Since we know it has the same sensor as the A6000, SLT = 1/3 stop of light loss, so obviously whilst it's going to be 'worse', we know how much worse..

So you think you 'know' this? Sounds like you 'know' what Sony tell you. I 'know' from the results that the A77 noise was one stop away from its rivals. I didn't rely on a manufacturer making a figure up to impress me to judge the images. People can step back and reason that if 1/3 stop loss were true, it would give only 1/3 stop of light to the autofocus system, which would put it far behind its competitors.

Perhaps Sony are simply lying and that the loss in the mirror is at least 1/2 stop. Their claims would be easy to prove if anyone cares to remove their mirror and shine a torch through it.
