Canon EF 70-200mm f/4L USM Lens

Canon EF 70-200mm f/4L USM Telephoto Zoom Lens
Professional Full-Frame Telephoto Zoom for Canon EF Mount – Constant f/4 Maximum Aperture, 1 Fluorite & 2 Ultra-Low Dispersion (UD) Elements, Ring-Type USM Autofocus with Internal Focusing, Super Spectra Coating, Focus Limiter Switch, Includes Front & Rear Caps & Dedicated Lens Hood (Well Used Condition / Internal Dust)

The Canon EF 70-200mm f/4L USM is a lightweight, professional telephoto zoom lens engineered for full-frame and APS-C Canon EF-mount digital DSLRs and 35mm film SLRs (providing an equivalent 112-320mm focal range on APS-C bodies). As a cornerstone of Canon’s premier L-series lineup, this optic delivers professional-tier resolving power in a compact, portable form factor. Covering a critical portrait-to-medium-telephoto range, it is an essential choice for sports, wildlife, event coverage, compressed landscape vistas, and portraiture.

The optical formula utilizes 16 elements in 13 groups, featuring one fluorite element and two Ultra-Low Dispersion (UD) glass elements to virtually eliminate chromatic aberrations, secondary spectrum color fringing, and distortions across the entire zoom range. Individual glass surfaces are treated with Canon’s Super Spectra Coating to curb lens flare, ghosting, and internal reflections for crisp, high-contrast results in harsh or backlit lighting. Autofocus is driven by a high-torque ring-type Ultrasonic Motor (USM) paired with an internal focusing (IF) and internal zooming design, ensuring the physical length of the lens remains completely fixed during operation while providing rapid, silent AF tracking with full-time manual focus override. A two-stage focus limiter switch (3.9′ to infinity and 9.8′ to infinity) optimizes focus acquisition speeds, while a rounded 8-blade diaphragm delivers smooth, natural out-of-focus background bokeh.

CONDITION DIAGNOSTICS & PHYSICAL NOTES

Included Components: PROFESSIONAL TELEPHOTO ZOOM LENS OUTFIT. Supplied with the Canon EF 70-200mm f/4L USM lens, dedicated lens hood, front lens cap, and rear EF bayonet dust cap.

Exterior & Physical Status: WELL USED CONDITION. The off-white metal barrel, ribbed zoom and manual focusing rings, switch panels, distance scale window, and metal bayonet mount show visible cosmetic surface wear, scuffs, finish rubbing, and handling marks consistent with regular professional field use.

Optical & Mechanical Status: FULLY FUNCTIONAL WITH OPTICAL DUST. The internal optical assembly contains standard dust particles typical of pre-owned telephoto zooms (tested and confirmed not to affect captured image sharpness, exposure, or real-world contrast). The ring-type USM autofocus motor tracks swiftly and quietly; the internal zoom and focus mechanisms operate smoothly; the electronic 8-blade diaphragm stops down accurately on compatible EOS camera bodies.

KEY FEATURES & PERFORMANCE HIGHLIGHTS

70-200mm Professional Telephoto Range: Versatile zoom span covers intimate portraits, distant action, compressed landscapes, and indoor/outdoor events (112-320mm equivalent on APS-C).

Constant f/4 Maximum Aperture: Maintains consistent exposure parameters across the entire zoom range while keeping overall weight and size exceptionally low.

Fluorite & Dual UD Glass Optics: Integrates 1 fluorite element and 2 UD elements to deliver edge-to-edge sharpness and superior chromatic aberration correction.

Ring-Type USM & Internal Mechanics: Features rapid, silent autofocus with full-time manual focus override; internal zoom and focus architecture prevent barrel extension.

Super Spectra Multi-Coating: Minimizes ghosting and flare while preserving color neutrality and deep image contrast in direct lighting.

Focus Range Limiter: Dedicated barrel switch allows selection between full range (3.9 ft to infinity) and restricted range (9.8 ft to infinity) for faster AF responsiveness.

Rounded 8-Blade Diaphragm: Produces smooth, creamy background defocus and round specular highlights for clean subject separation.

Teleconverter & Accessory Compatibility: Fully compatible with optional Canon EF 1.4X and EF 2X extenders as well as an optional rotating tripod mount ring.
