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

Canon RF 24-105mm f/4 L IS USM Lens
Premium L-Series Standard Zoom – Fully Functional / Good Condition (Moderate Internal Dust)
Prized for its ultimate versatility and professional-grade performance, the Canon RF 24-105mm f/4 L IS USM is the quintessential standard zoom designed for full-frame RF-mount mirrorless cameras. Covering a highly practical focal spectrum from wide-angle landscapes to short-telephoto portraits, this lens is characterized by its constant f/4 maximum aperture, which maintains consistent exposure across the entire zoom range.

As a member of Canon’s elite luxury L-series, it is robustly weather-sealed and packed with high-end telemetry, including a customizable Lens Control Ring, a rock-steady 5-stop Optical Image Stabilizer, and a cutting-edge Nano USM autofocus motor that delivers near-silent tracking optimized for both stills and cinema. This package includes both the front and rear lens caps.

Please note: This lens is in fully operational, overall Good cosmetic and structural condition. The internal optical path houses a moderate accumulation of fine dust particles from standard field use, which does not alter your day-to-day image quality.

Key Features & Professional Optical Systems
Constant f/4 Maximum Aperture: Maintains consistent light transmission throughout the entire zoom range, allowing you to alter your focal length without affecting your manual exposure or shutter speed settings.

5-Stop Optical Image Stabilization: Built-in mechanical image stabilization counteracts handheld camera shake by up to five shutter stops, enabling crisp, blur-free exposures when shooting run-and-gun video or handheld in low ambient light.

Advanced Nano USM Autofocus Drive: Combines a high-speed ring-type USM with a smooth, fluid STM mechanism to deliver lightning-fast, ultra-precise, and near-silent autofocus tracking that satisfies both high-speed photographers and solo filmmakers. Supports full-time manual focus override.

Configurable Lens Control Ring: Features Canon’s signature tactile control ring on the barrel, which can be custom-programmed to adjust ISO, aperture values, shutter speed, or exposure compensation directly on the lens.

Super Spectra Coatings: Individual optical glass elements feature specialized multi-layer coatings to significantly suppress internal reflections, ghosting, and lens flare, preserving deep contrast and color neutrality.

9-Blade Rounded Diaphragm: Built with a rounded nine-blade aperture array that produces a smooth, natural bokeh quality for beautifully rendered out-of-focus background highlights.

Weather-Resistant L-Series Chassis: Sealed aggressively against dust and environmental moisture to ensure reliable operation when deployed in inclement weather or trying outdoor environments.

Item Condition & Diagnostic Notes
Functional & Mechanical Performance: FULLY OPERATIONAL. This lens has been thoroughly tested and all systems perform flawlessly. The Nano USM focus motor actsuate instantly and tracks silently. The mechanical zoom and focus rings turn evenly and smoothly without any binding, the image stabilization engages perfectly, and all electronic communication with the camera body is completely stable.

Internal Dust Condition (Good): The internal optical path houses a moderate accumulation of dust particles. This standard buildup is common for extending zoom lenses that see regular field use. In rigorous diagnostic test shots, the dust does not degrade image resolution or frame contrast, and no dust spots manifest in final exposure files even when stopped down. The glass elements themselves are entirely free of scratches, fungus, haze, or separation.

Cosmetic Presentation: The lens exterior is in overall Good cosmetic condition. The matte-black outer housing shows standard light signs of regular handling, such as minor surface scuffs or slight rubbing on the control ridges, but is free of any severe impact damage or deep scratches.

Included Accessories: Includes the front lens cap and rear lens cap. (Please note: The original matching bayonet lens hood is not included).
