各位 NIKON 相機達人你們好
先跟你們說聲抱歉這類的文章恐怕層出不窮
只不過小弟身邊真的沒有人懂
又有一些比較深入的問題想問...
小弟最近入手了一台D3000(還沒收到..)
在大部分中文網站
大部分都是毫不考慮的推薦了比較新款的D3000
不過 卻在國外的網站
幾乎一面倒的覺得D40比D3000值得購買(價錢也是因素之一 不過我們這邊暫不討論)
以下是我做了非常多調查之後發現的
因為小弟這方面的英文不是很懂
加上剛剛進入單眼的行列
把一些調查到的資訊加上自己的看法跟大家交流一下
還希望各位達人們給點意見
謝謝
d3000之餘D40的重點優勢
---對焦點多---
11點對焦Vs D40的三點對焦
對於動態的捕捉很有幫助
雖然三點對焦可以半按快門再移動重新構圖
不過 如果拍的是移動中的物體就沒有辦法了
不過11點對焦真的有這麼重要嗎?
因為我沒有很多拍照的經驗
希望各位達人們可以分享一下差別所在

D40之餘D3000的重點優勢
---高iSO表現優良---
以及
---內閃的快門支援到 1/500---
這裡我需要引用一段英文的文章
Shutter. Yet another change carried over from the D40x design relates to the Nikon D3000's x-sync speed (flash sync, or the fastest shutter speed you can use while the flash is active) of 1/200 second, down from the D40's 1/500 flash sync speed. The reason for this difference is that the D40 had a relatively slow mechanical shutter, but "gated" the CCD for its shortest shutter speeds. This meant that the CCD itself was actually exposed to incoming light for a longer period of time (perhaps 1/100 - 1/200 second), but the camera manipulated the chip's control voltages to only allow light collection for a much shorter period of time. This made it easy to produce very brief exposures without the expense of a really high-speed mechanical shutter, and as a consequence also permitted very high x-sync speeds.
There's no such thing as a free lunch, though, and the downside was that large light overloads could cause streaking or smearing in the D40's images. The good news is that the Nikon D3000 won't suffer from these problems, unlike the D40 -- but the x-sync speed is slower as a result.
這邊有解釋為甚麼X-Sync的速度限制從D40的1/500 到現在的 1/200
小弟英文不好 加上這方面的學識疏淺
我想大概是說 D40 在X-Sync上面的優勢 反而造成他在逆光拍攝的劣勢
(因為光進來多少的關係….我也不是很懂…可以請達人們解釋一下嗎?)
另外 這個光進來比較多的D40 (不確定是不是這個原因)?
也因此在光暗的地方使用高ISO會表現的比D3000好
(網路上面的評比都是 D40的高Iso勝過 D3000一大堆….orz)

請各位達人為小弟解惑一下
謝謝

I also don't fully agree with the claims of the D40's better high ISO performance. Yes, you can see more noise in a D3000's high ISO photo. (Tip: try it with D-Lighting turned off.) But there are more pixels in the D3000's shot. More pixels, but each one not individually as good. More noise, but more signal as well. Is the D40's shot going to look better printed? I have very strong doubts, and this isn't something you can judge by looking at 100% crops on the screen. Add to that, that you can take advantage of the D3000's VR kit lens to shoot at a lower ISO in many circumstances.

大致上是說高ISO的表現好(d40) 可是 像素低
不見得在輸出的時候會贏 高ISO表現比較不好(d3000) 可是像素高的相機
