Canon announces RF 14-35mm f/4L IS USM lens

Canon has announced the RF 14-35mm f/4L IS USM lens, its widest RF lens to date. 

According to Canon, the new zoom lens completes the company's RF trinity of 'kitbag-friendly', compact f/4 lenses, and promises quiet autofocus via a Nano USM focus motor, a 5.5-stop optical image stabiliser (7-stops when using the EOS R5 and R6) and a build that includes aspherical and UD elements.

The RF 14-35mm f/4L IS USM will be ideal for landscape and architectural photography, as well as vlogging where content creators need a stable and broad field of view. 

The new lens weighs just 540g, and shares the same 77mm filter thread as the other F4 lenses for RF mount. It has a minimum focus distance of 0.2m and a 0.38x magnification. 

The RF 14-35mm f/4L IS USM employs three ultra-low dispersion and three glass moulded aspherical lens elements - one of which is both UD and aspherical. These all feature a non-spherical curvature which gathers light at a single point to reduce aberration and help sharpness. The glass also features Canon's Subwavelength Structure Coating (SWC) and Air Sphere Coating (ASC), to prevent ghosting and flare.

Canon says that a new rear focus design (used to enable the close focusing ability of the lens) also reduces focus breathing to less than a third of the EF 16-35mm f/4L IS USM. 

Other features include a control ring for direct control of the TV, AV and ISO settings, and a full-time manual focus ring with L-series weatherproofing.

The lens is expected to ship from late August, however no pricing has been confirmed as yet. You can find out more about the new lens at Canon.
