I agree with the preview idea. That's one thing that needs
to be added to dSLRs .... and is in fact being added by makers.

I like the real optical view. But I'd also like a live histogram
superimposed on a preview on the screen. Since this requires,
other than software, just a mechanism to hold the shutter open
without eating battery power, WHY NOT?
