I notice so far only the 1Ds offers zero Conversion factor on Lens ie: a 28-70mm IS 28-70mm. .. I was hoping 1D Mark II to hv this feature but I dun think so.. becoz' I hv some lens with my old EOS 5, but not feeling good with the Digital camera's conversion factor... anyone hv idea if Canon coming out with any zero conversion factor lens system soon ? thanx
