Canon 10D vs Olympus E-3

On this page, we are contrasting the Canon 10D and Olympus E-3, both Advanced DSLR digital cameras by companies Canon and Olympus. There is a substantial difference between the sensor resolutions of the 10D (6MP) and E-3 (10MP) and the 10D (APS-C) and E-3 (Four Thirds) offer totally different sensor measurements.

Photography Glossary

The 10D was revealed 5 years prior to the E-3 and that is quite a big difference as far as tech is concerned. Both of these cameras have the same body design (Mid-size SLR).

Before going right into a in depth comparison, here is a brief introduction of how the 10D grades versus the E-3 in terms of portability, imaging, features and an overall grade.

Below is a sample of the gallery pics for Canon EOS 10D & Olympus E-3. The full galleries are available at Canon 10D Gallery & Olympus E-3 Gallery.

If you're going to lug around your camera, you will want to consider its weight and measurements. The Canon 10D enjoys outer dimensions of 150mm x 107mm x 75mm (5.9" x 4.2" x 3.0") and a weight of 875 grams (1.93 lbs) and the Olympus E-3 has proportions of 142mm x 116mm x 75mm (5.6" x 4.6" x 3.0") with a weight of 890 grams (1.96 lbs).

Keep in mind, the weight of an ILC will differ depending on the lens you are using at that time. Here is a front view over all size comparison of the 10D and the E-3.

Taking into consideration size and weight, the portability grade of the 10D and E-3 is 56 and 56 respectively.

Generally, its difficult to see the contrast between sensor measurements purely by going over a spec sheet. The visual below might give you a much better sense of the sensor dimensions in the 10D and E-3.

As you can see, both of these cameras provide different megapixel count and different sensor measurements. The 10D having a larger sensor will make achieving shallow DOF easier and the Olympus E-3 will offer extra detail because of its extra 4 Megapixels. Greater resolution can also help you crop images more aggressively. The older 10D is going to be disadvantaged with regard to sensor technology.
