Canon EF 16-35mm f/4L IS USM: full-frame L-series wide-angle zoom with constant f/4 aperture, 4-stop IS, USM AF, and weather-sealed construction.

The **Canon EF 16-35mm f/4L IS USM** is a premium L-series wide-angle zoom lens built for Canon EF-mount full-frame DSLRs, delivering a versatile 16-35mm focal range with a rock-solid constant f/4 maximum aperture. Its sophisticated optical design — featuring two Ultra-Low Dispersion elements and three Aspherical elements — ensures exceptional sharpness, minimal chromatic aberration, and accurate color rendition across the entire zoom range.

Designed for photographers who demand reliability in any condition, this lens combines a 4-stop Optical Image Stabilizer for blur-free handheld shooting with a fast, near-silent ring-type USM autofocus system. Weather-sealed construction and a protective Fluorine coating on exposed elements make it a dependable companion for landscape, architectural, and travel photography in the most challenging environments.

### Key features

- **Constant f/4 Aperture:** Maintains consistent exposure and viewfinder brightness throughout the entire 16-35mm zoom range, ideal for reliable wide-angle shooting.

- **4-Stop Optical Image Stabilizer:** Dramatically reduces camera shake blur, enabling sharper handheld images in low light and at slower shutter speeds.

- **Superior Optical Design:** Two Ultra-Low Dispersion and three Aspherical elements work together to eliminate chromatic aberrations, distortion, and spherical aberrations for outstanding clarity.

- **Fast, Silent USM Autofocus:** Ring-type Ultrasonic Motor with internal focusing delivers quick, precise, and near-silent AF with full-time manual focus override — perfect for stills and video.

- **L-Series Weather Sealing + Fluorine Coating:** Dust- and moisture-resistant build combined with a smudge-repellent Fluorine coating on front and rear elements ensures durability in tough outdoor conditions.

- **Pleasing Bokeh with 9-Blade Diaphragm:** Rounded nine-blade aperture produces smooth, natural out-of-focus backgrounds for selective focus and creative depth-of-field techniques.
