Canon 20Da vs Sony A850 Sensor Comparison

More often than not, it is difficult to see the difference between sensor measurements simply by reading through technical specs. The graphic underneath should offer you a far better sense of the sensor sizes in the 20Da and A850.

As you can tell, each of these cameras have different megapixel count and different sensor measurements. The 20Da having a tinier sensor will make getting bokeh more difficult and the Sony A850 will resolve more detail with its extra 17MP. Higher resolution can also allow you to crop photographs a bit more aggressively. The older 20Da is going to be behind when it comes to sensor innovation.
