Optical anti-shake technology does not make the fuselage shake, but relies on the structure of special lens or CCD photosensitive element to minimize the image instability caused by shake during use.
Canon and Nikon are the main representatives of anti-shake through lens group. They rely on magnetic force to wrap the suspension lens, thus effectively overcoming the image blur caused by camera vibration, which is more obvious for digital cameras with large zoom lenses.
Extended data
Nikon's anti-shake principle IS basically the same as Canon's IS anti-shake system, which uses the floating lens in the lens to correct the "optical axis deviation". It consists of a detection part, a lens group for compensating vibration and a driving control part. The electronic shock absorption system in the lens detects the slight vibration of the lens, corrects the lens position inside the lens in real time, and effectively reduces the influence of external vibration on the final camera imaging.
The gyroscope in the lens detects the tiny movement, sends the signal to the microprocessor, calculates the displacement that needs to be compensated immediately, and then compensates the lens group according to the shaking direction and displacement of the lens, which effectively overcomes the image blur caused by camera vibration.
