Pentax K-3 II vs Sony RX100 V Sensor Comparison

Sometimes, it is very hard to envision the contrast between sensor sizes purely by reading specifications. The image here might offer you a much better sense of the sensor measurements in the K-3 II and RX100 V.

Plainly, each of the cameras posses different megapixel count and different sensor sizes. The K-3 II with its bigger sensor will make shooting bokeh less difficult and the Pentax K-3 II will deliver extra detail using its extra 4 Megapixels. Higher resolution will enable you to crop photographs somewhat more aggressively. The more aged K-3 II is going to be disadvantaged when it comes to sensor innovation.
