Vsteretilsya here with this statement on INFO CAM. ( http: // www. Info-cam. Ru / forum / viewtopic. Php? T = 480 & amp ... r = asc & amp; start = 0 )

"Frequency samplinga VR 500 Hz. This means that to use it on exposures shorter than 1/500 completely pointless and even harmful.

In addition, VR bokeh worsens and can reduce the sharpness of the image. That is why Nikon does not collect stabilizer some top professional glass (eg 24-70 / 2. 8) 2 @ "

It really so? For example, 70-300 VR and sprinkled on the long end of the EGF has 450 - t. E. It turns out that when exposed to 500 VR has actually useless and even shake quite a possibility?

It would be nice to get more official source. Either method of verifying this statement.

Canon In this obviously does not know, t. To. 70-200 \\ 4 IS sharper and contrast 70 200 \\ 4 without IS.

Hmmm, why at such exposures VR?
I always thought that he was on the contrary, that at 1 \\ 30 shooting.

And you try to shoot something 300 mm, understand.

shake is always possible - it is on the distance to the object and its size depends on (not to mention his mobility). And this is what VR had in mind - they are in fact different.

Hmmm, why at such exposures VR?

1) when shooting with an unstable platform (helicopter deck of a small ship, and so on. D.) The stabilizer helps at all shutter speeds;

2) when using telephoto lenses stabilized optics allows you to confidently focus (with unstabilized picture sometimes dances so that "poke" AF sensor in the right place is almost impossible).

Pro deterioration bokeh and sharpness due to VR write a lot, but examples of something I had never seen.
If the regulator is faulty - yes, as a port, yesterday tried Tamron 28-300 VC, stub was clearly defective.

But neither with 18-200 VR, with any Canon 70-200 / 4 L IS some damage to the quality did not notice.

Thank you, apparently - another "urban legend." I experimented with the Nikon 16-85 VR at 200-300 exposures (shooting with a tripod, hand-VR ON / OFF) to be honest once to a definite conclusion did not come. Just interested in what will happen if the shutter speed is shorter than 1/500 known as VR included - because of the weather in the MSC to undertake such ekesperiment is not yet possible.

Rather just seems to be true. Flying inside the lens in unpredictable directions lens hardly sharpness and beauty pattern adds.

and what's wrong with that. . I myself am on the same glass often enough so I do
way on the subject - on the lens 70-300VR (nikon) conducted a series of tests. . shooting on a tripod to 300mm (450 EGF) delayed-type 1/10 on and off with VR. difference - not seen. only were smear - it Konda "strelyaesh" on the move, VR will not let go out on the operating mode (it is about 0, 3-0, 5 seconds) then yes, get messy

general - well, what problems disable stub from the lens of stabnutogo? and here at nestabnutogo include stub - difficult (do not talk about stub matrix, it is as if not the ice, stub with glass - AF and better, and made potchatelnee likely even be targeted at specific objects)

Yes I've bought a 70-300 VR also for the birds (gulls) work out - somehow not very good at D60 that wiring that without (well if suitable gallery 1 15-20). And here are very nice and D40X c those same three points of focus.

Simply interested in what will happen if the shutter speed is certainly shorter than 1/500 and VR included - because of the weather in the MSC to undertake such ekesperiment not yet possible
Well, today the weather will allow honestly think that a series of experiments on exposures in the area 1/4000 with on / off switch Stabia should show the truth. The only question is where to get shaker? Put on a cheap tripod and kicking his legs? Or drag across the floor - it will then vibrate)))

Oh! Idea! Put into the body of children's avtomobilchika and carry on asphalt

central point. There probably gave light to catch well. Bokeh though not very

"samplinga VR frequency of 500 Hz. This means that to use it on shorter shutter speeds 1/500 completely pointless and even harmful.
even if the frequency of 500 Hz Sampling, IMHO it does NOT mean that it is pointless to use a shorter shutter speed 1/500 Sampling frequency
tells us only about the frequency of oscillation that VR can register (and suppress if the drive VR can react with the same frequency).

way that is 1/500? it's time for that pixel by passing the slit. and she slit on entire frame passes during not shorter than xsync / 2

Good all the time of day.
Regarding VR. I have a Nikon D300. Lens AF-S Nikkor 16-85 1: 3, 5-5, 6G ED. In VR
two modes - normal and active. Something I do not see much difference between the disabled, normal and active VR. E. At a relatively slow shutter speed (1 / 10-1 / 90) for not very good light (Handheld) sharpness clearly walks for all modes. How not special to understand this mode generally works for me? How do I check to see that the obvious difference?
Thanks in advance.

17.02.2010 19:42:00

sharpness clearly walks for all modes
Sharpness walks or seen LUBE? These are different things.

17.02.2010 20:16:00
So let's say that the picture clearly shows that were removed from the hands. If the same light with tripod - it's OK.

17.02.2010 20:23:00

the picture clearly shows that were removed from the hands
And we would see, and then we can talk about different things. Here it is removed from the hands, VR Normal. Sharpness is quite decent, but sometimes visible LUBE.

17.02.2010 20:26:00
Well, it's a cool photo.
Now try sfotkat with table lamp with a tripod and with hands and give a link to your PC. 5 min.

Sorry for the mess, is not ready. When off as not the sharpest. Yes

principle of a clear, but somehow I do not feel it.

Yes, shot 4, 8, 1/30


17.02.2010 21:47:00

Tripod
VR is on or not? Last picture was the most dramatic. The first three smear I had not noticed. IMHO, it looks like the focus error.

17.02.2010 21:56:00
That's what confuses and that without VR turned sharply. A focus error - this is my krivorukost or that fotikom?

18.02.2010 9:40:00

And with a tripod without VR how? In
EXIF ​​images laid out no information on the focus mode and the selected points, CS3 whole thing finished. In such cases it is more convenient to use JPG-s from the camera or CNX2.

Duc, shooting in RAW, but throwing 29 megs and files through internet - is incorrect. With a tripod - VR off.
