What does the VR mean and what does it get me? Michael Tucker  Signature-- Mike Tucker <pilgrims@earthlink.net > What does the VR mean and what does it get me? VR = Vibration Reduction (Canon's IS Image Stabilization) probably using gyroscopes or something to reduce camera shake at slow speeds. If you are too impatient for a tripod like me it's probably very valuable. If you need high speed for shooting action it will trick you into using too slow a shutter speed. I haven't tried it but would like to very much. >What does the VR mean and what does it get me? As all ready mentioned it is Nikon's image stabilization (vibration reduction) system. It allows you to take slower shutter speed (typically quoted as ~2 stops worth) photos without a tripod by cancelling out the motion of the lens. ________________________________________________________ Ed Ruf Lifetime AMA# 344007 (Usenet@EdwardG.Ruf.com) See images taken with my CP-990/5700 & D70 at http://EdwardGRuf.com > What does the VR mean and what does it get me? The only thing I would add is that Nikon apparently has different versions of VR. They say (for reasons that have never been clearly explained to me) that you should turn VR off when the camera is on a tripod, but some of the newer lenses do not have this requirement (also for reasons that Nikon does not bother to explain). I find it useful especially when a tripod is impossible or worthless, such as shooting from inside an airplane. VR will not work with most teleconverters; Nikon's new 1.7x teleconverter is supposed to work with VR, though. > VR will not work with most teleconverters; > Nikon's new 1.7x teleconverter is supposed to > work with VR, though. The VR 24-120 & 80-400 don't work with a teleconverter because the glass is too slow as I understand. The AF-S VR 70-200mm f/2.8G IF-ED is supposed to work well with the 2x TC-20E II teleconverter, I think. Can you tell me what the new 1.7x model is, I'm curious. > > VR will not work with most teleconverters; > > Nikon's new 1.7x teleconverter is supposed to [quoted text clipped - 5 lines] > > Can you tell me what the new 1.7x model is, I'm curious. The TC 17E II http://www.nikonusa.com/template.php?cat=1&grp=5&productNr=2151 Nikon's site says that this teleconverter is supposed to support VR. Nikon does not say that about the other teleconverters. >>The VR 24-120 & 80-400 don't work with a teleconverter because the glass >>is too slow as I understand.

Hmm looks the one I mentioned does kill VR, thanks for pointing that out. This one is an inch shorter and $50 more at $400. It reduces f-stop by 1.5 versus 2 stops. It also will not work on the VR 24-120 or the VR 80-400 so the only VR that benefits is the $1,500 AF-S VR 70-200mm f/2.8G IF-ED. Understand that the lenses you mention use different focusing methods. While they are VR lenses, the 24-120 is an "S" type lens, using the in-lens focusing motor and requiring the teleconverter to have the required electronic contacts to communicate with the camera body. The 80-400 is also a VR lens but has no in-lens focusing motor (it is not an "S" type lens) but uses the mechanical connection to the body. The AF bodies all carry an in-body focusing motor to drive all the normal AF lenses. No Nikon teleconverter has the required drive shaft to transmit the rotational motion of the in-body focusing motor to the lens. Some off-brand teleconverters do however. All the "S" type teleconverters (TC 14E, TC 20E and their "II" derivatives and the TC 17EII) have the required electronic connections to enable AF and VR. The change in light transmission after adding them to a lens might impede AV or VR operation, but that is another issue.

If the combined maximum aperture is smaller than f/5.6, then use lose AF capability with the D70. There are other constraints. The kit lens for example is not even physically compatible. >The AF-S VR 70-200mm f/2.8G IF-ED is >supposed to work well with the 2x TC-20E II teleconverter, I think. Works OK. It does slow the focus down on my D70. I just got back from using this combo to photograph an F-22 being escorted by some F-15s flying into LAFB in Hampton, VA. Focusing was considerable slower than just with the lens itself, and with a bit of hunting. ________________________________________________________ Ed Ruf Lifetime AMA# 344007 (Usenet@EdwardG.Ruf.com) See images taken with my CP-990/5700 & D70 at http://EdwardGRuf.com > The only thing I would add is that Nikon apparently has different versions > of VR. > [snip] What bodies to VR lenses work on? Can I hang a VR lens off my FM2? How about an F90X? ============================================================ Gardner Buchanan <gbuchana@rogers.com> Ottawa, ON FreeBSD: Where you want to go. Today. Nikon has, to my knowledge, only one "version" of VR. Uses differ in some Nikkors in that some work with tripods better than others etc., but VR is VR. VR is usable on all modern pro electronic models after the F4 (on which it doesn't work). Yes, you can mount the lens on your FM2 but obviously the VR and AF will be inoperative. It will also mount on the F90X and the AF will work but I'm not sure on the VR operation. Check Nikon's website for that info.
