Panasonic GH5S vs Pentax K-1 Sensor Comparison

Sometimes, it is very difficult to visualise the contrast between sensor sizing merely by checking technical specs. The photograph here might provide you a clearer sense of the sensor sizing in the GH5S and K-1.

As you have seen, both of the cameras come with different megapixels and different sensor sizing. The GH5S having a tinier sensor will make shooting shallower depth of field more challenging and the Pentax K-1 will give you greater detail with its extra 26 Megapixels. Higher resolution can also enable you to crop pictures a good deal more aggressively. The more recent GH5S will have a benefit with regard to sensor technology.
