Olympus E-M10 IV vs Sony G3

Lets take a deeper look at the Olympus E-M10 IV versus Sony G3, one is a Entry-Level Mirrorless and the latter is a Small Sensor Compact by competitors Olympus and Sony. There exists a sizeable gap between the sensor resolutions of the E-M10 IV (20MP) and G3 (10MP) and the E-M10 IV (Four Thirds) and G3 (1/2.3") provide different sensor dimensions.

Photography Glossary

The E-M10 IV was introduced 11 years after the G3 which is quite a large gap as far as technology is concerned. Both of these cameras have different body design with the Olympus E-M10 IV being a SLR-style mirrorless camera and the Sony G3 being a Compact camera.

Before we go right into a in-depth comparison, here is a brief summary of how the E-M10 IV scores against the G3 in regards to portability, imaging, features and an overall mark.

Keep in mind, the weight of an Interchangeable Lens Camera will vary based on the lens you have chosen during that time. Following is a front view sizing comparison of the E-M10 IV against the G3.

Taking into account dimensions and weight, the portability score of the E-M10 IV and G3 is 81 and 94 respectively.

More often than not, it's hard to imagine the contrast between sensor dimensions purely by looking at specs. The pic below will help give you a far better sense of the sensor dimensions in the E-M10 IV and G3.

As you can plainly see, the 2 cameras have different resolutions and different sensor dimensions. The E-M10 IV with its bigger sensor is going to make achieving shallow depth of field easier and the Olympus E-M10 IV will resolve more detail using its extra 10 Megapixels. Higher resolution will also make it easier to crop shots a bit more aggressively. The fresher E-M10 IV should have a benefit in sensor tech.
