See:-http://egami.blog.so-net.ne.jp/2011-02-12#englishCanon made a half mirror called "pellicle". Sony made a half mirror and called it "translucent". Whilst both are fixed, Nikon have thought about to make it movable!So, what is the point? I just wonder.. When the mirror can be moved, it does not need to be semi-transparent. When it is semi-transparent, it does not necessary to be moving. Why
