Thanks everyone for your posts. @bvukich: sounds great, what phase one provides. but full implementation in future dslr's would be quite expensive as I can see. Thanks again and regards. Pedro
Its always possible that the next new generation of Digic Processors will support pixel binning. Its one of those things that Canon and Nikon have so far not implemented. Its just something that has not yet been deemed necessary for the relatively low pixel count cameras. When we hit 40 or more MP, it might be needed.
