What does the button above vr on Nikon SLR lens mean?

"VR" on Nikon SLR lens refers to: camera anti-shake technology.

VR (Vibration Reduction) is referred to as camera anti-shake technology. It can shoot quickly when the shutter speed is reduced by three levels, and clear photos can be obtained when using a long focal length lens.

The so-called "VR" is optical image stabilization, which is short for vibration reduction. It uses two sensors in the lens to detect vertical vibration (vertical shake) and left-right vibration (left-right swing) during shooting, and uses two VCM voice coil motors to drive the vibration compensation optical system to capture the camera data after vibration, which can compensate the camera shake by moving the lens.

Advantages of virtual reality:

1. The first application of Nikon damping technology is Nikon Zoom 700VR QD, a light camera sold at 1994. It has a history of 10 years. According to the different lens sensors, damping technology can be divided into VR and VR II. VR technology can effectively reduce the shutter speed by three levels. ?

2. The lens of the new VR II system can help photographers get the same stable shooting effect, even if the shutter speed is reduced by 4 levels. This is an epoch-making value.

3. More importantly, the effect of VR shock absorption can be observed through the viewfinder, and it can also work normally when shooting the subject in AF (automatic focusing mode).

4. For the camera that compensates the vibration by CCD motion, the damping system can only be used after the shutter is released, so it is impossible to check the damping effect through the viewfinder. If you don't see the effect, you don't know the result. In autofocus mode, the subject is still shaking. With VR technology, even if the depth of field is shallow, the photographer can correctly compose and focus.
