Olympus E-M1X vs Pentax K-x Sensor Comparison
Oftentimes, it's difficult to visualise the gap in sensor dimensions purely by seeing specifications. The picture here will give you a far better sense of the sensor dimensions in the E-M1X and K-x.
Plainly, both cameras have got different megapixels and different sensor dimensions. The E-M1X with its smaller sensor will make shooting shallow depth of field more challenging and the Olympus E-M1X will show more detail using its extra 8 Megapixels. Greater resolution will allow you to crop pics much more aggressively. The more modern E-M1X will have an edge with regard to sensor tech.
