Pentax K-50 vs Sony A7c Sensor Comparison

Clearly, the two cameras enjoy different megapixels and different sensor sizes. The K-50 featuring a tinier sensor will make achieving shallow DOF more challenging and the Sony A7c will resolve extra detail as a result of its extra 8 Megapixels. Higher resolution can also make it easier to crop photographs far more aggressively. The more aged K-50 is going to be disadvantaged with regard to sensor technology.
