Canon 6D vs Pentax K-3 II Sensor Comparison

Often, its difficult to imagine the difference between sensor sizing merely by reading through technical specs. The photograph here may offer you a more clear sense of the sensor measurements in the 6D and K-3 II.

As you have seen, each of these cameras enjoy different megapixels and different sensor sizing. The 6D using its bigger sensor is going to make achieving shallower DOF simpler and the Pentax K-3 II will give you greater detail using its extra 4MP. Higher resolution will allow you to crop photographs far more aggressively. The older 6D is going to be disadvantaged with regard to sensor innovation.
