Olympus E-M1 vs Ricoh GR II

Let's take a more detailed look at the Olympus E-M1 and Ricoh GR II, one being a Pro Mirrorless and the other is a Large Sensor Compact by competitors Olympus and Ricoh. The sensor resolution of the E-M1 (16MP) and the GR II (16MP) is fairly close but the E-M1 (Four Thirds) and GR II (APS-C) boast totally different sensor sizing.

The E-M1 was unveiled 19 months earlier than the GR II making them a generation apart from each other. Each of the cameras have different body design with the Olympus E-M1 being a SLR-style mirrorless camera and the Ricoh GR II being a Large Sensor Compact camera.

Before diving into a full comparison, here is a brief highlight of how the E-M1 grades vs the GR II in regards to portability, imaging, features and an overall grade.

Below is a sample of the gallery pictures for Olympus OM-D E-M1 and Ricoh GR II. The full galleries are viewable at Olympus E-M1 Gallery and Ricoh GR II Gallery.

If you are looking to lug around your camera regularly, you're going to have to think about its weight and size. The Olympus E-M1 has outside dimensions of 130mm x 94mm x 63mm (5.1" x 3.7" x 2.5") accompanied by a weight of 497 grams (1.10 lbs) and the Ricoh GR II has specifications of 117mm x 63mm x 35mm (4.6" x 2.5" x 1.4") and a weight of 251 grams (0.55 lbs).

Factoring in size and weight, the portability score of the E-M1 and GR II is 71 and 89 respectively.

In many cases, it can be tough to visualise the difference in sensor measurements purely by researching specs. The photograph underneath will help offer you a more clear sense of the sensor sizes in the E-M1 and GR II.

All in all, each of the cameras provide the same MP but not the same sensor measurements. The E-M1 features the smaller sensor which will make achieving shallower depth of field harder. The older E-M1 will be behind when it comes to sensor tech.
