The Canon EOS 40D is the newest addition to Canon's extensive range of digital SLR cameras. Canon splits its DSLRs into three separate ranges, identified by the number of digits in the model name. The EOS 400D is the 'amateur' model, the EOS 1D and 1Ds are the 'pro' models, but in between is a series of semi-pro SLRs which are designed to appeal to keen enthusiasts, combining more advanced features and better build quality than the amateur models but without the expense of the pro cameras. The Canon EOS 40D is the latest of these semi-pro models, following on from the 8 megapixel 30D. It's not before time, either, because Canon's beginner-orientated EOS 400D has been out for some time now and, during that time, the more expensive 30D has had a lower resolution sensor. The 10-megapixel sensor in the new EOS 40D puts that right, and as well as being more robust and better-made than the 400D, it offers a number of other significant advantages. These include the ability to shoot at 6.5 frames per second, and a new Live View mode which enables you to compose shots directly on the bigger 3.0-inch LCD. Canon also claims to have improved the sensor design and incorporated its latest DIGIC III processing system to improve the image quality.
The Canon EOS 40D is more expensive than most entry-level digital SLRs, but this is reflected in its build quality. Where cheaper cameras use plastics, the 40D has a magnesium alloy body which should make it more durable in the long term. The finish seems tough and resilient too, and the memory card and battery doors are dust and moisture resistant, making the 40D potentially better suited to hostile environments, whether they're encountered on a photo shoot in the Himalayas or a trip to the seaside.
