SLTA7? A657? :-)

What I'm curious to see is if this has better IQ than the A77, since the
SLR will lose some light due to the pellicle mirror. The NEX 7 might be
a half-stop better in ISO performance. And I wonder if there's any
optical degradation due to the mirror?

There must be. Every extra optical surface will cause some
degradation. But how much does that matter at the back of a
several-element lens? How many people do you know who preferred a 6
element lens over a 7 element lens because of the extra optical
degradation of the extra glass?
