Nikon Lens Vibration Reduction
Vibration reduction v r okay, so this compensates for your hand movements, there's, a gyro in your camera that can tell when you're twisting the camera up and going side to side, and it can help out for shooting under low light conditions, or whenever you can shoot it, lower shutter speeds. So this two hundred five hundred millimeter lens let's say you're at five hundred. You should probably have one five hundredth of a second selected in order to just stop the movements of your hand. If this has three stops of stabilization, we could shoot down a sixteenth of a second. If we have four stops, we could shoot down a thirtieth of a second. So for low light situations, very helpful doesn't work out for fast action sports, because we need fast shutter speeds to stop their action. But for hand holding under low light, it can really help out. Now, what it's doing is it's using and as complicated as the lens was before at a v r unit and now you got the focusing team says, okay, we got this len...
s perfect, everything moves back and forth just right, and the v r team comes in and says, yeah, we're going to put a whole bunch of lenses right in the middle, and they're going to go up and down while you're focusing, and we want to keep everything in focus. So is you tilt the camera. There is an independent group of lenses that is keeping the image focused and in place on the sensor itself and the fact that it can do this. Wow. Auto focusing and tracking subjects is just it's phenomenal to me. So that's what's happening in the system. Now, the original v r system has three stops a stabilization so you can use your lands about three stops effectively slower in shutter speeds than you would normally be ableto hand hole. They then came out with v r two, which is an improved technology. It now helps upwards of four stops of stabilization. Okay, john, question for you. I got this eighteen to fifty five lands and it says d v r two does this have tr to technology in it because it says it on the label? No, what type of v r system is in my lens? Well, you'll have to look that up online it happens to be the art to technology but you said the car to doesn't mean it's very hard to know that we are two means it has v r and the two means that this is the second generation eighteen to fifty five g lens that they've made and so the lens will not tell you on the outside whether it's v are one or two and if you want to try to find this information, you could do two things you can spend the next two hours looking this up online or you can look at the next slide where I've done the research for you and so there are a number of lenses that have the are too some of them say v r two on them because they're second versions of that focal inc aperture lands some of them just say v r but they have the new v our technology in there this is where things get a little complicated and so most of all they're fairly current lenses have this now as we get into v r you're going to find a different levels of lenses you have different switches on your lands is the most basic is turning it on and off okay, you're going to turn it on for general handheld photography it's fine it's good for pani also now there are some and good reason to believe this believe that you should not turn on v r unless you really need it so let's say you're shooting pictures of birds in flight at a thousandth of a second, you don't need the r for that, okay? Because you have a fast shutter speed that stops your emotion, and so if you don't need it, it is instituting a whole nother layer of movement, which could affect focusing. You should turn this off if you are on a good, steady tripod, because there's essentially a feedback system where it starts looking for its own movement, even though it's not moving and can cause a blurry image. So if you're on a tripod, turn it off a newer level of vibration reduction, we'll have an on off switch, but it will have a normal and active mowed down here. Normal is your standard handheld action. The nikon cameras will detect panning and will adjust for that pan emotion active is a little bit different situation it's when you are standing on a platform that is moving, whether that's, a plane or a boat or a train car, or who knows what else a skateboard. Okay, as long as it's the movement is coming from something else because they've designed this movement for your handheld movement and the vibrations that you might feel in a car or a different type of vibration than what you would naturally generate holding a camera and so active means you're shooting from another vehicle. Another newer style is one that actually has a tripod mode on it, and this is for some of their big telephoto lenses, so we have normal once again, handheld has the panning detection. If you do put it on a tripod, you could put it on a tripod, and it still is using vibration reduction. But now it notices that it's on a tripod and the type of movement it's likely to have his possibly wind movement and so that's kind of a different type of movement that you're gonna have. And the on ly cameras that have this tripod mode are a couple of their really big telephoto lenses. We're not done yet one more the newest cameras have a new sport mode, so we have the normal, which is our standard v r but now the new sport mode, it limits the vibration to the minimum needed so in the viewfinder, it is actually easier. Well, the problem, the reasons, the problem that this is solving is that when you're a sports photographer and you got that let's say, I think it downhill skier there zoom in across and they're kind of bouncing their way down and you're trying to keep them in the frame well, the vibration reduction would have this jell o effect that it was kind of hard to keep him in frame because the camera you were fighting the camera to keep things in frame. And so what this has done is it's lightened that effect so that you can track your subjects more easily. And so, it's, really, for the high end professional sports photographer and it's, exactly on the lenses that they might buy. And so it's. Not something that most of us are going to see on our day to day lenses.
