Usually, it can be hard to envision the gap in sensor measurements only by going through specifications. The visual here should offer you a much better sense of the sensor sizing in the 1 J5 and a5100.

To sum up, both cameras feature different resolutions and different sensor measurements. The 1 J5 using its smaller sensor will make shooting shallower depth of field more difficult and the Sony a5100 will provide greater detail because of its extra 3 Megapixels. Higher resolution will help you crop shots way more aggressively. The more modern 1 J5 is going to have an advantage with regard to sensor tech.
