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

Canon EF 24-105mm f/4L IS 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, 1 Super UD & 3 Aspherical Elements, Super Spectra Coating, Dust- and Moisture-Resistant L-Series Construction, Includes Front Cap, Rear Cap & Dedicated Lens Hood (Good Condition / Minor Internal Dust)

The Canon EF 24-105mm f/4L IS USM is an industry-standard, professional workhorse zoom lens engineered for full-frame Canon EF-mount DSLRs and 35mm film SLRs (also fully compatible with APS-C bodies, where it provides a 38.4-168mm equivalent focal range). Spanning from an expansive 24mm wide angle to a versatile 105mm short telephoto perspective, this iconic L-series optic combines robust build quality with a constant f/4 maximum aperture, ensuring steady exposure parameters across the entire focal range. It remains a benchmark all-in-one solution for wedding documentation, commercial events, travel photography, photojournalism, and studio portraiture.

The advanced optical formula features 18 elements in 13 groups, incorporating one Super Ultra-Low Dispersion (Super UD) element and three precision aspherical elements to significantly suppress chromatic aberrations, color fringing, and spherical distortion for high edge-to-edge sharpness and accurate rendering. Canon’s Super Spectra Coating has been applied to reduce internal reflections, flare, and ghosting in high-contrast or backlit environments. Handheld shooting is enhanced by an integrated 4-stop Optical Image Stabilizer (IS) that counteracts camera shake in dim lighting and at slower shutter speeds. Autofocus is driven by a ring-type Ultrasonic Motor (USM) paired with an internal focusing (IF) mechanism and high-speed CPU, delivering rapid, whisper-quiet AF performance alongside full-time manual focus override. Built for rigorous professional field use, the lens incorporates weather-resistant rubber gaskets, an 8-blade circular diaphragm for pleasing background bokeh, and broad adaptability to modern mirrorless systems (such as Canon RF and Sony E) via electronic mount adapters.

CONDITION DIAGNOSTICS & PHYSICAL NOTES

Included Components: COMPLETE L-SERIES ZOOM LENS OUTFIT. Supplied with the Canon EF 24-105mm f/4L IS USM lens, Canon front lens cap, Canon EF rear bayonet dust cap, and dedicated Canon bayonet lens hood (EW-83H or compatible).

Exterior & Physical Status: GOOD CONDITION. The durable composite/metal L-series barrel, ribbed zoom and focus rings, AF/MF and IS selector switches, distance scale window, and metal EF bayonet mount show moderate, visible signs of handling, finish rubbing, and normal surface wear consistent with standard professional use.

Optical & Mechanical Status: FULLY FUNCTIONAL WITH NOTED LIGHT DUST. The front and rear optical glass surfaces are intact and free of scratches, haze, or fungus, with light internal dust particles present between the elements (thoroughly tested and verified to have zero impact on image sharpness, exposure, or contrast). The ring-type USM autofocus motor locks quickly and accurately; the 4-stop Image Stabilizer functions properly; zoom and manual focus rings rotate smoothly; the electronic 8-blade aperture stops down accurately across all f-stops on compatible Canon EOS camera bodies.

KEY FEATURES & PERFORMANCE HIGHLIGHTS

24-105mm Versatile Focal Span: Covers wide landscapes, documentary street scenes, environmental portraits, and tight telephoto framing in a single lens (38.4-168mm on APS-C).

Constant f/4 Maximum Aperture: Maintains consistent illumination, depth-of-field control, and exposure settings throughout the entire 4.4x zoom range.

4-Stop Optical Image Stabilizer (IS): Significantly reduces the appearance of camera shake for sharper handheld stills and smoother video in low ambient light.

Super UD & Aspherical Optical Elements: 1 Super UD and 3 aspherical elements work in tandem to eliminate chromatic aberrations, spherical distortion, and color fringing.

Super Spectra Multi-Coating: Minimizes lens flare and ghosting while enhancing overall contrast and color fidelity under strong lighting conditions.

High-Speed Ring-Type USM Autofocus: Internal focusing design and high-speed CPU deliver lightning-fast, nearly silent AF with seamless full-time manual focus override.

Professional L-Series Weather Sealing: Gasket-sealed construction protects vital internal optics and electronics against environmental dust and moisture.

Broad Compatibility & Adaptability: Mounts natively to all Canon EOS digital DSLRs and 35mm film SLRs, and adapts smoothly to Canon RF, Sony E, and Nikon Z mirrorless platforms via EF adapters.
