Nikon what is vr




















VR not correcting right is a bit like tripod mount slop fixed with a Really Right Stuff Long Lens Support or ringing vibrations in the tripod legs fixed by using the right legs for your equipment : you don't see it until it's gone, and even then usually only if you're pixel peeping. They expect to be able to catch every bit of detail and blow it up into a large print. As always on this site, you need to understand that I always write about the search for optimal data.

If you're shooting with a mm on a D and putting x images on the Web from that, well, whether the VR missed doing its job by a little bit probably isn't so important. Turn VR off and turn the camera off before removing the lens from the camera. So always turn the camera off before removing a lens. If there are more questions on VR I'll address them in the Discussion at the bottom of this page or additional articles. Until then, here's your motto: VR stays off unless I specifically need it.

It appears most people just want to be told "use it for X, don't use it for Y. Taking shortcuts with decisions ultimately leads to less-than-optimal results. For casual shooting, shortcuts perhaps work just fine for most people, and I've suggested a bunch in this article.

But for serious shooting where quality matters, a good photographer is always evaluating, always testing. In many ways, digital is great for that, as we have an immediate feedback loop and can test a setting assumption almost immediately, plus we have the ultimate loupe in our large computer monitors.

Thus, one other point I'll make is that I can't tell you every possible time you need to use VR and every possible time you shouldn't. What I do know is that when VR has been on when it shouldn't be, my images suffer a bit.

And yes, when I shoot without VR on when it should be, my images suffer, too. However, generally I know when I'm imparting substantive motion to the camera during shooting. Thus, VR is off unless I know that I'm imparting motion, and then I only turn it on if I can guess—and verify with a field test—that it will remove that motion.

One thing I've noticed is that those of us who shot with long lenses back in the film days prior to VR aren't quite so fast to turn it on as someone picking up a camera today. Part of that is the marketing message "up to four stops better! We either had to correct the underlying problem or not shoot. Thus, we tend to know when we're on the margin where VR might be helpful. I'd argue that leaving VR on and turning it off only when you see a degradation which may be too late if you're seeing it when you get home and looking at images on your monitor isn't easily learned.

Leaving VR off and turning it on only when you see a degradation is much more easily learned. Active Mode has to do with looking at vibrations that are human caused e. However, Active Mode disappeared on many recent lenses, and something called Sport Mode appeared. Sport Mode is very different.

Sport Mode tries to keep the viewfinder stable when shooting moving subjects. Simple as that. The lenses that do this are:.

Nikon eventually got around to documenting why they believe a lens-based VR system is better than sensor-based stabilization. They made four points:. This standardized test tries to give you a sense of how well the stabilization systems work in identical circumstances. Here are the current numbers:. What Nikon meant is that VR does not start unless you've partially pressed or fully pressed the shutter release. But when you went to take the shot pressing the shutter release would activate VR at the last possible moment.

Enough of us complained that VR actually helps during focus that Nikon made the change to the current high-end cameras that activates VR even if you're only pressing the AF-ON button.

Previous to that, we had to do the two button shuffle: half press the shutter release to get VR working, then press the AF-ON button to get a stabilized focus action.

If something is moving you, use Active. If it's just you moving the camera, use Normal. If your subject is moving, you still need a shutter speed that will stop that movement. Expecting VR to remove all motion including subject motion is something everyone has to get over: VR doesn't remove all motion, it only removes camera motion.

If you're panning correctly, VR should probably be On, and set to Sport mode, if available Yet another aspect of VR that confuses people is activation. If you rely upon VR and use flash, use an external flash instead of the internal one if you can.

Thus, we have another rule before we get to the real rule: You MUST read your lens manual and see what it says about use on tripods. Two basic possibilities exist: The manual says turn VR off when on a tripod sometimes adding "unless the head is unsecured" The manual specifically says that the VR system detects when the camera is on a tripod Okay, I lied. Forget what the manual says.

Yes, in practice, the new VR seems to do a slightly better job, but it's unclear as to why it does a better job. I've had one VR failure that needed repair and I know of others who've had similar failures. Still, it's rare that a lens has a mechanical failure, though adding the complexity of the VR mechanics certainly must increase the likelihood of encountering a problem.

I'll bet that it is low. When you run batteries way down and activate VR it appears that the VR system can sometimes demand more power than the camera can supply instantaneously. The result is "jumpy VR" as the VR circuitry cuts in and out.

But see the "jumps after a shot" comment, below. After all, the VR elements are probably moving between samples. And I believe you get burned by it more often than you'd get burned by having VR off. And this can be important in some instances. It's one of the reasons why I argued that not putting VR into the original mm lens was one of Nikon's bigger mistakes in the first digital decade. If you're moving the camera enough that the autofocus sensor s you're using isn't staying stable on the point you want focused, there's a chance focus will shift to someplace you don't want it.

At wide angles, the AF sensors can easily get distracted by backgrounds. Nikon vaguely warns about this in their manuals fifth example, D manual page So if you're moving the camera enough that the background is getting onto that autofocus sensor with regularity, that can be a problem, and VR might help. Note that the Nikon VR system operates differently for pre-release focusing: the viewfinder image is stabilized, which means the VR elements may eventually move well off center to provide a stable view also impacts focusing, see question just above.

But during the exposure the system does a few different things. First, it re-centers the VR elements while flipping up the mirror. Second, it uses a different algorithm for doing its correcting. Personally, I think this really gets down to a handling issue, though.

One of the primary camera motions that VR is often correcting is the "shutter release stab," which tends to impart a forward or backwards tilt in the camera. Proper use of a monopod tends to mostly remove that component, leaving side-to-side as the primary camera movement needing correction. So it starts to depend upon what's causing that side-to-side motion. Following action that moves in one direction?

That's panning see above, and select Sport VR mode. Following action that moves back and forth? Be careful of the shutter speed. Many Nikon and Canon lenses now come with vibration reduction Nikon and image stabilization Canon options that you can either turn on or off. The advantages of VR and IS, is that you can achieve sharper photographs when hand holding your camera, especially in darker lighting. For example, sporting events, museums or photographing moving animals like birds or fish.

The value is achieved when a DX-format compatible lens is attached to a DX-format D-SLR camera and zoom lenses are set at the maximum telephoto position or when an FX-format compatible lens is attached to an FX-format D-SLR camera and zoom lenses are set at the maximum telephoto position.

Nikon VR originates in the lens, not in the image sensor, which means that algorithms optimized to an individual lens are applied. Another advantage of lens-based VR is that a separate algorithm confirms the stabilization effect when you press the shutter release button halfway, giving you the freedom to compose your image more easily.

Nikon VR lenses use two angular velocity sensors, one that detects vertical movement pitch , the other, horizontal movement yaw , with diagonal motion handled by both sensors working together. The sensors send angular velocity data to a microcomputer in the lens, which determines how much compensation is needed to offset the camera's shake and sends that information to a duo of voice coil motors that move selected lens elements to compensate for the detected motion.

What does this mean in practical terms? It provides you with up to four stops of "hand-holdability," delivering dramatically sharper images in a wide range of conditions. Not all anti-shake technologies are the same. The in-camera anti-shake technology used by some manufacturers relies on a process that actually shifts the image sensor, and its performance benefit is generally agreed to be limited to about one-and-one-half to two stops.

For Nikon photographers, an additional two stops of VR performance capability can easily be the difference between a blurry picture and a beautiful sharp one. But the benefits of Nikon VR aren't limited to shutter speeds. Consider shooting on an overcast day at a medium ISO where greater depth-of-field might be desirable.
