The E-M10 was unveiled 3 years after the NEX-5 which is quite a sizable gap as far as technology is concerned. Both of these cameras have different body design with the Olympus E-M10 being a SLR-style mirrorless camera and the Sony NEX-5 being a Rangefinder-style mirrorless camera.

Before going right into a comprehensive comparison, here is a quick summation of how the E-M10 grades versus the NEX-5 with regards to portability, imaging, features and an overall score.

Typically, its difficult to imagine the gap between sensor sizes just by reading through a spec sheet. The image underneath should offer you a much better sense of the sensor measurements in the E-M10 and NEX-5.

As you can see, the 2 cameras have different megapixel count and different sensor sizes. The E-M10 with its tinier sensor is going to make shooting shallower depth of field more difficult and the Olympus E-M10 will give you extra detail having an extra 2MP. Higher resolution will help you crop shots a bit more aggressively. The younger E-M10 should have an advantage in sensor innovation.
