佳能今天宣布新一代的中端DSLR EOS30D，做为20D的升级换代产品，这个相机能带给我们什么惊喜呢，从Spec上似乎改进不大啊，无怪乎无忌上的C家的粉丝失望透顶，而N家的粉丝喜笑颜开，呵呵。。让我们仔细看看有什么改变吧。。
新增加功能：
* A new 2.5-inch, 230,000 pixel rear LCD monitor with wide viewing angle
* Canon's more flexible Picture Style menu, which replaces the Parameters menu of the 20D
* Sharpening of in-camera JPEGs can be turned off, which is a first for a Canon entry-level or midrange digital SLR
* ISO 100-1600 is now selectable in 1/3 stop increments
* ISO can be set without taking one's eye away from the viewfinder
* Increased burst depth: 11 frames for RAW CR2 shooting, 30 for Large Fine JPEG and 9 for RAW+JPEG
* A more-durable shutter that's rated for 100,000 cycles
* A slightly-shortened mirror blackout time of 110ms; Canon's specification for shutter lag remains the same as the 20D at 65ms
* Viewfinder information now includes a dedicated Flash Exposure Lock (FEL) indicator
* Switchable High-Speed Continuous (5 fps) and Low-Speed Continuous (3 fps) frame rate settings are now included
* An Auto setting in the Long Exposure Noise Reduction Custom Function
* The ability, like several more-pricey Canon digital SLRs, to simultaneously apply long exposure noise processing to one picture while capturing another
* The addition of a 3.5% spot metering mode
* 0.15 second camera startup time
* A more-precise 4-increment battery charge indicator
* Reduced energy compensation, for a promised improvement of 10% more frames per charge
* No more new folders created every 100 photos; in the 30D, a folder can hold 9999 photos
* A new automatic rotation option that enables verticals to not be rotated on the rear display but appear rotated in compatible browser software on the computer
* The ability to zoom in on a photo in Quick Review mode
* During playback, the image+shooting data screen will display either an RGB or Brightness histogram, file size and will optionally display AF markings
* Improved Jump function
* Refined multicontroller operation
* More-detailed error code information, which now appears on the rear LCD monitor (in addition to the top LCD panel); the camera settings information screen will also display Images Failed to Transfer when the WFT-E1/E1A is in use and a transmit error occurs
* More ways to wake the camera up from an Auto Power Off snooze
* Direct image transfer from the camera to a computer using the PTP protocol
* A revamped software package that includes Digital Photo Professional (DPP) 2.1, EOS Utility 1.0 (a new image transfer, camera settings and camera control application), Image Browser 5.6 (Mac) and ZoomBrowser EX 5.6 (Windows); DPP adds user-settable noise reduction and support for RAW files from the Canon EOS D2000 and D6000
* New and potentially useful direct printing capabilities (plus a dedicated direct print/image transfer button)
