I'd like to have an SLT-mirror that flips up during the shot

BTW not only show the DPREVIEW lab results a difference in noise, but also DxO Labs state a substantial difference, A57: 785 low light ISO, compared to 1079 for the NEX5N.

To be exact, their measurements show the effects of the extra gain (between 0.33 to 0.5 EV) to compensate for the light "loss". They do not show what you attempted to describe here as a second noise factor:

" .. adds noise, and I mean not because it "eats" some light, but mainly because it is an optical obstacle in front of the sensor that is not entirely clear like only lenses "

And what you call substantial is exactly 0.46 EV (0.34 EV when comparing the NEX 7 and A77). This is no secret to anyone in here from what I can tell and has been discussed since the first SLT release more than 2 years ago.
