How VR works

[SkyEye]

With Nikon announcing more VR lenses, and the long term forecast being for more, this might be a good time to discuss exactly how VR works. Is it some sort of motion dampening built in to the lens? Or is something else going on?

It has motion sensors that detect if you move the camera and then one lens element that is shifted to correct against teh motion. QUite nice explained on Nikons Web Page though.

As I understand it, Accelerometer's in the camera's body feed data to the lens. With that data the lense moves lens elements to compensate for instablility (movement or shake).

Do you have a link? I can't seem to find it on Nikon's USA site.

Thanks,

Does it work with the D100 ?

Yep!

Is Nikon offering their 4 extra years (when you send in the warranty card) on these models? Looks to me like you might be in for a major price tag if you ever had one of these things repaired.

If the sensors were in the body, then you would have to upgrade your

D1s, D1x/hs and D100s for VR to work. The system works very well and does not cause as big a drain on batteries as you might expect. (I am speaking from experience with Canon's IS system, not the Nikon VR system. But the tweo seem to be very close in technology and functional ability)

...this might be a good time to discuss exactly how VR works.

If you really want to know how it works, the Nikon patents are very clear. If you go http://www.uspto.gov , click on "search patents", and then try the following, you'll understand quite well:

US# 6272288, 6285501, 6320698, 6424465

One of the surprises in this series is #6424265, which describes a "Front tele-converter, and front tele-converter having vibration-reduction function" that is a greater than 1.9x TC design with VR built in that goes in FRONT of your regular lens! If they productize this, as a "TC20VR" I'll say right now that I'm ready to buy the first one...

I read somewhere that the VR function is based, at least in part, on input from the AF sensors in the body, to the lens?

I just saw the page mentioned above that shows the position of the sensors and lens element that moves.

Nikon VR only works on
F5, F100, N80, D100, D1, D1h, D1x

It will not work with the N90s or anything below the N80, so the body does work into the equation somehow. Just not sure how?

If the sensors were in the body, then you would have to upgrade your
D1s, D1x/hs and D100s for VR to work. The system works very well
and does not cause as big a drain on batteries as you might expect.

Funny that the body would have an effect on VR. I don't think there is any problems using IS on any EOS body. I would have thought the IS/VR system could be designed to work on any body.

Maybe the other poster who said that the AF system is tied to VR is correct (I need to do some more research). Well the good news is it will work on any Nikon DSLR.
