Yes, I'm very interested in this thread and plan to give HF a try soon.  The
lens design issue is a good one, too.  My counter-guess is that a focusing
rail could help as a workaround if the macro lens's focusing motions cause
ghosting.  That guess is based on not one iota of empirical evidence ;-)

The ghosting problem is a great question. Someone should check out the
effect of different lens designs. My guess is that IF lenses should have an
advantage as the front element isn't getting closer in focusing. But
certainly the more recent Nikon macros that change focal length while
focusing would be a very bad choice.
