Canon EF-S 10-22mm f/3.5-4.5 USM Lens

Canon EF-S 10-22mm f/3.5-4.5 USM Lens
Ultra-Wide Angle Zoom Lens for Canon EF-S Mount – 16-35.2mm Equivalent Focal Range, Fast Ring-Type USM Autofocus, 1 Super-UD & 3 Aspherical Elements, Super Spectra Multi-Coating, Internal Focusing Design, Includes Front & Rear Lens Caps (Good Condition / Front Element Scratch)

The Canon EF-S 10-22mm f/3.5-4.5 USM is an ultra-wide zoom lens engineered specifically for APS-C-format Canon EF-S-mount digital SLR cameras, delivering an expansive 16-35.2mm full-frame equivalent focal length range. Designed to provide dynamic wide-angle coverage in a compact, portable form factor, this lens excels in architectural photography, tight interior documentation, sweeping landscapes, travel, and creative environmental portraiture.

The advanced optical formula utilizes 13 elements in 10 groups, incorporating one Super-Ultra-Low Dispersion (Super-UD) glass element and three precision aspherical elements to effectively curb chromatic aberrations, reduce color fringing, and control spherical distortion across the entire focal range. Individual elements are treated with Canon’s Super Spectra Coating to eliminate flare, ghosting, and internal reflections, preserving rich contrast and natural color accuracy in backlit conditions. Autofocus is driven by a high-torque ring-type Ultrasonic Motor (USM) paired with an Internal Focusing (IF) mechanism, delivering swift, near-silent AF acquisition and seamless full-time manual focus override without altering the physical length of the lens during operation.

CONDITION DIAGNOSTICS & PHYSICAL NOTES

Included Components: ULTRA-WIDE ZOOM LENS UNIT. Supplied with the Canon EF-S 10-22mm f/3.5-4.5 USM lens, front lens cap, and rear EF-S bayonet cap.

Exterior & Physical Status: GOOD CONDITION. The composite lens barrel, ribbed zoom ring, manual focus ring, distance scale window, and EF-S bayonet mount exhibit standard cosmetic surface marks and signs of handling consistent with regular field use.

Optical & Mechanical Status: FULLY FUNCTIONAL WITH NOTED GLASS BLEMISH. The internal optical assembly contains light dust particles typical for zoom lenses, alongside one scratch located slightly off-center on the front optical element (tested and verified not to affect captured image rendering or exposure). The ring-type USM autofocus motor tracks swiftly and quietly; the internal focusing mechanism is smooth; the zoom mechanism and electronic aperture control operate properly.

KEY FEATURES & PERFORMANCE HIGHLIGHTS

16-35.2mm Equivalent Ultra-Wide Perspective: Captures sweeping landscape vistas, dynamic architectural exteriors, and tight indoor spaces with ease.

Super-UD & Triple Aspherical Optics: Integrates 1 Super-UD element and 3 aspherical elements to ensure edge-to-edge sharpness while suppressing distortion and chromatic aberrations.

Ring-Type Ultrasonic Motor (USM): Provides rapid, precise, and whisper-quiet autofocus tracking with seamless full-time manual focus override.

Internal Focusing (IF) Architecture: Maintains a fixed lens barrel length and non-rotating front filter thread during operation for balanced handling and easy polarizer use.

Super Spectra Multi-Coating: Minimizes ghosting and flare while preserving rich contrast and accurate color rendition in bright or harsh lighting.

Rounded 6-Blade Diaphragm: Softens out-of-focus background areas for natural, pleasing depth-of-field separation.
