Looking at the quantum efficiency data at sensorgen.info (derived from DXomark), Nex7 is 47% and a77 is 35%

That corresponds to a 0.43 stop loss, and i believe it is safe to assume that this difference i solely due to the mirror?

That is correct and is why he loss is often claimed to be 1/3 to 1/2 stop.
