Nikon Filed a Movable Half-mirror SLR Patent, is there Any Point?

See:-

http://egami.blog.so-net.ne.jp/2011-02-12#english

Canon 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 tries to make both at the same time? To get the best of both worlds or maybe actually, just to get the worse things of both?? (Just read the last comparison table in the above link to find out more..)

a) It's a feature called ISO boost where they can get in more light by getting the translucent mirror out of the way

b) They don't want to infringe on any translucent mirror copyright, so they go around it by making it movable

c) They can't think of any name for it

d) any other illogical ideas here

In order to make a real technology breakthrough, I suggest Pentax to make a DSLR that has a full (non-transparent) mirror that is fixed (not movable)!! ;-D Lol..

10 years from now, the mirror will serve as a dual purpose electronic thingy where it will act as a mirror first, then transform into a sensor when you press the shutter.

It is not known however if the FF tungsten issue will be fixed by then.

The tungsten FF issue of the Pentax DSLR *was* NOT there 10 years ago and before. At least all of my MZ film cameras did not suffer much from the problem! :-(
