Purple fringing is a problem associated with DSLR sensors, that can be
kept in check with proper lens design. I should have said that the
100mm f/2.8 FA macro and the 135mm f/2.8 FA lenses can contribute to
purple fringing on DSLRs, though at least in the case of the 135mm FA
lens, I've had very good results on my *ist-DS, and only once noticed
purple fringing. YMMV.

D-FA 100mm f/2.8 Macro: Optimized for digital. Presumably less
suceptible to purple fringing and the like than the FA version, though
I've heard very few complaints about the FA.
