The Canon RF 14-35mm f/4L IS USM is a full-frame wide-angle zoom lens designed for the Canon RF mirrorless mount. Its 14mm to 35mm focal length range makes it well-suited for landscapes, architecture, and environmental portraiture where broad coverage matters.

The 77mm filter thread accommodates a wide range of standard filters, while the 540g weight keeps the lens manageable for extended shoots. Both autofocus and manual focus are supported, and the lens is purpose-built for the RF mount ecosystem.
