Canon EOS 40D digital SLR: First impressions
An SLR (or Single-Lens Reflex) camera is the most complex type of digital camera on the market, providing the most options and control, while producing the highest quality images. As the SLR market has become increasingly competitive, manufacturers continue to expand the feature sets on their SLRs to make them even more powerful, more versatile, and easier to use.
This is just what Canon has done with the 10-megapixel Canon EOS 40D digital SLR (Click on image at right), which runs about $1300 (body only) or about $200 more with a 28-135mm kit zoom lens.
In Canon's product line, the EOS 40D is what you might call a step-up SLR. At first glance, it may seem that there's not much difference between the 40D and Canon’s entry-level, inexpensive ($600, body only), 10-megapixel Canon Rebel XTi. However, aside from sharing the same type of CMOS sensor and including Canon's dust-cleaning system, the cameras are very different. (Canon has two ways to help minimize dust on the sensor: a hardware-based element that the company claims shakes off dust automatically with ultrasonic vibrations, and a firmware/software feature, called Dust Delete Data. Both are used to help avoid dust spots from appearing on images due to any minuscule particles that land on the 40D's CMOS sensor.)
