Olympus E-PM1 vs Sony NEX-6

Here is a detailed overview of the Olympus E-PM1 and Sony NEX-6, former being a Entry-Level Mirrorless while the other is a Advanced Mirrorless by competitors Olympus and Sony. There is a considerable difference among the resolutions of the E-PM1 (12MP) and NEX-6 (16MP) and the E-PM1 (Four Thirds) and NEX-6 (APS-C) have different sensor measurements.

The E-PM1 was revealed 16 months before the NEX-6 making them a generation apart from each other. The two cameras have the same body design (Rangefinder-style mirrorless).

Before diving right into a in-depth comparison, here is a concise summation of how the E-PM1 matches up against the NEX-6 in relation to portability, imaging, features and an overall rating.

Here is a sample of the gallery pictures for Olympus PEN E-PM1 & Sony Alpha NEX-6. The full galleries are available at Olympus E-PM1 Gallery & Sony NEX-6 Gallery.

In case you're intending to carry your camera, you'll need to factor in its weight and proportions.

Usually, it is difficult to picture the gap in sensor sizing purely by looking through technical specs. The graphic underneath might offer you a greater sense of the sensor sizes in the E-PM1 and NEX-6.

As you have seen, both of these cameras provide different megapixel count and different sensor sizing. The E-PM1 using its smaller sensor is going to make shooting shallow depth of field harder and the Sony NEX-6 will provide you with more detail because of its extra 4MP. Greater resolution will make it easier to crop photos more aggressively. The older E-PM1 will be disadvantaged with regard to sensor innovation.
