The Canon EOS 40D is a 10.1-megapixel semi-professional digital single-lens reflex camera. It was initially announced on 20 August 2007 and was released at the end of that month. It is the successor of the Canon EOS 30D, and is succeeded by the EOS 50D. It can accept EF and EF-S lenses. Like its predecessor, it uses an APS-C sized image sensor, resulting in a 1.6x field of view crop factor.
Changes over the 30D 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 of 320 × 240 pixel = 76,800 pixels) than the 30D (2.5"). 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, 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.
