More often than not, it is very tough to picture the gap between sensor sizes purely by checking specs. The picture here might offer you a greater sense of the sensor sizing in the Efina and RX1R II.

All in all, both cameras posses different megapixel count and different sensor sizes. The Efina with its tinier sensor is going to make achieving shallower DOF trickier and the Sony RX1R II will give more detail with its extra 28 Megapixels. Higher resolution will allow you to crop photographs somewhat more aggressively. The more aged Efina is going to be behind with regard to sensor innovation.
