Olympus VG-145 vs Pentax Q-S1 Sensor Comparison

More often than not, its tough to see the difference between sensor measurements simply by reading technical specs. The graphic here will provide you a more clear sense of the sensor sizes in the VG-145 and Q-S1.

As you have seen, each of these cameras feature different megapixels and different sensor measurements. The VG-145 due to its tinier sensor will make getting shallower depth of field harder and the Olympus VG-145 will deliver more detail as a result of its extra 2 Megapixels. Greater resolution will also allow you to crop photos way more aggressively. The older VG-145 is going to be disadvantaged when it comes to sensor innovation.
