Olympus 1 vs Pentax K100D Sensor Comparison

All in all, each of these cameras provide different resolutions and different sensor sizes. The 1 featuring a smaller sensor is going to make shooting shallower depth of field more difficult and the Olympus 1 will show more detail utilizing its extra 6 Megapixels. Higher resolution will also allow you to crop photographs more aggressively. The younger 1 should have an edge in sensor innovation.
