Panasonic LX100 II vs Pentax K-S1 Sensor Comparison

More often than not, it is very hard to imagine the gap in sensor measurements only by researching technical specs. The visual here should give you a more clear sense of the sensor dimensions in the LX100 II and K-S1.

As you can tell, both cameras offer different megapixels and different sensor measurements. The LX100 II featuring a smaller sensor is going to make achieving shallow DOF more challenging and the Pentax K-S1 will provide you with extra detail due to its extra 3MP. Higher resolution can also let you crop pictures a little more aggressively. The younger LX100 II should have an edge in sensor technology.
