Canon EF 16-35mm f/4 L IS USM Lens

The Canon EF 16‑35mm f/4L IS USM Lens is a professional‑grade ultra‑wide‑angle zoom lens designed for Canon EF‑mount full‑frame and APS‑C DSLR cameras. Part of Canon’s renowned L‑series, this lens delivers excellent optical performance, durable build quality, reliable autofocus, and enhanced handling — making it ideal for landscape, architecture, travel, documentary, and environmental photography.

Ultra‑Wide Zoom Range & Optical Design

With a 16–35 mm focal length and a constant f/4 maximum aperture, this lens offers a versatile field of view perfect for capturing expansive scenes, tight interiors, and dynamic perspectives. Its sophisticated optical construction includes 16 elements in 12 groups with three glass‑molded aspheric lenses and two Ultra‑Low Dispersion (UD) elements that significantly reduce distortion, chromatic aberrations, and color fringing at all focal lengths.

Image Stabilization for Sharp Results

The built‑in Optical Image Stabilizer (IS) helps compensate for camera shake, providing up to four stops of stabilization advantage — especially helpful when shooting handheld in low‑light conditions or at slower shutter speeds without a tripod.

Fast, Quiet Autofocus & Manual Control

A ring‑type Ultrasonic Motor (USM) ensures fast, precise, and near‑silent autofocus performance, while full‑time manual focus override lets you fine‑tune focus without switching out of autofocus mode.

Optical Quality & Bokeh

A 9‑blade circular diaphragm produces pleasing background blur and smooth out‑of‑focus highlights. Advanced lens coatings help reduce ghosting and flare, even in backlit conditions, resulting in rich contrast and improved color fidelity.

Durable Construction & Weather Resistance

As an L‑series lens, it features dust‑ and moisture‑resistant construction, so you can confidently shoot outdoors in challenging environments. The lens also includes a protective fluorine coating on the front and rear elements to repel water and oil and make cleaning easier.

Close‑Focusing & Handling

With a minimum focusing distance of 0.28 m (0.92 ft) and a maximum magnification of approximately 0.23x, this lens offers flexibility for capturing dynamic foreground details in wide shots. Its compact design balances performance with portability.
