Hybrid IS (In-lens Image Stabilisation)

The idea of equipping macro lenses with an image stabilisation (IS) mechanism has been around since the introduction of IS technology. However, to make it a reality, it is necessary to correct not only conventional camera shake (angular shake), but also "shift shake", which becomes more pronounced as magnification increases. This is because, while camera movement parallel to the image plane has little effect when shooting distant scenery such as landscapes, in macro photography, even the slightest movement will result in a shift blur of the captured image. Both kinds of shakes must be detected accurately and corrected. This marked the beginning of the development of Hybrid IS.

It will correct angular shake and shift shake simultaneously. The solution was the use of two sensors and a new algorithm. Hybrid IS incorporates an acceleration sensor in addition to a conventional vibration gyro (angular velocity sensor). The newly developed algorithm calculates the amount of shake based on camera movement detected by the two sensors. Through precise control of the optical image stabilisation, this lens became the world's first interchangeable SLR camera lens capable of simultaneously correcting both angular shake and shift shake.

Hybrid IS achieves a significantly higher keeper rate, even in handheld 1:1 macro shooting, which had been difficult until now. It enables high-precision handheld macro photography, even in locations where a tripod cannot be used or in low-light situations. The EF100mm f/2.8L Macro IS USM, the first lens to feature this technology, has become widely popular and has greatly changed the world of macro photography. Hybrid IS is also equipped in the RF-mount RF100mm f/2.8L Macro IS USM, which enables 1.4x magnification. Through coordinated control with the camera body, it delivers an exceptionally high level of image stabilisation of up to 8.0 stops*, further expanding the possibilities of handheld macro photography.
