Olympus E-M1X vs Pentax K-3

Lets take a deeper look at the Olympus E-M1X versus Pentax K-3, one being a Pro Mirrorless and the latter is a Advanced DSLR by competitors Olympus and Pentax. The sensor resolution of the E-M1X (20MP) and the K-3 (24MP) is relatively comparable but the E-M1X (Four Thirds) and K-3 (APS-C) use different sensor dimensions.

The E-M1X was brought out 4 years later than the K-3 and that is a fairly large gap as far as camera tech is concerned. Both of the cameras come with different body type with the Olympus E-M1X being a SLR-style mirrorless camera and the Pentax K-3 being a Mid-size SLR camera.

Before delving straight into a in-depth comparison, below is a concise summation of how the E-M1X matches up versus the K-3 in terms of portability, imaging, features and an overall rating.

Oftentimes, it is very hard to imagine the contrast in sensor sizing only by going through a spec sheet. The graphic underneath will help provide you a far better sense of the sensor sizing in the E-M1X and K-3.

Clearly, both the cameras posses different megapixel count and different sensor sizing. The E-M1X due to its smaller sensor is going to make shooting shallow DOF tougher and the Pentax K-3 will show greater detail having its extra 4MP. Higher resolution will help you crop shots somewhat more aggressively. The younger E-M1X provides a benefit with regard to sensor technology.
