Improvements

Changes over the 20D include a bigger LCD rear screen, improved shutter mechanism rated for 100,000 actuations, improved frame capacity, 1/3 stop increments for sensor speed and an added spot meter. This unit retains the same sensor as its predecessor; all lenses still have an

Resolution

The Canon EOS 30D has several resolution settings: * Raw CR2 format (3504 x 2336) * Large/Fine (3504 x 2336) * Large/Normal (3504 x 2336) * Middle/Fine (2544 x 1696) * Middle/Normal (2544 x 1696) * Small/Fine (1728 x 1152) * Small/Normal (1728 x 1152) * (There are also six resolution settings for JPEG+Raw which are the same as the first six but which also attach a Raw file in a separate .cr2 file).

Features

The Canon EOS 30D features a Mode Dial on the top which selects the shooting mode. It is divided into two sections: ''Creative Zone'' and ''Basic Zone''. The Creative zone provides manual and semi-manual modes; it gives access to RAW format, manual exposure,

The camera features (like many others) two LCDs, one monochrome at the top, which contains all information pertinent to shooting, and a full-color one at the back, which is used for picture reviewing and menu navigation. The rear display has a resolution of 320 × 240 pixel (76,800 pixels).Canon counts the sub-pixels of each pixel, i.e. the red, green, and blue channel of each pixel, and therefore specifies the rear display to have 76,800 × 3 = 230,400 or ca. 230,000 dots. The Canon EOS 30D also features a large dial on its back which is used for fast scrolling over the stored pictures or over the settings in the menu. The JUMP button can also be used to reach sections of the menu easily, as well as scroll through either 10 or 100 image in playback mode. The 8 way controller above the dial is used to select one of the 9 AF points, to move around a zoomed image in playback mode, and to set custom white balance. Its internal
