Panasonic S1 vs Pentax 645D Sensor Comparison
Oftentimes, it can be difficult to picture the contrast between sensor measurements just by reviewing specifications. The photograph here will provide you a stronger sense of the sensor dimensions in the S1 and 645D.
Plainly, the 2 cameras offer different megapixel count and different sensor measurements. The S1 using its tinier sensor is going to make shooting bokeh more difficult and the Pentax 645D will offer you more detail having an extra 28MP. Higher resolution will also help you crop shots a little more aggressively. The fresher S1 should have an advantage in sensor innovation.
