The 40D was manufactured 17 months prior to the E-30 which makes them a generation apart from each other. The two cameras feature the same body design (Mid-size SLR).

Before diving right into a in depth comparison, here is a simple highlight of how the 40D matches up versus the E-30 in terms of portability, imaging, features and an overall rating.

Following is a preview of the gallery images for Canon EOS 40D and Olympus E-30. The entire galleries are available at Canon 40D Gallery and Olympus E-30 Gallery.

If you are intending to carry your camera regularly, you are going to need to factor in its weight and dimensions.

In many cases, it is very tough to see the gap between sensor sizing only by going over a spec sheet. The visual underneath will provide you a greater sense of the sensor sizes in the 40D and E-30.

As you can see, each of the cameras come with different resolutions and different sensor sizing. The 40D due to its bigger sensor will make getting shallow DOF simpler and the Olympus E-30 will offer you greater detail due to its extra 2 Megapixels. Higher resolution will make it easier to crop photographs a good deal more aggressively. The older 40D is going to be behind in sensor technology.
