Panasonic XS1 vs Pentax 645D Sensor Comparison

The XS1 using its tinier sensor is going to make achieving shallower depth of field tougher and the Pentax 645D will offer more detail having an extra 24 Megapixels. Greater resolution will make it easier to crop images way more aggressively. The newer XS1 provides a benefit when it comes to sensor innovation.
