30D 的那片 CM...(恕刪)
350D和20D的CMOS是不一樣的.
請參考http://www.dpreview.com/reviews/canoneos350d/
雖然,30D的變化不大,但改變的東西都是現有20D使用者所希望加強的.
如快門耐用度10萬次以上.

可能是以價格來打D2...(恕刪)
良心建議,如果這幾年要上FF機,還是買EF鏡,而不是EF-S鏡
EF-S鏡有兩大缺點: 1.價錢實在貴,2.只能用在APS-C上, 不能用在APS, APS-H跟底片機上
最好是30D價格可以壓過D200...不然就等著D200稱霸APS-C...
Nikon在APS-C上著力還是比Canon有誠意
ps:點測只能中央,不能隨對焦點連動...跟5D一樣
20D, 1VHS, 3, 5D, 17-55, 16-35II, 85L, 35L, 小白IS, V125/2.5Macro, 550, 580
New features / changes compared to the EOS 20D
* Redesigned body (more EOS 5D like)
* Larger LCD monitor (2.5")
* Soft-touch shutter release button
* AE/AF lock remains set if shutter is kept half-pressed between shots
* Faster startup and wake from sleep times
* Direct print button on rear of camera (woo!)
* Spot metering
* 100,000 shot shutter cycle
* ISO selectable in third stop steps
* ISO speed shown in viewfinder as you change it (still not once changed though)
* Selectable 5 or 3 fps continuous shooting
* PictureStyles instead of simple image parameters
* 9,999 images per folder (instead of 100 as per the EOS 20D)
* 15 menu languages (3 new) -- 繁體中文也有了!
此外我也看到20D上市時要1499USD, 現在30D降為1399USD.
同時也附上DP Review D20 測試報告的結論, 讓你看看D30改進了多少!
Conclusion - Pros
* Excellent resolution, a match for the EOS-1D Mark II
* Good color, virtually identical response to the EOS 10D, lighter overall tone
* Now trademark Canon CMOS noise free 'silky smooth' images
* Very low noise levels even at high sensitivities, fully usable ISO range (100 - 3200)
* Excellent long exposure capability, better with noise reduction on (some black pits)
* Near-instant power on time, more responsive overall, reduced write times
* Five frames per second continuous shooting, up to 23 JPEG in a burst
* Another step improvement in auto focus, 9 point, noticeably faster, better in low light
* Dual-purpose buffering means there's always space for the next shot
* Good metering, but still no specific 'spot metering'
* In-camera programmable 'parameter sets' to control image processing algorithms
* Selectable color space (sRGB / Adobe RGB)
* Now supports new smaller EF-S 'digital' lenses
* Very solid body build, feels extremely robust, almost a 'baby EOS-1D'
* Built as a Digital SLR from the ground up
* Much less of a 'dust problem' than CCD-based digital SLRs
* Remote capture software for studio setups
* Playback magnification up to 10x (perfect for checking focus), easier panning (joystick)
* Excellent battery life, light weight and small batteries (now more powerful)
* Very good supplied software suite (EVU, DPP, Remote Capture and Elements)
* Higher pop-up built-in flash, should make red-eye less of a problem
* E-TTL II flash metering, includes distance information from lens
* USB 2.0 Hi-speed connectivity
Conclusion - Cons
* Opening the CF compartment door shuts camera down, loses any buffered images
* Average automatic white balance performance, still very poor under incandescent light
* PowerShot-like sharpening algorithm (same as EOS 10D) could be improved
* Not a major leap forward in output size, this is not a reason for 10D owners to upgrade
* No spot metering
* Louder shutter release noise
* Can't adjust continuous shooting frame rate (always 5 fps)
* Flash sync 1/250 sec (compared to 1/500 sec for the Nikon D70)
* Confusing sequence of lights in AI Servo auto focus
* Still only five levels of adjustment for image parameters, should be more flexible
* Only 1.8" LCD monitor (time for a high resolution 2.0" I would think)
* ISO sensitivity not displayed on viewfinder status bar while being changed
