Panasonic GX85 vs Pentax K-3 Sensor Comparison

Typically, it is tough to imagine the contrast between sensor dimensions purely by reading through technical specs. The pic here should give you a better sense of the sensor measurements in the GX85 and K-3.

As you can tell, both cameras posses different resolutions and different sensor dimensions. The GX85 having a tinier sensor is going to make shooting shallow depth of field more difficult and the Pentax K-3 will give extra detail because of its extra 8 Megapixels. Greater resolution will make it easier to crop pics somewhat more aggressively. The more recent GX85 provides an edge when it comes to sensor tech.
