The Canon RF 24-105mm F4-7.1 IS STM is a compact telephoto zoom lens for the company's full-frame mirrorless cameras. Its image stabilization system can reduce shake by up to 5 stops. The minimum focus distance is 13cm (5.1") in manual focus and 20cm (11.4") with autofocus. The maximum magnification is 0.5x with manual focus. A stepping motor (STM) moves the focus group smoothly and quietly. A control ring can be used for manual focus and adjusting other camera settings.
