With a focal length of 14mm at the wide-angle end, the RF14-35mm F4 L IS USM achieves a focal length range that is 2mm wider than its EF series counterpart¹, making possible a greater range of visual expression and enabling photos with an enhanced sense of perspective. Thanks to its 14mm-35mm focal length range, the lens is ideal for shooting such subjects as landscapes, buildings, everyday scenes and portraits.

Featuring an optical design that incorporates 16 elements in 12 groups, including two UD (Ultra Low Dispersion) lenses, one aspherical UD lens and two glass-molded aspherical lenses, the RF14-35mm F4 L IS USM mitigates various aberrations that result in image degradation, to achieve high image quality across the entire zoom range. What’s more, the lens’ compact and lightweight body utilizes camera-side electronic distortion correction² and measures approximately 99.8mm in length and weighs approximately 540g, making it very easy to carry.

When equipping the EOS R5 (released in July 2020) with this new lens, users can enjoy up to 7.0 shutter speed stops³ of image stabilization (IS) for stills photography and a high level of IS during video shooting through the combined IS of the camera body and lens. In addition, when used with the EOS R (released in October 2018), which does not have in-body image stabilization, the lens achieves up to 5.5 shutter speed stops³ of image stabilization.
