![]() Tweaks can also be made to the ISO speed, exposure, colour space, white balance, bracketing and focal points through the menu. Finally, Program auto-exposure sets the shutter speed and aperture automatically, giving users the ability to shift both at once with the main adjustment dial. The Manual exposure mode lets you set both the aperture and shutter speed, while the Automatic depth-of-field uses the nine auto-focus points to ensure objects in the foreground and background are both in focus. Aperture-priority mode changes the depth of field allowing you to obtain softly blurred backgrounds or, alternatively, get everything in the frame into focus. There's also a quick start guide for eager beavers.įirst up in the "creative zone" is Shutter-priority mode, a setting that allows you to freeze the action in a shot or create a motion blur by leaving the shutter open for longer. The 179-page bundled instruction manual helps you get to grips with various settings and the layout of the camera, including its 20-odd array of buttons. Starting out, we stuck to the even-my-grandmother-could-use-this fully automatic setting, as we slowly waded into further settings, such as the 400D's user-selectable nine-point auto-focus system. The 400D is one step ahead, however, as it automatically cleans the sensor every time you switch it on or off - we like to imagine a teeny windscreen wiper system inside doing the job, but as the process is entirely hidden and automatic, we are unable to confirm this. We soon learned the knack of quickly swapping Canon's EOS lenses onto the body of the 400D to minimise the amount of time dust has to creep onto the camera's sensor. The main differences between the two models are an increase in resolution (up from 8 megapixels on the 350D to 10.1 megapixels on the 400D), improved auto focus (nine focal points on the 400D rather than the 350D's seven) and a larger, 2.5-inch LCD (up from the 300D's 1.8-inch screen). ![]() Canon's latest entry-level digital single-lens reflex (dSLR) camera, the EOS 400D (also known as the EOS Digital Rebel XTi), supersedes Canon's wildly popular 350D. ![]()
