An optical graycode wheel and miniature sensor array on the aperture feedback system would be both inexpensive and very reliable. I think the costs and other issues relating to the aperture feedback control have been blown out of all proportion. They could have done it at minimal cost if they wanted to, they simply chose not to, and only user backlash forced them to implement the green button kludge. It seems like they aren't about to make the same error on the D645 and cost has nothing to do with it IMHO.
