The Canon EOS 40D is the new Canon DSLR model that replaces the ever popular Canon EOS 30D. At the beginning of the EOS 40D provides for a somewhat subdued upgrade to a popular model, there are some interesting new features that create this a much better camera.
The new Canon EOS 40D comes with a 10-megapixel APS-C size CMOS sensor fitted and a new DIGIC III image processor. The same dust-reduction technology found on the> Canon EOS 400D / XTi, now has its way on the 40D. Other important improvements bring the 40D and closer to the flagship Canon EOS-1D series. The menu system now uses the same paging system as 1D and 1Ds more expensive siblings. The 40D now supports both RAW and sRAW image formats, along with a change from the previous 12-bit to an impressive 14-bit RAW format. This is all possible through the use of a single DIGIC III processor, the sameprocessor now being used on the EOS 1D. Improvements in the auto-focus system include cross-type AF points for F5.6 or faster EF and EF-S series lenses. A larger, brighter viewfinder is included in the update, along with the ability to chose from several different focusing screens. Following in the footsteps of the EOS 1D, the 40D features a larger 3-inch LCD which finally has Live-View. The frame rate is also improved to 6.5 fps although this was not always obtainable in performance tests.
One of the first things we noticed was ergonomics of this particular camera. It just feels "good" in the hand. For a prior XTi/XSI user upgrading from the Rebel models, you would gain an imediate improvement to the cramped feeling of the Rebels. The build quality is superior, and Canon has finally seen fit to include weather sealing around the battery compartment doors. Another thing you notice is the sound of the shutter. Much quieter than in previous XXD Models. One of the features allowed the inclusion of the current ISO setting in viewfinder and top LCD. It looks like Canon finally listened to those that function.
The EOS 40D takes surprisingly well in performance tests. The 10-megapixel CMOS sensor in combination with the new DIGIC III image processor is an ideal system. In tests at the side of the Canon EOS 30D and a competitive model such as the Nikon D200, an extension of theCamera dynamic range is easily recognized, especially in the shadows. RAW images are typically very sharp right from the camera. Canon cameras a reputation for its noise-free images and do not provide the 40D in the lurch. Both ISO 1600 and ISO 3200 images were relatively quiet, and were certainly appropriate for most situations. There is a new noise reduction option available to remove the color noise.
The EOS 40D is compatible with all accounts, a very nice DSLR anda worthy successor to the EOS 30D.
