Canon EF 24-105mm f/4L IS II USM Lens

Canon EF 24-105mm f/4L IS II USM Lens
Professional Full-Frame Standard Zoom for Canon EF Mount – Constant f/4 Maximum Aperture, 4-Stop Optical Image Stabilizer (IS), Ring-Type Ultrasonic Motor (USM) with Full-Time Manual Override, Redeveloped L-Series Optics (4 Glass-Molded Aspherical Elements), Air Sphere Coating (ASC) & Front/Rear Fluorine Coatings, Weather-Resistant Construction, Rounded 10-Blade Diaphragm, Includes Front & Rear Caps plus Dedicated Petal Lens Hood (Excellent Condition)

The Canon EF 24-105mm f/4L IS II USM is a versatile, professional standard zoom lens engineered for full-frame Canon EF-mount DSLRs (also compatible with APS-C bodies providing a 38.4-168mm equivalent range, and EOS R mirrorless cameras via EF-EOS R adapters). Serving as an all-around workhorse for event coverage, travel photography, studio portraiture, documentary stills, and video production, it spans from wide-angle landscapes to short-telephoto portrait compression while maintaining a constant f/4 maximum aperture across the entire zoom range.

The redeveloped optical formula features 17 elements in 12 groups, incorporating four Glass-Molded (GMo) aspherical elements—including one large-diameter double-sided GMo element—to minimize distortion, spherical aberrations, and peripheral vignetting for improved edge-to-edge sharpness. Canon’s Air Sphere Coating (ASC) suppresses flare and ghosting in harsh, backlit scenarios, while protective fluorine coatings on the front and rear exposed glass repel water, oil, and fingerprints. Handheld shooting is supported by an optical Image Stabilizer (IS) providing up to 4 stops of shake correction. Autofocus is powered by a high-torque ring-type Ultrasonic Motor (USM) paired with an internal focusing (IF) design, optimized algorithms, and a high-speed CPU for fast, quiet, and precise focusing with full-time manual override. Built to Canon L-series standards, the lens features comprehensive dust- and moisture-resistant weather sealing, a zoom lock switch, a 77mm filter thread, and a rounded 10-blade circular diaphragm for smooth background bokeh.

CONDITION DIAGNOSTICS & PHYSICAL NOTES

Included Components: Supplied with the Canon EF 24-105mm f/4L IS II USM lens, Canon 77mm front snap-on lens cap, Canon EF-mount rear bayonet dust cap, and authentic Canon dedicated petal lens hood (EW-83M).

Exterior & Physical Status: EXCELLENT CONDITION. The matte black composite and metal barrel, ribbed rubber zoom and focus rings, distance scale window, AF/MF and IS switches, zoom lock switch, hood bayonet mount, and metal EF bayonet flange show minimal signs of light handling.

Optical & Electronic Status: FULLY FUNCTIONAL. Optical glass elements are clean and free of scratches, haze, or fungus; the zoom mechanism extends smoothly; the ring-type USM autofocus locks swiftly, silently, and accurately; the 4-stop Image Stabilizer engages properly; the rounded 10-blade diaphragm actuates reliably across all apertures.

KEY FEATURES & PERFORMANCE HIGHLIGHTS

24-105mm Versatile Focal Span: Spans wide-angle vistas, everyday street perspectives, and flattering telephoto portrait lengths in a single lens.

Constant f/4 Maximum Aperture: Maintains uniform exposure and depth of field throughout the entire zoom range.

4-Stop Optical Image Stabilization (IS): Counteracts camera shake by up to 4 stops for sharp handheld shooting in low light and at slower shutter speeds.

4 Glass-Molded (GMo) Aspherical Elements: Minimizes optical distortion and spherical aberrations for crisp, corner-to-corner resolving power.

Air Sphere Coating (ASC) & Fluorine Layers: ASC suppresses internal reflections and flare; fluorine coatings protect outer glass against smudges and moisture.

Ring-Type USM Autofocus: High-speed CPU and optimized algorithms deliver fast, whisper-quiet AF performance with seamless full-time manual focus override.

Internal Focusing (IF) Design: Maintains a fixed front barrel orientation during focusing, facilitating the use of circular polarizers and 77mm filters.

Rounded 10-Blade Diaphragm: Yields smooth, rounded out-of-focus highlights and soft background separation.

Robust L-Series Weather Sealing: Gasket-sealed construction protects internal mechanics and electronics against dust and moisture in challenging outdoor conditions.
