The 20D was unveiled 2 years after the D100 which is quite a large gap as far as technology is concerned. Both of the cameras have the same body design (Mid-size SLR).

Before getting into a detailed comparison, here is a concise introduction of how the 20D matches up against the D100 when it comes to portability, imaging, features and an overall score.

Below is a sample of the gallery pictures for Canon EOS 20D and Nikon D100. The full galleries are provided at Canon 20D Gallery and Nikon D100 Gallery.

If you're going to carry around your camera regularly, you'll have to consider its weight and proportions.

Sometimes, it can be difficult to visualise the difference between sensor sizes only by going over specs. The image here will help offer you a much better sense of the sensor measurements in the 20D and D100.

As you can plainly see, the 2 cameras provide the same sensor dimensions but not the same resolution. You should anticipate the Canon 20D to offer you greater detail having an extra 2MP. Greater resolution will also allow you to crop images more aggressively. The younger 20D is going to have a benefit with regard to sensor innovation.
