David is correct. However, another suggestion is using
a camera such as the Panasonic DMC-FZ20
http://www.dpreview.com/reviews/panasonicfz20/
It allows you to use the LCD or the viewfinder, but as
David implied there is no mirror. The FZ20 and other
cameras like it basically duplicate what the CCD sees
on both the back LCD and the viewfinder LCD.

Just my 2 cents worth of suggestions...
