Only 2/3? Wow, I was led to believe from Sony's ads that only a very tiny amount gets reflected by the mirror. I don't consider 1/3 a tiny amount. I have wondered how much really does go through. I had guessed about 90% hits the sensor. I see some really unique tricks that Sony is up to with the pellicle mirror approach, and they should get some positive credit for their work; however, I've not been too attracted to this technology yet, mostly because it is taking some light away from the sensor.
