SP AF90mm /2.8 Di MACRO 1:1 (Model 272E)
Unlike conventional lenses designed to cope with internal diffused reflections of the mirror box and film surface, Di lenses offer new anti-reflection countermeasures that are essential in lenses designed for use with digital cameras. The new SP AF90mm Di (Model 272E) features an improved coating technology that reduces the reflections that are likely to become a problem, to the absolute minimum.
