Being smaller and lighter while maintaining a constant maximum aperture of f/4 across its focal length makes this a very nifty lens for those who requires wide-angle to mid-telephoto coverage. Being the first full-frame L lens to be powered by the Nano USM, RF24-105mm f/4L IS USM provides responsive smooth focusing—suitable for video recording. With its image stabilisation of up to 5-stops, you can achieve sharp images shooting handheld.
