new micro-nikkor 105: VR works well for macro

I have seen skeptical posts on dpreview on the effectiveness of VR for macro shots, in complete contradiction with my own experience with the 80-400VR+Canon 500D close-up in the field.

A french guy had actually the opportunity to try the new AF-S 105 VR, and he posted his impressions on his site (in french) with some examples shot handheld at slow shutter speeds:

http://simpho.free.fr/forum/vr105.html
http://simpho.free.fr/forum/vr105_2.html


His initial impression is that VR helps a lot, even close to 1:1 magnification. He said that most images he took were simply impossible without VR.

Another really interesting point is that the AF was really fast with his D2Hs, fast enough in continuous AF-C to compensate for translational (subject to lens) motion !! Wow, if this holds true, I think Nikon has a real winner here :)

此君認為防震功能在近距離近到1:1的範圍還是有用的.

D200 and AF-S VR 105 Micro 2.8 G

A test I have made.

The lens is simply awesome ...

HI Matt, Vr is VR wether you are at long or close range. It is excellent but cannot produce miracles under1/20 sec. Remember that 105 becones around 160mm in FOV.

It focusses slowy for an AF-S lens, as expected by a macro lens.

Ok but VR effectiveness is dependent of the amplitude of the motion blur. The problem is that motion blur is proportionnal to the focal length of the lens AND inversely proportional to the distance camera-subject when the latter is small. Precisely:

motion blur amplitude = k*f(d+f)/d

where k is a constant, f is the focal length and d is the distance between the subject and the nodal point of the lens.

So the question is still unanswered. How does VR perform at 1:1 reproduction ratio?

I hate mathematicians ... :-)

What I meant is the Stabilisation doesn't vary whathever the focal distance is. I agree with what you are saying about amplitude and closeness of subject but the VR doesn't vary in effectiveness in relation to the focus lenght.

Unless I am wrong or I totally missed the point.


VR on a i:i, from actual testing is very very good, not worse than on longer f dist

Resalut Yves,


VR effectiveness is dependent of only one thing: motion blur amplitude, that is how far from the original position the subject is dancing on the sensor. So if you can get the subject to move the same at 1:1 than at 1:10 you'll get the same effectiveness from the VR. The problem is it is much harder to keep the image still on the sensor at 1:1 than at 1:10 (cf. my previous post). Another way of stating the previous formula is

motion blur amplitude = k* R / d

where k is a constant, R is the reproduction ratio and d the distance from the subject to the nodal point.

Moi j'aime bien les mathematiciens. ;-)

105 VR Nikkor is unbelievable!!!

I got this lens today in the morning when I was at work. I did some test shots, nothing special but I can’t believe what this lens can do! VR does work on macro! It is so sharp! I can’t say it enough it’s sharp! The colors are great the out of focus backgrounds are smooth and creamy.

This puts my 60 Micro out of business! Aside form document copy work I can’t see myself using the 60 any more.

It’s a big lens, much bigger then the older 105 and much sharper, the new 105 VR is something else.

All shots have the corresponding 100% crops

Hope this helps enjoy!

基本上Nikon VR Micro 105跟Micro 105價差可超過一支碳纖腳架的價格
微距攝影還是裝置腳架上來的穩定多了
VR2可降四級快門
腳架沒有快門級別限制

因此我到還慢建議買就版105
多餘的錢可以多入手一大型碳纖腳架
外帶一支桌上用中小型腳架^^

kenkuo2006  大大~

那是以微距攝影來說 (如 小虫 小花 靜態小品)

但如果用Nikon VR Micro 105 來拍 一些 大型動物 (如小貓小狗) /人像 / 建築/ 風景...等 一些
跳脫Micro  的體材 ~

那實際上會不會有用呢~  

小弟想這就是網路上前輩一直在討論VR 對於實際使用上的爭執點  
不知道是否跟小弟想的一不一樣 ~

各位前輩又覺得如何呢 ?

NIKON 105mm f/2.8 AF-S VR LENS

I received this new lens on 27 March 2006. The lens is solidly built, is very easy to use and balances well on my D200. ALL PHOTOS WERE HANDHELD (some down to 1/10 second!).

做成 IF,和小黑五一樣,鏡頭完全不會伸縮。

對焦速度方面:
因為有 AF-S,所以當然對焦速度比以往的 micro 鏡頭還要快,
然後我以前有在 yodobashi-camera 的展示台上用過 Sigma 150mm Macro HSM
感覺上好像是比 Sigma 的 HSM 快一些。
然後也因為是 AF-S ,所以不僅對焦快,而且很安靜,還有全時手動對焦,這對於拍
Micro 上真的很方便。

VR:
當然對焦在無限遠時,就和一般的 105mm 的鏡頭一樣,
因此新的 VRII 絕對能發揮防手振的效果。
雖然官方網頁有寫隨著對焦距離的縮短(放大率上升)
VR效果可能不能100%保證有效,
當然另外一個原因就是,當放大率越高時,既使是手部的輕微一點震動,
因為放大倍率高,所以畫面震動的程度也是很高,
再加上如果拍攝的物品不是靜止物時,即使利用VR讓自己手持能很穩定的拍攝,
當被攝物體移動時,或是自己前後稍微有移動時(景深淺的情況下)
非常容易會讓焦點馬上就跑掉。
雖然這樣子說,不過還是測試一下在高放大倍率時,VRII到底有沒有效果。

風景照,星期三在漁人碼頭拍的






D200 + AFS VR Micro 105mm F2.8
上腳架 F11 1/20s ISO100 中央中點測光 手動對焦




另外這顆鏡頭的銳利度真的沒有話說,

順便放上這張的原圖,因為流量關係,大概會放個幾天吧。

D200的 機身設定,
Color => Mode I (sRGB)
階調對比 => 普通
色度 => +6度 (因為 D200內訂的設定的話,拍大紅色會紅到爆,所以這邊有修正)
彩度 => 普通
銳利化 => 稍微強 (因為 D200內訂的成像會比較軟一點,所以銳利化設定比普通多一級)
