Olympus E-M5 vs Sony A3000

Let's look a bit more closely at the Olympus E-M5 versus Sony A3000, one being a Advanced Mirrorless and the latter is a Entry-Level Mirrorless by manufacturers Olympus and Sony. The sensor resolution of the E-M5 (16MP) and the A3000 (20MP) is relatively well matched but the E-M5 (Four Thirds) and A3000 (APS-C) possess different sensor measurements.

The E-M5 was introduced 16 months before the A3000 which makes the cameras a generation apart from each other. Each of these cameras offer the identical body type (SLR-style mirrorless).

Before diving through a in depth comparison, below is a brief summary of how the E-M5 matches up versus the A3000 with regard to portability, imaging, features and an overall grade.

Here is a preview of the gallery photos for Olympus OM-D E-M5 and Sony Alpha A3000. The whole galleries are available at Olympus E-M5 Gallery and Sony A3000 Gallery.

For those who are planning to lug around your camera frequently, you need to think about its weight and size. The Olympus E-M5 provides outer measurements of 122mm x 89mm x 43mm (4.8" x 3.5" x 1.7") having a weight of 425 grams (0.94 lbs) while the Sony A3000 has specifications of 128mm x 91mm x 85mm (5.0" x 3.6" x 3.3") accompanied by a weight of 411 grams (0.91 lbs).

Remember that, the weight of an Interchangeable Lens Camera will change based on the lens you choose at that moment. Below is the front view over all size comparison of the E-M5 vs the A3000.

Using size and weight, the portability score of the E-M5 and A3000 is 81 and 69 respectively.

Often, it is very difficult to imagine the difference between sensor measurements simply by checking specifications. The visual below might give you a better sense of the sensor measurements in the E-M5 and A3000.

Plainly, both of the cameras offer different megapixel count and different sensor measurements. The E-M5 having a tinier sensor is going to make achieving shallower depth of field harder and the Sony A3000 will give more detail using its extra 4MP. Higher resolution will also enable you to crop photographs a little more aggressively. The older E-M5 is going to be disadvantaged with regard to sensor innovation.
