How does VR on a Nikon lens work ?

  1. Ok, I searched thru but could not find an answer.
    Does somebody know how the Nikon Vibration Reduction works ?
    Or is this a Nikon secret.


  2. It's pretty much the same as how Canon's IS works (and some people fight over who invented it).

    Small gyros detect lens motion and a little computer in the lens interprets this and drives small electric motors to move a specific group of elements in the lens to stabilize the image.

    Canon has an explanation of IS here which is essentially the same.
  3. Voice coils, motion sensors and some kind of prisms. You might find this at Nikon Worldwide, Japan, English, poke around. It use to be there somewhere. It’s been a long time since I’ve seen it but it was nicely illustrated and well explained.
  4. Try here...

    This is an interview with a Nikon engineer concerning the AF-S 70~200/2.8G ED-IF VR.

    The "prism" was probably a chunky, 2 elements in 1 group, that was moved by the voice coil. It's been a while.

    Here is a typical illustration surviving in temporary files of a backup. It looks like an 80-400mm f/4.5-5.6D ED VR AF Zoom-Nikkor...
  5. Carl, David thank you very much. Especially for the link to I just got my
    new 70-200. This is very interesting.

  6. As per illustration the function can be explained as follows. Small gyros, which sense the movement of camera can be used to move the lens so that the image captured can be still and clear. Gyros are widely used in aircrafts to sense its inclination with respect to earth while it is in flight.
