點解Nikon連CoolPix 5700都係用補色CCD,而唔似其他牌子用原色CCD呢??
係咪因為咁,所以少人用Nikon數碼相機呢?

[yuppi]

仲要由D100先開始用原色CCD...............

May be simply because every manufacturer has its own preference.
Nikon used to use sony's CYMK filter CCD, but sony is going to discontinue this line, so nikon was forced to change to RGB CCD.

[yuppi]

How about Canon??
At past, Canon and Nikon both use same SONY 補色CCD.
After S100, you can see now all Cannon 用原色CCD.
But Nikon 要D100先用原色CCD...............
Why???

[yuppi]

It make me don't like Nikon數碼相機.
But I like Nikon相機.

[cfkw]

can you elaborate a bit more? Is CYMK/RGB that important?
It s a question, not a challenge.

所謂原色GRGB及補色CMYG CCD其實在很多報導不同文章綱站中分作過分析.兩者間實互有優點缺點.不能肯定何者為佳何者為劣.

以下引用一些評論文章.
原色CCD的優勢在於，畫質銳利，色彩真實，但缺點則是雜訊問題。因此，一般採用原色CCD的數位相機，在ISO感光度上多半不可超過400。
相對的補色CCD多了一個 Y 黃色濾色器，在色彩的分辨上比較仔細，但卻犧牲了部分影像解析度，而在ISO值上，補色CCD可以容忍較高的感度，一般都可設定到 800或以上。

至於綱友提到CYMK則並不等同於補色CMYG .正確應為CMYK分別是C Cyan. M Magenta. Y Yellow.K Key四個印刷原色.其實與CCD並沒有直接關係.

Thanks.

Oh sorry, I have mistaken CYGM with CYMK.

Anyway I don't think CYGM filter is necessarily bad, n fact CP5700's color is superior to many other DCs using RGB filter array.

其實我的問題係點解Nikon貴價機先用原色CCD(D100),但CoolPix 5700都係用補色CCD??

[trent]

Hmm...
In fact Nikon's D-SLRs used APS sized CCD, may be CCD of such size is available in RGB only.

[yuppi]

I see, thanks a lot.

[trent]

Sony's line of CYMG CCD is up to 5MP at 2/3", and it was used in CP5x00.

And seems nikon soon need to introduce another model for prosumer market to replace 5000/5700 before sony ceases production.
Or anyone think Nikon will adapt a RGB CCD on 5x00?

Personally speaking,

I don't care what it use, I just care the pictures quality.
