No idea if its an apo design - although probably not! But don't dismiss a lens simply because its not of the "latest" design! The Fuji LF lenses have developed a "cult" like following!! They (apparently) have the best multicoating of any LF lens (Fuji EBC). I'm very happy with the Fuji - all my other lenses are Schneiders (all latest designs) and the Fuji is there with the best of them!
