Canon EF 16-35mm f/2.8L II USM Lens

Canon EF 16-35mm f/2.8L II USM Lens
Professional Full-Frame Ultra-Wide Zoom for Canon EF Mount – Fast Constant f/2.8 Maximum Aperture, Advanced L-Series Optics (3 Aspherical Elements & 2 UD Elements), High-Speed Ring-Type Ultrasonic Motor (USM) with Full-Time Manual Override, Internal Focusing (IF) Design, Circular Diaphragm, Weather-Sealed Construction, Includes Front & Rear Caps plus Dedicated Petal Lens Hood (Excellent Condition)

The Canon EF 16-35mm f/2.8L II USM is a professional-grade ultra-wide-angle zoom lens designed for full-frame Canon EF-mount DSLRs (also fully compatible with APS-C bodies providing a 25.6-56mm equivalent range, and EOS R mirrorless systems via EF-EOS R adapters). Built to rigorous L-series optical and mechanical standards, it delivers high edge-to-edge sharpness and high contrast across the entire zoom range, making it a standard choice for landscape photography, architectural interiors, photojournalism, wedding receptions, and video production.

The optical formula utilizes 16 elements in 12 groups, incorporating three high-precision aspherical elements of varying types (ground glass, replica, and Glass Molded / GMo) alongside two Ultra-Low Dispersion (UD) elements to correct chromatic aberrations, field curvature, astigmatism, and distortion. A bright, constant f/2.8 maximum aperture ensures consistent exposure settings throughout the zoom range and excels in low-light environments. Autofocus is powered by a high-torque ring-type Ultrasonic Motor (USM) featuring an internal focusing mechanism for fast, whisper-quiet AF performance and seamless full-time manual focus override. Built for demanding professional field work, the lens features comprehensive dust- and moisture-resistant weather sealing, an 82mm front filter thread, and a circular aperture diaphragm for smooth, natural background bokeh.

CONDITION DIAGNOSTICS & PHYSICAL NOTES

Included Components: Supplied with the Canon EF 16-35mm f/2.8L II USM lens, Canon 82mm front snap-on lens cap, Canon EF-mount rear bayonet dust cap, and authentic Canon dedicated petal-style lens hood (EW-88).

Exterior & Physical Status: EXCELLENT CONDITION. The matte black composite and metal barrel, ribbed rubber zoom and focus rings, distance scale window, AF/MF switch, hood bayonet track, rubber weather-sealing mount gasket, and metal EF-mount bayonet show minimal signs of light handling.

Optical & Electronic Status: FULLY FUNCTIONAL. Optical glass elements are clean and free of scratches, haze, or fungus; the internal zoom mechanism operates smoothly; the ring-type USM autofocus locks swiftly, silently, and accurately; full-time manual focus engages properly; the electronic circular diaphragm stops down reliably across all apertures.

KEY FEATURES & PERFORMANCE HIGHLIGHTS

Ultra-Wide 16-35mm Focal Range: Spans dramatic ultra-wide perspectives to classic wide-angle documentary fields of view.

Fast Constant f/2.8 Maximum Aperture: Maintains consistent light transmission and depth-of-field control throughout the zoom span.

Advanced Optical Architecture: Features 3 distinct aspherical elements (ground, replica, GMo) and 2 UD glass elements for corner-to-corner clarity.

Ring-Type USM Autofocus: High-speed, near-silent autofocus drive delivers responsive predictive tracking and instant full-time manual override.

Internal Focusing (IF) Mechanism: Keeps physical barrel length fixed during focusing with a non-rotating 82mm front filter thread.

Weather-Sealed L-Series Build: Tight gasket seals protect internal electronics and glass against dust, moisture, and adverse weather conditions.

Circular Aperture Diaphragm: Yields smooth, rounded out-of-focus highlights and pleasing background bokeh for wide-angle portraiture.

Included Dedicated Lens Hood: Petal-shaped EW-88 hood blocks stray oblique light to prevent flare while providing front element physical protection.
