Canon 6D vs Pentax K-3 II Overview
In this write-up, we will be reviewing the Canon 6D and Pentax K-3 II, both Advanced DSLR digital cameras by brands Canon and Pentax. The image resolution of the 6D (20MP) and the K-3 II (24MP) is relatively well matched but the 6D (Full frame) and K-3 II (APS-C) possess different sensor size.

The 6D was introduced 3 years prior to the K-3 II and that is quite a serious difference as far as tech is concerned. Both of these cameras offer the identical body type (Mid-size SLR).
Before we go in to a more detailed comparison, below is a brief highlight of how the 6D matches up versus the K-3 II in the way of portability, imaging, features and an overall rating.

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.
