Pentax said in one of the interviews that the image circle of DA lenses were purposely made larger than that required for APS-C sensor in order to adequately cover the whole moving range of the SR system. I do not know if all DA's have the same image circle but people now know that at least DA40 does cover the 35mm (probably barely) without any visible vignetting. Maybe you might begin to see vignetting on 35mm as the focal length goes wider, but I am interested in seeing the actual results as you suggested, just out of curiosity.
