Canon 20Da vs Canon 40D Overview
Following is a in-depth overview of the Canon 20Da and Canon 40D, both Advanced DSLR digital cameras and they are both sold by Canon. The sensor resolution of the 20Da (8MP) and the 40D (10MP) is pretty similar and they feature the same exact sensor measurements (APS-C).

The 20Da was announced 3 years prior to the 40D which is quite a serious difference as far as tech is concerned. Both cameras offer the identical body type (Mid-size SLR).
Before getting through a complete comparison, below is a short view of how the 20Da grades against the 40D for portability, imaging, features and an overall score.

Canon 20Da vs Canon 40D Sensor Comparison
In many cases, it can be difficult to visualise the contrast between sensor sizes merely by reviewing specs. The picture below will help provide you a better sense of the sensor sizes in the 20Da and 40D.
As you can plainly see, both the cameras enjoy the same exact sensor sizing albeit not the same megapixels. You can expect the Canon 40D to offer you greater detail with its extra 2 Megapixels. Higher resolution will also let you crop photographs far more aggressively. The more aged 20Da is going to be behind when it comes to sensor tech.
