeking a flexible, reliable walk-around lens for landscapes, portraits, video work, and professional assignments.
