There is a wish for 2x2 binning in this post

http://www.dpreview.com/forums/post/56670980

I answered that a number could tell the binning downscale, i.e. 2 means 2x2 and 3 means 3x3, etc.

Are there any problems with doing this to the DNG file?

It's not binning that's being asked for but rather output of
low-resolution Quattro images. This would be very easy to implement. It
just amounts to adding a switch that turns of expansion.

Isn't that part of the options to have during capture as well? Aren't they
basically saying they want to process all files as small until they get a
real keeper and then go big? I think that's a super useful feature as well.

What he asks for is an output of 5 MP when he has taken a 20 MP image, i.e. that we shall do binning (of the top layer in practice). Yeah, that sounds useful. Not maybe the most important feature, but an easy one to implement. And it is useful.
