Panasonic GX9 vs Pentax K-5 IIs Sensor Comparison

Quite often, it can be tough to imagine the contrast between sensor sizing purely by reading a spec sheet. The photograph here might offer you a much better sense of the sensor measurements in the GX9 and K-5 IIs.

As you can see, both of the cameras come with different megapixel count and different sensor sizing. The GX9 with its tinier sensor is going to make getting shallower depth of field more difficult and the Panasonic GX9 will deliver extra detail having an extra 4 Megapixels. Higher resolution will let you crop photographs a good deal more aggressively. The more modern GX9 should have an edge in sensor tech.
