The three essential fast aperture, high performance RF L-series lenses with image stabilization
The RF 15-35MM F2.8L IS USM and RF 24-70MM F2.8L IS USM are the first fast aperture zoom lens to feature Canon’s Nano USM technology. This technology uses a miniature ultra-sonic motor to drive the focusing system linearly delivering extremely fast and silent focusing, making it ideal when shooting video and stills.
Like all RF lenses, a programmable Control Ring on the lens barrel allows the you to change exposure settings instantly without taking your eye away from the viewfinder. ISO, exposure compensation, shutter speed or aperture can be assigned to this control ring via the camera’s menu.
