Olympus TG-310 vs Pentax Q-S1 Sensor Comparison

Often, it's hard to picture the gap between sensor dimensions purely by reading technical specs. The picture here will give you a greater sense of the sensor measurements in the TG-310 and Q-S1.

As you have seen, both of those cameras enjoy different megapixel count and different sensor dimensions. The TG-310 having a tinier sensor is going to make shooting shallower depth of field harder and the Olympus TG-310 will offer you more detail having an extra 2MP. Greater resolution will enable you to crop pics far more aggressively. The more aged TG-310 is going to be behind in sensor innovation.
