Panasonic S3 vs Pentax K-70 Sensor Comparison

Usually, it is very tough to visualize the gap between sensor sizes just by reading specifications. The pic here might give you a clearer sense of the sensor dimensions in the S3 and K-70.

Plainly, both the cameras come with different megapixel count and different sensor sizes. The S3 having a tinier sensor is going to make shooting shallow DOF more difficult and the Pentax K-70 will offer greater detail with its extra 10 Megapixels. Higher resolution will also make it easier to crop pictures a good deal more aggressively. The more aged S3 is going to be behind when it comes to sensor innovation.
