Ian,
Several problems. First, locking the mirror up will probably shorten battery
life to unacceptable levels. Second, this will most likely require some sort
of electro-mechanical system, which would increase manufacturing costs
beyond acceptable, as profits on digital cameras are razor thin now.
I would hope for a better evf as a solution in this area, and they are
probably either already available or nearly so, but I don't think there is a
groundswell of requests that will cause manufacturers to add this anytime
soon.
Fortunately, if evf's are like other things electronic, the subconrtactors
will likely move to higher resolutions, and force the issue, just not too
soon. We can only hope.
