Canon 20D vs Olympus E-30

Let's look more closely at the Canon 20D and Olympus E-30, both Advanced DSLR digital cameras by rivals Canon and Olympus. There exists a significant gap between the image resolutions of the 20D (8MP) and E-30 (12MP) and the 20D (APS-C) and E-30 (Four Thirds) have totally different sensor dimensions.

The 20D was manufactured 5 years before the E-30 which is quite a sizable gap as far as technology is concerned. Both of these cameras have the same body design (Mid-size SLR).

Before we go straight to a more detailed comparison, here is a simple view of how the 20D grades against the E-30 when it comes to portability, imaging, features and an overall mark.

This is a sample of the gallery pics for Canon EOS 20D and Olympus E-30. The entire galleries are viewable at Canon 20D Gallery and Olympus E-30 Gallery.

For anybody who is looking to travel with your camera often, you are going to need to consider its weight and size. The Canon 20D has got physical measurements of 144mm x 106mm x 72mm (5.7" x 4.2" x 2.8") along with a weight of 770 grams (1.70 lbs) while the Olympus E-30 has specifications of 142mm x 108mm x 75mm (5.6" x 4.3" x 3.0") having a weight of 695 grams (1.53 lbs).

Remember, the weight of an Interchangeable Lens Camera will vary dependant on the lens you use at the time. The following is a front view size comparison of the 20D versus the E-30.

Taking into consideration dimensions and weight, the portability grade of the 20D and E-30 is 59 and 60 respectively.

Quite often, it is hard to envision the contrast between sensor dimensions purely by reviewing a spec sheet. The pic below should provide you a clearer sense of the sensor sizing in the 20D and E-30.

As you can see, both of the cameras have different megapixel count and different sensor dimensions. The 20D due to its larger sensor will make shooting shallower DOF easier and the Olympus E-30 will offer you more detail due to its extra 4MP. Greater resolution can also let you crop pics a bit more aggressively. The more aged 20D is going to be behind in sensor technology.
