Panasonic GH5 vs Pentax K-3 II Sensor Comparison

Often, it can be difficult to visualise the difference in sensor sizing only by checking out specs. The photograph below should provide you a better sense of the sensor measurements in the GH5 and K-3 II.

As you can plainly see, the 2 cameras enjoy different megapixels and different sensor sizing. The GH5 having a smaller sensor will make achieving shallower depth of field harder and the Pentax K-3 II will provide greater detail using its extra 4 Megapixels. Higher resolution can also make it easier to crop shots far more aggressively. The more modern GH5 is going to have an edge in sensor technology.
