Nikon Z5 vs Pentax K100D Sensor Comparison

Oftentimes, it is very difficult to visualise the difference in sensor measurements just by looking through a spec sheet. The graphic underneath may offer you a more clear sense of the sensor sizes in the Z5 and K100D.

Clearly, each of these cameras offer different megapixels and different sensor measurements. The Z5 because of its bigger sensor will make getting shallow depth of field simpler and the Nikon Z5 will provide you with greater detail as a result of its extra 18 Megapixels. Higher resolution can also let you crop shots a little more aggressively. The newer Z5 will have an edge with regard to sensor tech.
