Till I’m able to get my hands on it the information from the press release:

The EOS 450D is designed to make photography a fluid experience for photographers of all levels and experience. Housed in a compact body that weighs less than 475 grams, the camera features an improved grip design that provides a natural, ergonomic fit with the user’s hands. A large, bright viewfinder makes image composition clearer and more comfortable. The menu system inherited from professional EOS cameras uses a simplified tab structure that does away with scrolling. It includes a user-defined My Menu tab for instant access to frequently used settings.

Several custom functions are available to optimise the quality of photos captured in a range of situations. Highlight Tone Priority boosts the dynamic range at the highlight end, providing better tonal detail from wedding dresses, cloudy skies and other bright objects. The new Auto Lighting Optimiser corrects brightness and contrast during image processing, while improving skin tones in portraits by ensuring correct exposure for faces. Photographers can also enable additional noise reduction for shots captured at high ISO speeds.

Available for the first time on a Canon consumer D-SLR, Live View mode makes it easier to shoot from awkward angles, such as ground-level macro shots or when shooting from a tripod. The image from the Live View mode is displayed as a smooth, 30fps video feed on the 3.0″ LCD, which is 50% brighter than the screen of the EOS 400D. A grid line display and live histogram can be selected to help with shot composition and exposure. While focusing, the photographer can zoom in on specific details with up to 10x magnification of the image displayed on the LCD screen. Two types of auto focus are available: Quick AF flips the camera mirror momentarily to engage the AF sensor; Live AF uses the image contrast data to focus – a method familiar to anyone upgrading from a compact digital camera.

For studio environments, remote Live View lets the photographer compose, adjust settings and capture the shot from a PC using the supplied EOS utility software.

The EOS 450D complements its headline features with a host of smaller improvements that enhance the photographic experience. The viewfinder now displays all key exposure information including ISO speed. The addition of spot metering (4% of viewfinder) allows for greater control over exposure in tricky lighting conditions. PictBridge functionality has been expanded so that photographers can correct horizons and add picture effects before printing. A new high capacity battery extends shooting time on a single charge to a maximum of 500 shots.
