Typically, it can be difficult to visualise the contrast between sensor sizes simply by looking at a spec sheet. The image underneath should provide you a more clear sense of the sensor sizing in the K-50 and A7c.
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.
