Canon 20D vs Canon 6D MII Sensor Comparison

Often, it is hard to envision the gap in sensor measurements purely by researching a spec sheet. The visual here will provide you a stronger sense of the sensor dimensions in the 20D and 6D MII.

As you can see, each of these cameras offer different megapixel count and different sensor measurements. The 20D because of its smaller sensor will make achieving shallow depth of field more difficult and the Canon 6D MII will provide you with extra detail having its extra 18MP. Greater resolution will enable you to crop photos a little more aggressively. The older 20D will be behind in sensor technology.
