Optical viewfinders wipe the floor with any electronic one. Its maid that way for most semi and pro cameras because the photographer usually knows what he or she is going to get with out any electronic aid. Plus it feel's abit more traditional. Than theres photoshop to do the rest of the tweaking.

But your idea on those grids would be awesome. It would just be a overlay thing.

"A full frame camera under $ 1800 !!!

Noise? of course there's going to be noise, what do you expect at ISO 1600 ??? never used film? I wonder if people really know how to use their cameras."

I agree pisco $1800 is a bargain. But I wished high ISO noise was as nice as film though...
