Been holding my breath (and fingers)trying not to respond but too much bait has been laid...I strongly suspect the 95% is due to 'room' and the pop up flash takes up too much. Drop the flash--heck no...this camera is clearly for a serious amateur (who doesn't always carry flash equipment). The Canon D5 has captured quite a market for the full frame (I want my wides back set). This is Nikon's response.
Are there pro photographers who have serious dollars on the line--Yes... Do they need the 100% viewfinder for instant critical framing decisions Yes...BUT if you are in that line of work and framing is that critical...if the 100% viewfinder is that absolute critical...you already have your camera--it is called the Nikon D3. Buy that camera--it is the one you need.
