The Canon EOS 40D is a 10.1-megapixel semi-professional digital single-lens reflex camera. It was initially announced on August 20, 2007 and was released at the end that month. It is the successor to the Canon EOS 30D and 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.
Improvements
Changes over the 30D include a higher-resolution sensor (10.1 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 written at a faster pace. Frames per second has been increased from 5 to 6.5.
The 40D uses a new format, Canon's sRAW, that it can write pictures to. The RAW format is 14-bit instead of the 12-bit of the 30D.[1].
The camera uses the new DiG!C III image processor, which was first used in the Canon EOS-1D Mark III, introduced earlier that year. A new sensor cleaning system has been introduced. It can also use the Canon Wireless File Transmitter WFT-E3/E3A.
Features
EOS 40D with EF-S 17-85 F/4-5.6 IS USM
The 40D has many similar characteristics to its predecessors the 20D and 30D. This includes various shooting modes, ability to change ISO and white balance, a pop-up flash unit, and an LCD screen. The LCD screen is much larger than the previous models (3.0" from 2.5" previously).
The 40D has more megapixels, and the resolution sizes are slightly higher than the 20D and 30D. Its RAW format is 14-bit.
A new feature is Live View, which allows photographers to use the LCD screen as the viewfinder. The shutter noise is quieter in this mode.
Firmware and software
Canon released its DPP 3.1 RAW converter alongside the 40D.
Initially, Adobe Lightroom did not have official support for the 40D though RAW and JPEGs from the camera did still work. Official support for the 40D as well as the 1Ds Mark III was added with Lightroom 1.3, available as a free update from Adobe.
