A thought on the coding of lenses vs. Sean's idea of the manual selection: With the crop factor of 1.33 my CV 21mm/F4 becomes a much more important lens for me now. It's now a 28mm - a lens I use much more than the 21. If I can't select the 21mm manually then I really can't use it as far as I'm concerned. I need to be able to rely on accurate color across the lens and do not want to make fixes in photoshop to the corners.
