Soon there will probably really be Zeiss lenses for Nikon - the images certainly don't look like fakes. Okay, on January 18th we will know for sure, but it already looks very likely that Nikon will become the new Contax. Maybe there will also be optics with Canon adapters in the long run. On the other hand, I am very satisfied with my Canon macros and at least in that area I have nothing to complain about. Nevertheless, some of the Zeiss lenses on a digital camera would of course be quite nice - especially if they are well integrated (the adapter solutions for Canon are unfortunately only suboptimal).
