Olympus E-M5 III vs Ricoh GR

Lets take a more detailed look at the Olympus E-M5 III and Ricoh GR, former being a Advanced Mirrorless while the latter is a Large Sensor Compact by manufacturers Olympus and Ricoh. There exists a considerable gap among the sensor resolutions of the E-M5 III (20MP) and GR (16MP) and the E-M5 III (Four Thirds) and GR (APS-C) provide different sensor sizing.

Take into consideration, the weight of an ILC will differ depending on the lens you are using at that moment. Underneath is a front view scale comparison of the E-M5 III versus the GR.

Taking into account dimensions and weight, the portability rating of the E-M5 III and GR is 80 and 90 respectively.

Sometimes, it is very difficult to picture the gap in sensor measurements only by viewing specs. The photograph here may give you a far better sense of the sensor measurements in the E-M5 III and GR.

As you can plainly see, each of the cameras provide different megapixel count and different sensor measurements. The E-M5 III having a smaller sensor is going to make getting shallower DOF tougher and the Olympus E-M5 III will result in extra detail using its extra 4 Megapixels. Higher resolution will also enable you to crop shots more aggressively. The newer E-M5 III provides a benefit with regard to sensor tech.
