An optical image stabilizer (OIS, IS, or OS) is a mechanism used in still or video cameras that stabilizes the recorded image by varying the optical path to the sensor
This technology is implemented in the lens itself, as distinct from in-body image stabilization (IBIS), which operates by moving the sensor as the final element in the optical path.
The key element of all optical stabilization systems is that they stabilize the image projected on the sensor before the sensor converts the image into digital information. IBIS can have up to 5 axis of movement: X, Y, Roll, Yaw, and Pitch. IBIS has the added advantage of working with all lenses.
Benefits of OIS
Optical image stabilization prolongs the shutter speed possible for handheld photography by reducing the likelihood of blurring the image from shake during the same exposure time.
For handheld video recording, regardless of lighting conditions, optical image stabilization compensates for minor shakes whose appearance magnifies when watched on a large display such as a television set or computer monitor.[6][7][8]
