The 40D is still a great pro-sumer camera, but it's been replaced by the Canon EOS 50D. We recommend buying that one. Here's what we had to say about the 40D when it was released in August 2007:

It's finally here! Canon's much talked about, much rumored 40D has arrived, and it's even better than you might have heard. A fine successor to the well-received 30D and 20D, the 40D brings the Canon EOS SLR line up to ten megapixels, brings the advanced DIGIC III image processor, and gussies itself up with a luxurious 3.0-inch LCD screen. Stay tuned to this page for more information as initial reports and reviews begin to roll in!

Canon Reviews

Top quality optics, dependability, and convenience of use are just some of the reasons that customers choose Canon digital cameras. One of the top makers of digital cameras in the world today, Canon has attained a reputation for creating some of the best digital cameras and digital SLRs available on the market. Canon cameras are inevitably on the camera wish list of any consumer that desires a high quality camera.

Canon is not generally a cheap brand by any means. In spite of this, Canon digital cameras have achieved the best buy status. This proves that you get great value for the extra money. In the past few years, Canon has begun releasing several types that are more inexpensive, without cutting quality.

Canon cameras come in two main types—the smallest is the Powershot line, compact, point-and-shoot cameras that still maintain a reasonable level of image quality. Canon Powershot cameras range from budget point-and-shoots like the ELPH 115 to an advanced compact with a 1.5” sensor, the G1X Mark II. Typically, if you are going to buy a point-and-shoot on nothing but the reputation of the brand, Canon is a pretty safe bet.

The second type of Canon camera is the EOS line—the DSLRs. The EOS line has a solid reputation as well for performance across the board, including video. Canon has a wide range of options available too, from top of the line full frame professional models to small, entry-level DSLRs.

While other manufacturers are concentrating on mirrorless models and packing more power into smaller cameras, Canon doesn't seem to be following that trend exactly. They've released some smaller DSLRs like the SL1, but haven't been putting time into mirrorless models. Whether this is good or bad is a matter of personal opinion, but the models that are out there are, more often than not, solid performers.
