The E-PM1 was manufactured 3 years prior to the a3500 and that is quite a serious difference as far as tech is concerned. Each of these cameras have different body design with the Olympus E-PM1 being a Rangefinder-style mirrorless camera and the Sony a3500 being a SLR-style mirrorless camera.

Before getting into a thorough comparison, here is a concise highlight of how the E-PM1 matches up versus the a3500 in regards to portability, imaging, features and an overall grade.

Usually, it can be difficult to envision the gap between sensor measurements merely by checking technical specs. The visual here should give you a greater sense of the sensor sizes in the E-PM1 and a3500.

As you have seen, each of the cameras have different resolutions and different sensor measurements. The E-PM1 featuring a tinier sensor will make getting shallow DOF trickier and the Sony a3500 will give you more detail due to its extra 8MP. Higher resolution will enable you to crop shots a bit more aggressively. The older E-PM1 is going to be disadvantaged when it comes to sensor tech.
