Pentax K-1 vs Pentax K-3 Sensor Comparison

Sometimes, it can be hard to visualise the difference between sensor dimensions only by going over a spec sheet. The image below may offer you a far better sense of the sensor dimensions in the K-1 and K-3.

Clearly, both cameras feature different megapixel count and different sensor dimensions. The K-1 having a larger sensor will make achieving shallow DOF easier and the Pentax K-1 will offer you extra detail with its extra 12 Megapixels. Greater resolution will allow you to crop photos way more aggressively. The fresher K-1 will have an edge with regard to sensor tech.
