Pentax K-S1 vs Pentax RS1500 Sensor Comparison
Usually, it is difficult to envision the contrast between sensor dimensions only by checking specs. The image here might give you a greater sense of the sensor measurements in the K-S1 and RS1500.
As you can plainly see, both the cameras provide different megapixel count and different sensor dimensions. The K-S1 featuring a bigger sensor will make shooting shallow depth of field easier and the Pentax K-S1 will give greater detail utilizing its extra 6 Megapixels. Higher resolution will also let you crop pictures more aggressively. The younger K-S1 is going to have a benefit when it comes to sensor innovation.
