Designed to take advantage of the EOS R System’s large-diameter mount, the RF 14-35mm f/4L IS USM features an advanced optical design that uses 16 elements arranged in 12 groups. Included are three ultra-low dispersion and three glass moulded aspherical lens elements, one of which is both UD and aspherical. Together they feature a non-spherical curvature which minimises common aberrations and ensures high resolution from edge to edge of the image. Proprietary Subwavelength Structure Coating (SWC) and Air Sphere Coating (ASC) combine to prevent ghosting and flare, enabling the lens to record with exceptional sharpness and contrast.

The 14-35mm zoom range is ideal for landscape and architectural photography and the constant f/4 maximum aperture, coupled with a 5.5-stop Optical Image Stabiliser enables the lens to be used low light conditions. Up to seven stops of shake correction can be achieved when the lens is used with a camera with In-Body Image Stabiliser (IBIS).  Autofocusing is driven by a Nano USM motor, which ensures fast, smooth and quiet operation and is ideal for use while shooting video. The lens also boasts extensive weather-resistant sealing and a minimum focusing distance of  0.2m with 0.38x magnification.

Weighing just 540 grams and less than 100 mm in length, the RF 14-35mm f/4L IS USM stands alongside the compact, lightweight RF 24-105mm f/4L IS USM and RF 70-200mm f/4L IS USM lenses to deliver a range of f/4 lenses that can suit almost any subject type. All three lenses share the same 77mm filter thread, which makes them convenient travel companions.  The RF 14-35mm f/4L IS USM is supplied with an EW-83P lens hood and LP1219 pouch.

The lens will ship from late August but pricing has not been released as yet. Several local re-sellers, including the Canon-owned SunStudios, have begun accepting pre-orders.
