您可以試試把vr關閉和vr打開的情形各拍一張就知道了

d500+540e,如果用好的腳架加雲台

快門在1/160以上,應不太容易產生微震

你可以設在1/200,開vr和不開vr各拍一張就可以看出差別

還是一樣,拍張千元鈔票

設在6米處

拍一張看看他的細節

如果可以,順便拍一張LV的

你就知道差別在那了.....

試試看吧

不試你永遠不知道差在那的


540E的水平是很高的,至少可以達到這的效果的

上腳架要不要開VR?
很值得探究的問題,楊大,這個值得深入來探究一下!


基本上,探討這個之前,應該先釐清幾個點
1. Nikon VR的作動方式及原理
2. VR對畫質的影響
3. VR I 跟 VR II的差異性
4. 相機晃動跟反光原件(微震)的差異性


這幾個點搞清楚了,你可能才會比較明瞭,VR能幫你消除什麼,不能幫你消除什麼?消除的同時,你又會喪失什麼?




手邊沒電腦,幾個簡單的資訊,有時間先參考一下
1、

2、

the level of shake is below the threshold of the system’s detection capability, use of the VR feature may actually add unwanted blur to the photograph, therefore you should shut it off in this situation. Remember that the VR lens group is normally locked into place. When the VR function is active, the VR lens group is unlocked so it can be moved by the electromagnetic coil surrounding the elements. When there’s not enough motion for the VR system to detect, the result can sometimes be a sort of electronic ‘feedback loop,’ somewhat analogous to the ringing noise of an audio feedback loop we’re all familiar with. As a result, the VR lens group might move while the lens is on a tripod, unless the IS function is switched off and the VR lens group is locked into place.Vibration reduction or VR/IS/OS is a great feature and is in my opinion well worth paying the extra dollars for – especially if you shoot a lot of lower light shots. 


Nikon’s VR System offers Normal mode and Active mode, original technologies to help you cover various shooting situations. In Normal mode, slow and wide camera movement is regarded as recomposing movement and VR operation is controlled accordingly. In Active mode, however, even large amounts of camera movement are compensated for to give a smooth viewfinder image. This mode is quite useful when shooting from a moving vehicle or some other unstable position. 


A tripod is generally believed to prevent image blur, but camera shake can occur due to the movements of the quick-return mirror or shutter curtain, or winds. This camera shake movement has different characteristics compared to normal camera shake caused by handheld shooting. Nikon’s VR technology makes it possible to detect (Tripod detection) and compensate this type of camera shake, as well. (Note: Some VR lenses do not have this function.)


According to Nikon.


The Vibration Reduction technology built into some Nikon lenses can reduce or eliminate vibration during shooting. When the camera is on a tripod there will be very little (if any) movement so the question arises if VR should be used or not.


There are two techniques when using a camera/lens mounted on a tripod; keeping the pan/tilt head loose or fluid (when panning or moving with a subject) and keeping the pan/tilt head locked down and rigid while using a cable release (time exposures or for the new HDR techniques).


With the following lenses/cameras VR should be "Off" when the camera is mounted on a tripod and the pan/tilt head is locked down and using a cable release:
105mm f/2.8G ED-IF AF-S VR Micro Nikkor
18-200mm f3.5-5.6 ED-IF AF-S VR DX Zoom-Nikkor
24-120mm f3.5-5.6G ED-IF AF-S VR Zoom-Nikkor
70-200mm f2.8G ED-IF AF-S VR Zoom-Nikkor
80-400mm f4.5-5.6D ED VR AF Zoom-Nikkor
70-300mm f4.5-5.6G IF-ED AF-S VR Zoom-Nikkor
Coolpix 8800


With the following lenses/cameras VR should be "On" when the camera is mounted on a tripod and the pan/tilt head is loose (fluid) while using the cameras shutter release button:
105mm f/2.8G ED-IF AF-S VR Micro Nikkor
18-200mm f3.5-5.6 ED-IF AF-S VR DX Zoom-Nikkor
24-120mm f3.5-5.6G ED-IF AF-S VR Zoom-Nikkor
70-200mm f2.8G ED-IF AF-S VR Zoom-Nikkor
80-400mm f4.5-5.6D ED VR AF Zoom-Nikkor
70-300mm f4.5-5.6G IF-ED AF-S VR Zoom-Nikkor
Coolpix 8800


Nikon VR technology in the following lenses can detect minute vibrations that emanate from tripod legs.With the following lenses VR can be "On" when the camera is mounted on a tripod for either technique:
200-400mm f4G ED-IF AF-S VR Zoom-Nikkor
200mm f2G ED-IF AF-S VR Nikkor
300mm f2.8G ED-IF AF-S VR Nikkor


For all lenses VR should be "On" when the camera/lens is used on a monopod.

我以為您現在人在忙,沒想到還有時間上來放毒


延續剛剛話題,簡單來說:
1、VR的R是reduction ,也就是減少的意思,並不能完全防止。
2、VR的作動,需要訊號的偵測及浮動鏡片的啟動。而多了這些程序,對焦及畫質一定有影響。
3、訊號的偵測到啟動,一定要大於『閾值」才會作用,已經架在腳架上了,假設場地夠穩,腳架雲台夠穩,VR真的會作動嗎?
4、低於安全快門時,相機的輕微震動,足以啟動VR嗎?
5、當半按快門,VR作動鎖定後,再來的震動是來自反光鏡本身,也就是我們一般常說的『微震』,這時VR有多少功用?


以上這些,應先思考看看。

話說,你有好多的資料哦

那像我,都是土法練鋼,慢慢打.............

你還是要多回答些問題

我貼圖就好

H大太客氣,還專門拍張照片來

非常謝謝

~~~~~~~~~~~~~~~~~~~~~~~~

小店招待不周之處請包涵

大家就當自已家一樣

以後大家就自便啦......................


~~~~~~~~~~~~~~~~~~~~~~~~~

這是2014年專門跑下去屏東拍的大紅鸛,當時也算是迷鳥

還記得拍到一半就遇到漲潮

緊急撤退時一不小心就踏進了流沙池中

一下子就直接沉到淹到大腿中央

還好把腳架往下插,才止住下沉......

據說我之前還有請空警隊來救的

我運氣比較好,還有朋友可以救我....


不過很機車的是

他們是笑著把我的狼狽樣先拍下來,

然後再救我的砲,最後才救我的人.......


~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

模擬一下傳說中的德味......

最近在研究那台相機,沒錢買,只好用nikon的d800e來模擬一下

當然

畫虎不成反類犬的機會很大......
