Panasonic FS42 vs Pentax K-S1 Sensor Comparison

Typically, it's tough to envision the gap in sensor sizes just by looking through a spec sheet. The pic below might give you a better sense of the sensor measurements in the FS42 and K-S1.

Clearly, both cameras have different megapixels and different sensor sizes. The FS42 having a smaller sensor will make getting shallower DOF trickier and the Pentax K-S1 will provide you with greater detail having an extra 10MP. Greater resolution will allow you to crop pics a bit more aggressively. The more aged FS42 will be disadvantaged in sensor technology.
