 include a higher-resolution sensor (10.1 megapixel instead of 8.2). The sensor also has better noise control than previous models. The 40D has a larger memory buffer so more pictures can be taken in succession without a slow down in frame rate. Frames per second has been increased from 5 to 6.5.

The 40D adds a new format, Canon's sRAW, which is a smaller RAW image for smaller prints and reduced file sizes. The 40D's RAW format is 14-bit instead of the 12-bit of the 30D.

The camera uses the new DIGIC III image processor, which was first used in the Canon EOS-1D Mark III

, introduced earlier that year. Canon’s DIGIC III processor delivers responsive operation, improved color rendering and near-instant start-up time. A new sensor cleaning system has been introduced. It can also use the Canon Wireless File Transmitter WFT-E3/E3A.

The 40D has a larger screen (3", of the same resolution) than the 30D (2.5") and 20D (1.8"). There is also a new menu for external and internal flash control, including second curtain sync.

Other additions on the Canon 40D include interchangeable focusing screens, a much-needed 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

Overview and features

The 40D has many similar characteristics to its predecessors the 20D and 30D, but also many differences. 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 40D has more megapixels (10.1 MP as compared to 8.2 MP in 30D), and the resolution sizes are slightly higher than the 20D and 30D. Its RAW format is 14-bit.

The newest feature to the 40D is Live View (which the 30D, 20D, 10D, and all previous models do not have), allowing photographers to use the LCD screen as their viewfinder. It is very useful for taking pictures low to the ground, when your eye can't reach the viewfinder. The shutter noise is quieter in this mode, as well.
