Dual I.S. Possibilities
The Body I.S. (Image Stabilizer) in the LUMIX G9 is dramatically improved, making it possible to use 6.5-stop slower shutter speed. This is achieved by a more accurate calculation of shake in various shooting conditions, utilizing information of angular velocity and motion vector acquired not only from the gyro-sensor but also from the image sensor and accelerometer sensor.
Combining B.I.S. (Body Image Stabilizer, 5-axis) and O.I.S. (Optical Image Stabilizer, 2-axis), the 5-axis Dual I.S. (Image Stabilizer) 2 in the LUMIX G9 compensates for larger movements that were conventionally uncontrollable. Maximizing both O.I.S and B.I.S. is highly beneficial in telephoto shots and in adverse situations, such as at night or with one-handed shooting.
