Canon 20Da vs Pentax K-7 Sensor Comparison

More often than not, it's hard to picture the gap between sensor sizes merely by reviewing technical specs. The pic underneath will give you a more clear sense of the sensor sizing in the 20Da and K-7.

As you can tell, both the cameras provide the same sensor dimensions albeit different resolution. You can expect the Pentax K-7 to deliver extra detail using its extra 7 Megapixels. Higher resolution will let you crop photographs more aggressively. The more aged 20Da is going to be disadvantaged when it comes to sensor technology.
