Nikon Z6 II vs Pentax K-3 Sensor Comparison

In many cases, its tough to visualize the contrast in sensor measurements only by looking through specifications. The photograph underneath might provide you a much better sense of the sensor dimensions in the Z6 II and K-3.

Plainly, both of the cameras posses different resolutions and different sensor measurements. The Z6 II having a larger sensor is going to make shooting shallower depth of field easier and the Nikon Z6 II will result in greater detail with its extra 1 Megapixels. Greater resolution will let you crop pics somewhat more aggressively. The more modern Z6 II should have an advantage when it comes to sensor tech.
