Pentax K-3 II vs Sony RX100 VA Sensor Comparison
Oftentimes, it is very tough to imagine the contrast between sensor sizing only by reviewing specifications. The visual underneath should give you a much better sense of the sensor sizing in the K-3 II and RX100 VA.
To sum up, both the cameras feature different megapixel count and different sensor sizing. The K-3 II using its larger sensor is going to make achieving shallow DOF less difficult and the Pentax K-3 II will deliver extra detail with its extra 4 Megapixels. Greater resolution will enable you to crop photos way more aggressively. The older K-3 II is going to be behind in sensor tech.
