Pentax K-1 II vs Pentax K20D Sensor Comparison

Sometimes, it is tough to picture the contrast between sensor measurements just by reviewing specifications. The photograph below should offer you a far better sense of the sensor sizing in the K-1 II and K20D.

Plainly, the 2 cameras posses different resolutions and different sensor measurements. The K-1 II due to its bigger sensor is going to make achieving shallower depth of field simpler and the Pentax K-1 II will deliver more detail due to its extra 21MP. Higher resolution will also enable you to crop shots somewhat more aggressively. The more recent K-1 II should have a benefit with regard to sensor tech.
