Canon's DIGIC III processor delivers responsive operation, improved color rendering and near-instant start-up time.

Other additions on the Canon 40D include interchangeable focusing screens, an AF-ON button, the EOS Integrated Cleaning System for sensor dust reduction, rubber strips around the battery and CF doors for improved weather sealing and three new optional accessories: an IS version of the 18-55mm kit lens; a new backward-compatible, live view mode, and a weather-sealed battery grip.

This includes various shooting modes, ability to change ISO and white balance, a pop-up flash unit, an LCD screen of 3.0 inches (an upgrade from the previous model, the Canon EOS 30D with a screen of only 2.5 inches), and a rugged magnesium alloy protective inner-shell, which both the Canon 30D and 40D have.

The newest feature to the 40D is Live View (previously used on the EOS 20Da), allowing photographers to use the LCD screen as their viewfinder.
