What does ONOFF mean on the stabilizer of SLR camera?

Do you need to turn on the lens anti-shake function switch? On means on, off means off.

The effect of optical anti-shake function is quite obvious. Generally speaking, turning on this function can improve the shutter speed of 2-3 gears, so that hand-held shooting will not be blurred, and the effect is very obvious for novices.

According to the shaking direction and displacement of the lens, the compensation lens group adjusts the position and angle accordingly to keep the optical path stable, thus effectively overcoming the image blur caused by camera vibration.

Electronic image stabilization:

The so-called electronic anti-shake means that the whole process of anti-shake is realized by digital processing technology without the assistance and participation of any components.

At present, there are two main types of electronic image stabilization: natural image stabilization by improving camera sensitivity (ISO) and digital image stabilization by pixel compensation or other calculation methods.

Double anti-shake:

It is a digital camera anti-shake system composed of "optical anti-shake" and "high sensitivity".

Among them, "optical anti-shake" is a complex technology, which relies on the built-in precision gyroscope and a set of movable lenses of the camera to calculate and correct the light deviation caused by hand shake and avoid blurring.

The principle of high-sensitivity anti-shake is relatively simple, that is, increasing the shutter speed by increasing the ISO value of the sensitivity can also achieve the anti-shake effect.
