Canon EF-S 18-55mm f/4-5.6 IS STM Lens

Canon EF-S 18-55mm f/4-5.6 IS STM Lens
Sleek, Compact Standard Zoom with Image Stabilization – Good Condition with Minor Optical Defect
The Canon EF-S 18-55mm f/4-5.6 IS STM is a compact, ultra-portable standard zoom lens engineered specifically for APS-C-format Canon DSLRs. Covering a highly adaptable 28.8–88mm equivalent focal length range, this lens spans from a wide-angle perspective for landscapes to a short telephoto view for portraiture, making it an excellent walk-around choice for daily documentation. This updated variant features a significantly slimmer form factor than previous kit lenses, backed by an Optical Image Stabilizer providing up to four stops of shake correction and a near-silent STM stepping motor optimized for video. Please note: This lens is in good structural condition and includes front and rear caps, but exhibits a small amount of light internal fungus.

Key Features & Engineering
Sleek, Compact Standard Zoom: Delivers a versatile 28.8–88mm equivalent focal length range in a low-profile chassis, offering a highly practical zoom range for daily travel, snapshots, and vlogging.

4-Stop Optical Image Stabilizer: Features an integrated Optical Image Stabilizer that counteracts handheld camera tremors by up to four shutter speed stops. This system allows for significantly sharper results when shooting handheld in low-light environments or with slower shutter speeds.

Lead Screw-Type STM Autofocus Engine: Driven by a smooth, near-silent stepping motor (STM) paired with a high-speed CPU and advanced AF algorithms for quick, precise focus acquisition. The quiet operation is highly optimized for video tracking, and full-time manual focus override allows for instant adjustment without switching modes.

Aspherical Optical Element: Incorporates one precision-molded aspherical element within the optical layout to minimize spherical aberrations and geometric distortions, maintaining edge-to-edge sharpness throughout the zoom range.

Super Spectra Lens Coating: Glass elements are treated with Canon’s proprietary multi-layered Super Spectra coating to suppress surface reflections, lens flare, and ghosting, ensuring color-neutral imagery and rich contrast under harsh backlighting.

7-Blade Rounded Diaphragm: Outfitted with a rounded seven-blade aperture structure that provides a smooth, pleasing background blur (bokeh) when isolating subjects with selective focus techniques.

Item Condition & Diagnostic Notes
Cosmetic & Mechanical State: Good condition. The outer plastic barrel, rubberized zoom ring, metal electronic contacts, and mount bayonet show only light signs of standard handling. The STM autofocus drive and optical stabilization mechanics operate smoothly and responsively on the bench.

Optical Condition Note: Inspection reveals some very light internal fungus on an inner element. The fungus is currently minimal, faint, and confined to the edges, meaning it does not visibly degrade contrast, color rendering, or image sharpness under normal shooting conditions. However, the lens is priced accordingly for budget-conscious shooters, technicians, or controlled-climate use.

Included Accessories: Comes equipped with a compatible front lens cap and rear lens cap.
