... the EOS R employs Dual Sensing IS that detects camera shaking with high accuracy for effective image stabilization equivalent to a maximum of 5 shutter speed stops for slower shutter speed yet sharp image stills. It also supports Dual Pixel Raw for micro-adjustment, bokeh shift, and ghosting reduction.

Equipped with Canon’s latest microprocessor, the RF24-105mm f/4L IS USM achieves 5 stops* of image stabilization—the most ever achieved by any Canon lens. The lens also supports Dual Sensing IS for stills while the video capture utilizes Combination IS, a feature in which the optical IS of the lens works together with the electronic IS of the camera body to produce a superior image stabilization effect.
* When shooting with the EOS R at a focal length of 105mm. Based on CIPA standards.

Besides Dual Sensing IS and Combination IS at up to 5stops of Image Stabilization, the lens also has Hybrid IS that corrects hand shake with high precision during macro photography.
