RF 24-105mm F4L IS USM

The Canon RF 24-105mm F4L IS USM is a professional-grade standard zoom designed for full-frame mirrorless photographers who need a versatile single-lens solution. Featuring weather-sealed construction and a broad 24-105mm focal range, it is built to handle the demands of outdoor and travel photography where changing lenses is impractical.

Performance is anchored by a constant f/4 maximum aperture, ensuring consistent exposure throughout the zoom range. The optical design utilizes 18 elements in 14 groups, including one UD and one aspherical element, while the Nano USM motor provides fast, quiet internal focusing. For handheld work, the lens features optical image stabilization rated for 5 stops of shake reduction, complemented by a dedicated control ring for tactile adjustments of camera settings.

Despite its utility, the f/4 aperture may not satisfy users who require the extreme background separation or low-light intake of an f/2.8 lens. Weighing 700g with a length of 107mm, it is a significant addition to a camera bag and may feel bulky for those seeking a lightweight kit. Furthermore, with a minimum focus distance of 45cm and a 0.24x maximum magnification, it lacks the specialized close-up performance needed for dedicated macro photography.
