Olympus E-M5 vs Pentax K-S2

Below is a in depth overview of the Olympus E-M5 and Pentax K-S2, one being a Advanced Mirrorless and the other is a Entry-Level DSLR by brands Olympus and Pentax. The resolution of the E-M5 (16MP) and the K-S2 (20MP) is very comparable but the E-M5 (Four Thirds) and K-S2 (APS-C) provide totally different sensor sizes.

The E-M5 was manufactured 3 years earlier than the K-S2 and that is a fairly serious gap as far as camera technology is concerned. Both of the cameras feature different body design with the Olympus E-M5 being a SLR-style mirrorless camera and the Pentax K-S2 being a Compact SLR camera.

Before getting right into a comprehensive comparison, here is a short summary of how the E-M5 grades against the K-S2 with regard to portability, imaging, features and an overall grade.

Sometimes, it is very difficult to visualise the contrast in sensor measurements simply by going through specifications. The graphic below should give you a more clear sense of the sensor sizes in the E-M5 and K-S2.

To sum up, both cameras come with different megapixel count and different sensor measurements. The E-M5 because of its smaller sensor will make getting shallower depth of field tougher and the Pentax K-S2 will provide extra detail due to its extra 4MP. Greater resolution will also help you crop images a good deal more aggressively. The older E-M5 will be behind with regard to sensor technology.
