The Canon EF 24-105mm f/4L IS II USM is a flagship L-series standard zoom lens built for Canon EF-mount full-frame DSLRs, delivering a versatile wide-angle-to-short-telephoto range with a constant f/4 aperture. Its redesigned optical formula — featuring four aspherical elements, Air Sphere Coating, and Fluorine Coating — ensures razor-sharp, high-contrast images from edge to edge, whether you are shooting landscapes, portraits, or events.
Engineered for real-world shooting demands, this Canon zoom pairs a 4-stop Optical Image Stabilizer with a ring-type USM autofocus system for fast, silent, and precise focusing even in low light. The weather-sealed, dust-and-moisture-resistant body makes it a dependable all-in-one solution for professional photographers working in challenging outdoor conditions across Egypt and beyond.
Key features
- Versatile 24-105mm constant f/4 zoom: Covers wide-angle through short-telephoto in a single lens, maintaining consistent exposure throughout the entire zoom range — ideal for travel, weddings, and documentary work.
- 4-stop Optical Image Stabilizer: Significantly reduces camera shake blur during handheld shooting, enabling sharp results at slower shutter speeds in low-light environments.
- Four aspherical elements for edge-to-edge sharpness: Including one large-diameter double-sided glass-molded element, these optics minimize distortion and spherical aberrations across the full zoom range.
- Air Sphere + Fluorine Coatings for pristine image quality: Air Sphere Coating suppresses flare and ghosting in harsh backlit conditions, while Fluorine Coating on front and rear elements repels fingerprints, dust, and smudging.
- Ring-type USM with full-time manual focus override: Delivers quick, quiet, and accurate autofocus performance, allowing seamless manual intervention without switching AF modes.
- Weather-sealed L-series construction: Dust and moisture resistance, combined with the protective Fluorine Coating, keeps this lens performing reliably in demanding outdoor and environmental conditions.

Frequently asked questions
Is the Canon EF 24-105mm f/4L IS II USM compatible with APS-C Canon cameras?
Yes. While designed primarily for full-frame Canon EF-mount DSLRs, it is fully compatible with APS-C Canon bodies, where the crop factor provides an equivalent focal length range of approximately 38.4-168mm.
How effective is the Image Stabilizer on this lens?
The built-in Optical Image Stabilizer (IS) compensates for camera shake by up to four shutter speed stops, making it significantly easier to capture sharp handheld shots in low-light situations or at the longer end of the zoom range.
Does the Canon EF 24-105mm f/4L IS II USM offer weather protection?
Yes. As an L-series lens, it features a weather-resistant construction that guards against dust and moisture. Additionally, Fluorine coatings on the front and rear elements provide extra protection against fingerprints and smudging.
