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

Canon EF-S 10-22mm f/3.5-4.5 USM Ultra-Wide Zoom Lens
High-Performance APS-C Ultra-Wide Zoom for Canon EF-S Mount – 16-35.2mm Equivalent Focal Range, 1 Super-UD & 3 Aspherical Elements, Ring-Type USM Autofocus with Internal Focusing, Super Spectra Coating, Non-Rotating Front 77mm Thread, Includes Front & Rear Lens Caps (Good Condition / Minor Internal Dust)

The Canon EF-S 10-22mm f/3.5-4.5 USM is an ultra-wide-angle 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. Renowned for its optical rendering and dynamic perspective, this lens is an essential tool for landscape photographers, architectural documentarians, real estate shooters, and travel creators seeking to capture dramatic wide fields of view with pronounced depth and edge-to-edge clarity.

The sophisticated optical formula consists of 13 elements in 10 groups, incorporating one Super-Ultra-Low Dispersion (Super-UD) element and three precision aspherical elements. This advanced arrangement effectively curbs chromatic aberrations, color fringing, spherical distortion, and field curvature across the entire zoom range. Individual elements feature Canon’s Super Spectra Coating to suppress flare, ghosting, and internal reflections for rich contrast and color fidelity in harsh daylight. Autofocus is powered by a high-speed, ring-type Ultrasonic Motor (USM) paired with an internal focusing (IF) architecture, delivering rapid, whisper-quiet focus acquisition and full-time manual focus override while keeping the physical length of the lens completely constant during operation. Its non-rotating front element easily accommodates 77mm circular polarizers and specialized filter setups, while a rounded 6-blade diaphragm ensures natural background defocus.

CONDITION DIAGNOSTICS & PHYSICAL NOTES

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

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

Optical & Mechanical Status: FULLY FUNCTIONAL WITH NOTED OPTICAL DUST. The internal optical elements contain light dust particles typical of pre-owned wide-angle zooms (tested and confirmed not to affect image sharpness, contrast, or everyday exposure). The ring-type USM autofocus motor tracks swiftly and quietly; the internal zoom and focus mechanisms rotate smoothly; the electronic aperture diaphragm stops down accurately across all f-stops on compatible Canon EOS APS-C camera bodies.

KEY FEATURES & PERFORMANCE HIGHLIGHTS

16-35.2mm Equivalent Ultra-Wide Perspective: Captures vast landscapes, dramatic interiors, and expansive architectural spaces with natural geometry on APS-C bodies.

Super-UD & Triple Aspherical Optics: Integrates 1 Super-UD element and 3 aspherical elements to eliminate optical aberrations and deliver corner-to-corner sharpness.

Super Spectra Multi-Coating: Minimizes lens flare and ghosting while maintaining neutral color rendition and strong image contrast in direct sunlight.

Ring-Type USM & Internal Focusing: Delivers fast, virtually silent autofocus tracking with seamless full-time manual focus override; internal focus maintains a fixed lens length.

Non-Rotating 77mm Front Thread: Front barrel does not rotate during focusing, simplifying the use of circular polarizers and ND filter systems.

Compact & Lightweight Profile: Weighs just 13.6 oz (385 g), making it a portable, travel-friendly ultra-wide solution for handheld photography.

Native Canon EF-S Mount Compatibility: Seamlessly mounts to all Canon EOS APS-C digital SLR bodies (Rebel series, 60D, 70D, 80D, 90D, 7D series).
