Those photos that you posted are some of the largest I have seen on this website. Are they 100% blowups? When the shutter speed is appropriately maintained, do you see a significant sharpness difference with the 45mm and 90mm lenses with the adapter on a m4/3 camera vs what it is with the Contax G1 or Contax G2? I was hoping to use my 45 CZ lens for portraits and the 90mm CZ lens as a telephone. On my Contax G2 these lenses are extraordinarily sharp.
