Canon 20D vs Olympus E-510

Below is a extended assessment of the Canon 20D versus Olympus E-510, both Advanced DSLR cameras by competitors Canon and Olympus. The sensor resolution of the 20D (8MP) and the E-510 (10MP) is relatively comparable but the 20D (APS-C) and E-510 (Four Thirds) have totally different sensor sizing.

The 20D was manufactured 4 years prior to the E-510 and that is a fairly large difference as far as camera technology is concerned. Each of the cameras have the same body design (Mid-size SLR).

Before we go right into a in depth comparison, here is a brief overview of how the 20D scores versus the E-510 when considering portability, imaging, features and an overall grade.

Below is a preview of the gallery photos for Canon EOS 20D & Olympus E-510. The entire galleries are available at Canon 20D Gallery & Olympus E-510 Gallery.

For those who are aiming to lug around your camera regularly, you will want to consider its weight and dimensions. The Canon 20D comes with exterior dimensions of 144mm x 106mm x 72mm (5.7" x 4.2" x 2.8") with a weight of 770 grams (1.70 lbs) and the Olympus E-510 has dimensions of 136mm x 92mm x 68mm (5.4" x 3.6" x 2.7") accompanied by a weight of 490 grams (1.08 lbs).

Do not forget, the weight of an ILC will change depending on the lens you are utilizing at that moment. Underneath is a front view scale comparison of the 20D versus the E-510.

Taking into account dimensions and weight, the portability rating of the 20D and E-510 is 59 and 69 respectively.

Sometimes, it's tough to envision the gap in sensor measurements merely by going through a spec sheet. The graphic underneath will offer you a better sense of the sensor sizes in the 20D and E-510.

As you can see, both of those cameras provide different resolutions and different sensor measurements. The 20D featuring a bigger sensor will make achieving shallower DOF simpler and the Olympus E-510 will provide greater detail due to its extra 2MP. Higher resolution can also help you crop shots more aggressively. The older 20D will be disadvantaged with regard to sensor technology.
