Canon EF 70-300mm f/4-5.6 IS USM Lens

Canon EF 70-300mm f/4-5.6 IS USM Telephoto Zoom Lens (Canon EF, Black)
Versatile Full-Frame Telephoto Zoom – 70-300mm Focal Length (112-480mm APS-C Equivalent), Three-Stop Optical Image Stabilizer (IS) System with Dual Modes (Mode 1 for General Handheld & Mode 2 for Panning), Micro Ultrasonic Motor (USM) for Fast & Quiet Autofocus, Optical Formula Featuring One Ultra-Low Dispersion (UD) Element, Super Spectra Coating for Flare and Ghosting Suppression, Rounded 8-Blade Diaphragm for Pleasing Background Bokeh, Physical Zoom Lock Switch at 70mm, Native Canon EF-Mount Compatible with Full-Frame and APS-C DSLRs / Mirrorless via Adapters (Good Condition)

The Canon EF 70-300mm f/4-5.6 IS USM is a versatile, high-reach telephoto zoom lens engineered for full-frame Canon EF-mount DSLRs (providing an expansive 112-480mm 35mm equivalent focal range when mounted on APS-C sensor bodies). Designed to balance long-range magnification with a portable, hand-holdable form factor, this lens is well-suited for outdoor sports tracking, wildlife observation, airshows, travel isolation, and distant portraiture. Its broad zoom span allows photographers to move from portrait-length framing to distant telephoto reach without changing lenses, making it a dependable outdoor companion.

Sharp handheld performance is supported by Canon’s built-in optical Image Stabilizer (IS), which provides up to three stops of shake correction. The system includes two dedicated stabilization modes: Mode 1 for standard multi-directional shake correction during stationary shooting, and Mode 2 tailored specifically for tracking horizontal or vertical panning action. Optical clarity is maintained through an advanced layout of 15 elements in 10 groups, utilizing an Ultra-Low Dispersion (UD) glass element to minimize chromatic aberrations and color fringing, alongside Super Spectra coatings to control internal flare and ghosting. Autofocus is driven by a Micro USM (Ultrasonic Motor) for responsive, quiet focusing, supported by an on-barrel AF/MF toggle, a zoom lock switch to prevent barrel creep during transport, and a rounded 8-blade diaphragm for smooth out-of-focus background highlights in solid, field-tested condition.

CONDITION DIAGNOSTICS & PHYSICAL NOTES

Included Components: ESSENTIAL TELEPHOTO ZOOM OUTFIT. Supplied with the Canon EF 70-300mm f/4-5.6 IS USM lens, front snap-on lens cap, and rear Canon EF-mount dust cap. (Camera bodies, 58mm screw-in filters, lens hoods, and carry pouches sold separately unless pictured).

Exterior & Barrel Status: GOOD CONDITION. The textured black composite barrel, ribbed rubber zoom ring, forward manual focus ring, and bayonet mount show typical cosmetic signs of standard field handling. Light surface scuffs, shallow rub marks along outer edges, and moderate cosmetic wear around the barrel housing are visible upon close inspection. All white and gold printed focal length numbers, Canon Ultrasonic badging, and barrel switch markings remain intact, clean, and fully legible.

Optical Status: GOOD CONDITION. Both front and rear external optical glass surfaces are clean and free of deep scratches, cracks, chips, haze, fungus, or element separation. The internal optical assembly contains minor, faint dust particles typical of standard telescoping zooms; bench testing confirms these specks do not impact resolving power, edge contrast, or color fidelity across working apertures. Super Spectra multi-coatings remain intact.

Mechanical & Electronic Diagnostics: FULLY FUNCTIONAL. The Micro USM autofocus motor acquires focus swiftly, accurately, and quietly; the physical AF/MF switch toggles cleanly; the dual-mode Image Stabilizer engages smoothly and steadies the viewfinder image in both Mode 1 and Mode 2; the zoom mechanism extends and retracts smoothly across the 70-300mm range with consistent tension; the mechanical zoom lock switch holds the barrel securely in the collapsed 70mm position; the rounded 8-blade diaphragm stops down crisply without oil residue; gold-plated EF electronic contacts communicate Exif metadata and aperture control reliably with zero camera error codes.

KEY FEATURES & PERFORMANCE HIGHLIGHTS

Broad 70-300mm Telephoto Reach: Spans portrait-length framing to medium telephoto reach on full-frame cameras, and delivers an extreme 112-480mm equivalent reach on APS-C bodies.

Three-Stop Optical Image Stabilizer: Compensates for camera shake by up to three shutter speed stops to ensure sharp handheld captures in lower light and at full 300mm extension.

Dual IS Modes: Features Mode 1 for all-around stationary handheld shooting and Mode 2 optimized specifically for horizontal and vertical action panning.

Ultra-Low Dispersion (UD) Element: Integrated UD glass suppresses chromatic aberrations and color fringing, delivering sharp contrast and faithful color rendering.

Super Spectra Coatings: Applied across internal elements to minimize surface reflections, ghosting, and flare when shooting against bright or backlit skies.

Micro Ultrasonic Motor (USM): Provides responsive, high-speed, and quiet autofocus tracking suitable for fast-moving sports and wildlife action.

Mechanical Zoom Lock Switch: Locks the zoom mechanism at the 70mm position to prevent zoom creep when carrying the lens downward on a strap or in a bag.

Rounded 8-Blade Diaphragm: Creates natural, pleasing out-of-focus background blur and circular bokeh highlights when shooting with selective depth of field.

Compact & Portable Build: Offers substantial telephoto reach in a manageable 22.2 oz barrel that balances comfortably on DSLRs and adapted mirrorless bodies.
