一如大家所料，Canon 於 PMA 前宣佈推出 EOS 400D 的後繼型號 EOS 450D。外觀上 450D 跟 400D 的分別算是輕微，最明顯是用上 3 吋大型 LCD 以及較接近中階機的手柄包裹物料。規格上 EOS 450D 卻相當進取，除了內置支援即時對焦的 Live View 功能外，更配備 1220 萬像素 CMOS、DIGIC III 處理器、14-bit RAW、9 點 AF、4% 重點測光、3.5 fps 連拍等等，可謂相當之吸引。

以往 Canon 入門機一向不設重點測光，上一代的 EOS 400D 最精細的測光模式就只有局部測光，測光部分佔畫面中央約 9%。今次 EOS 450D 提供重點測光可說是一個突破，提供 4% 的重點測光，跟 EOS 40D 的 3.5% 已經相差不遠。

除此以外，EOS 450D 亦是近期第一部加入 Live View 功能的入門單反。在 Live View 模式時，除了可以使用傳統的 AF 感應器對焦之外，同時更提供 Live AF 模式，利用 DC 對焦的原理進行即時對焦，避免對焦時畫面出現遮黑的情況。LCD 增大至 3 吋，像素同樣為 230,000，光度比 EOS 400D 提高了 30%。

影像規格方面，除了像素上的提升，EOS 450D 亦提供更多的方案以增加影處的層次。EOS 450D 支援 14-bit 影像處埋以及 RAW 儲存，令相片漸變更為順暢。此外，高光先決（Highlight Tone Priority）以及自動光度優化（Auto Lighting Optimiser）功能亦令相片的光暗位層次更加明顯，對比更為自然。

另一方面，EOS 450D 首次採用了全新型號 LP-E5 鋰電池，容量比以往的 NB-2LH 增加一半，令拍攝壽命可以增加至 500 張。配合新電池的使用，今次 Canon 亦為 EOS 450D 推出新型號電池手柄 BG-E5，直度拍攝更加得心應手。

EOS 450D 機身定價約為 $799 美元，連 EF-S 18-55mm f/3.5-5.6 IS 鏡頭的套裝定價約為 $899 美元。

Canon EOS 450D 主要規格︰

配備 12.2 百萬像素 APS-C 片幅 CMOS 感光元件。
3.5 fps 連拍速度，可拍攝 53 張 JPEG 或 6 張 RAW。
內置 EOS 綜合除塵系統。
提供 9 點自動對焦，中央點為 f/2.8 十字型 AF 感應器。
內置 DIGIC III 處理器。
設有 3 吋 LCD，提供 Live View 功能。
提供 4% 重點測光。
14-bit 影像處理。
ISO 100 - 1600 感光度。
0.1 秒起動。
取景器放大率為 0.87 倍。
支援 Picture Style 相片風格。

之前一直都覺得在入門版方面，
D80 無論在什麼角度都比起 400D 好得多，
今次 450D 的出現至少能夠搶回了入門版市場，
現在要看看 Nikon 怎樣應對。

Good price wor.

Ching, could you think that the price of MarkIII N should adjust a bit?

What do you mean Mark 3 N ?
Canon current have 1Ds Mark 3 and 1D Mark 3 available in current market.

1Ds Mark 3 flagship camera price at around HK$56K
( Just release not long ago, I don't think Canon will adjust price so soon )

1D Mark 3 price at around HK$31K
( Maybe you should consider this instead, built quality the same as 1Ds Mark 3 but cost less. )

Hope this help.

才買了400D
唉
450D 都幾正

How is it?

不知道台幣要多少錢~@@

Not expensive (relatively speaking).

I just bought the 40D.....
Hope the extra features on the 40D can justify the diff in price of US$350.

ISO 3200
Faster AF
Better build
Faster fps
More custom functions??
Better noise management??

Cons/Pros?
2Mp Less!

捧場，不錯，我喜歡阿，介紹再多一點就更好了

How was performance?

我好想買丫..不過真係好$$..

My 40D??

The main reason I switched from 300D to 40D is for focusing and noise control.  Both 17-55 IS and 70-200 f/4 IS perform a lot better on the 40D body.  AF is a lot faster and more accurate.  Noise management is better on the 40D as well, but of course not as good as the 5D!  If you expose the picture well, then noise is very much under control on the 40D.  I just got two faster primes, Sigma 30 1.4 and Canon 85 1.8.  See if they can do well on 40D la.  Going FF was what I was considering before I bought the 40D, but a crop body gives me more reach right now.  I spent the USD$800 difference on lenses instead.  

Thanks for expert opinion/comments.

CCD螢幕增為3inch很不錯，可是單眼相機以live view來構圖總覺得怪怪

What is "live view"?

14bit good
better than D60

How much?  When avaliable in HK?  Where is cheapest?

Upstairs shop.

400d 同 450d有 +- $2000

Which one do u prefer?

1000D would be a better choice for newcomers.
Certainly technology much better than 400D.
Also cost less than 400D as well.

450D in the other hand a bit expensive.
I rather buy 40D instead.
Any comments are welcome.

1000D is suitable for beginners and easy to use?
