Canon RF-S 10-18mm f/4.5-6.3 IS STM Ultra-Wide Zoom Lens (Canon RF, Black)
Ultra-Compact APS-C Wide-Angle Zoom – Dynamic 10-18mm Focal Range (16-29mm Full-Frame 35mm Equivalent), Optical Image Stabilizer (IS) with Up to 4.0 Stops Shake Correction (Up to 6.0 Stops with Coordinated Control IS), Lead Screw-Type STM Stepping Motor for Smooth, Near-Silent Autofocus & Full-Time Manual Override, Optical Design Featuring Two Ultra-Low Dispersion (UD) Elements & One Aspherical Element, Super Spectra Coating for Flare & Ghosting Suppression, Dual-Function Focus/Control Ring, Rounded 7-Blade Diaphragm for Smooth Background Blur, Retractable Ultra-Lightweight 5.3 oz Form Factor, 49mm Front Filter Thread, Native Canon RF Mount for APS-C & Full-Frame EOS R Cameras in 1.6x Crop Mode (Good Condition)

The Canon RF-S 10-18mm f/4.5-6.3 IS STM is an agile, ultra-compact wide-angle zoom lens engineered specifically for Canon APS-C format EOS R-series mirrorless cameras (delivering an expansive 16-29mm full-frame 35mm equivalent focal perspective). Designed as an essential wide optic for vloggers, landscape photographers, interior documentarians, and travel creators, this lens provides dramatic perspective exaggeration and expansive field-of-view coverage in a pocketable chassis. Measuring just 1.77 inches in length when retracted and weighing a featherweight 5.3 ounces, it pairs seamlessly with compact EOS R bodies to allow effortless handheld shooting and gimbal balancing without fatigue.

Optical performance is anchored by a modern 12-element in 10-group optical configuration incorporating two Ultra-Low Dispersion (UD) glass elements to suppress chromatic aberrations and color fringing, alongside one precision aspherical element to correct spherical aberrations and distortion across the zoom range. Canon’s Super Spectra multi-coating is applied to internal elements to curb lens flare, internal reflections, and ghosting, maintaining rich micro-contrast and accurate color balance in backlit conditions. Handheld stability is bolstered by an integrated Optical Image Stabilizer (IS) providing up to 4.0 stops of shake compensation on its own, which expands up to 6.0 stops of Coordinated Control IS when paired with EOS R bodies equipped with In-Body Image Stabilization (IBIS). Driven by a lead screw-type STM stepping motor, the lens delivers fast, whisper-quiet autofocus suitable for both stills and smooth Movie Servo AF video tracking. Featuring a dual-purpose focus/control ring, a rounded 7-blade circular diaphragm, and direct RF mount compatibility across both APS-C and full-frame EOS R cameras (via automatic 1.6x crop), this ultra-wide zoom provides versatile performance in solid, field-tested condition.

CONDITION DIAGNOSTICS & PHYSICAL NOTES

Included Components: ESSENTIAL ULTRA-WIDE ZOOM OUTFIT. Supplied with the Canon RF-S 10-18mm f/4.5-6.3 IS STM lens, front 49mm snap-on lens cap (E-49), and genuine Canon rear RF lens dust cap. (Lens hood EW-53B, camera bodies, 49mm screw-in filters, and storage pouches sold separately unless pictured).

Exterior & Barrel Status: GOOD CONDITION. The matte black composite barrel, ribbed rubber zoom control ring, forward knurled focus/control ring, and composite RF bayonet mount show normal cosmetic signs of standard field handling. Light surface scuffs, shallow rub marks along outer barrel contours, and minor finish shine on contact points are visible upon close inspection. All white painted focal length indicators, Canon badging, and mount alignment markings remain clean, intact, and fully legible.

Optical Status: GOOD CONDITION. Both front and rear external optical glass surfaces are clean and free of prominent scratches, chips, haze, fungus, or element separation. The internal optical assembly is clean and clear with only trace, negligible dust specks typical of standard zoom use; thorough bench testing confirms these specks do not appear in captured photos or video, having zero impact on resolving power, edge contrast, or color fidelity across working apertures. Factory Super Spectra coatings remain intact.

Mechanical & Electronic Diagnostics: FULLY FUNCTIONAL. The internal STM stepping motor acquires focus swiftly, accurately, and quietly; full-time manual focus override responds smoothly; the manual retractable zoom mechanism extends and retracts smoothly across the 10-18mm range with uniform factory resistance; the dual-function focus/control ring operates properly; the optical Image Stabilizer engages cleanly with no jump or drift; the rounded 7-blade diaphragm stops down crisply without sticking or oil residue; gold-plated RF electronic contacts communicate Exif metadata and in-camera lens corrections reliably with zero camera error codes.
