The new Canon EOS 40D is the successor model to the EOS 30D, which won market acclaim for its functionality and ease of use following its release in March 2006. Through the incorporation of state-of-the-art camera technologies, the EOS 40D offers high-level amateur users even more advanced functionality and responsiveness.

The EOS 40D combines a newly developed Canon proprietary APS-C-size (22.2 x 14.8 mm) CMOS sensor with approximately 10.1 million effective pixels and the high-performance DIGIC III image processor to deliver high resolution imaging performance and a rich tonal range. Offering users ISO speed settings ranging from 100 to 1600 and expandable to up to 3200, the model realizes low noise despite supporting high ISO sensitivity. In addition, the EOS 40D boasts a number of other innovations that significantly strengthen its core performance: high-speed continuous shooting of up to approximately 6.5 frames per second for up to 75 continuousframes in large/fine JPEG mode, high-precision all-point cross 9-point AF, and a newly designed viewfinder that provides improved visibility with an approximately 0.95x zoom ratio.

The Canon EOS 40D incorporates a range of advanced functions that offer levels of operability and ease of use approaching those of top-of-the-line digital SLR cameras. The Live View shooting function allows users to check images in real-time on the camera’s large 3.0-inch LCD monitor while shooting. The camera also enables users to change focusing screens, supporting a diverse range of shooting styles.

Moreover, the EOS Integrated Cleaning System sensor dust solution improves image quality not only with its Self Cleaning Sensor Unit, but also by collecting dust position data so that users can restore dust images even after photographing. The lightweight, high-rigidity magnesium alloy exterior and the shutter, durable for over 100,000 operations with maximum speed of 1/8000 second, further ensure a high degree of reliability.

The EOS 40D is compatible with Canon’s comprehensive range of EF interchangeable lenses, including the popular EF-S17-85mm f/4-5.6 IS USM, as well as the two new Canon EF-S-series Image Stabilizer-equipped lenses that were also launched today: the EF-S18-55mm f/3.5-5.6 IS standard zoom lens and the EF-S55-250mm f/4-5.6 IS telephoto lens.

Canon also announced today that concurrently with the EOS 40D it will release the Wireless File Transmitter WFT-E3, enabling users to transfer images to a server or computer via wireless or wired LAN. Offering USB hosting functions to connect to external media and a convenient vertically oriented grip, the WFT-E3 effectively fulfills a wide variety of photographic applications.
