Olympus TG-3 vs Sony RX100 IV

Below is a in-depth overview of the Olympus TG-3 and Sony RX100 IV, former being a Waterproof while the other is a Large Sensor Compact by competitors Olympus and Sony. The image resolution of the TG-3 (16MP) and the RX100 IV (20MP) is very comparable but the TG-3 (1/2.3") and RX100 IV (1") provide totally different sensor size.

Often, its difficult to see the gap in sensor measurements simply by going through technical specs. The visual underneath should offer you a stronger sense of the sensor measurements in the TG-3 and RX100 IV.

As you can tell, both the cameras come with different megapixel count and different sensor measurements. The TG-3 because of its smaller sensor will make getting shallower depth of field trickier and the Sony RX100 IV will produce extra detail having its extra 4MP. Greater resolution will also allow you to crop images a good deal more aggressively. The older TG-3 will be disadvantaged in sensor innovation.
