Optical constructionThirteen elements in nine groups. Defocus Smoothing coating on two lens surfaces gradually lowers transmission towards their edges, softening out-of-focus highlight outlines without softening the focused subject; Digital Camera World reports about 1⅓ stops less light transmission at f/1.2 and a T2.2 transmission rating10 elements in nine groups
Coatings–Super Spectra coating
Aperture detail–Maker minimum aperture f/22 at14mm and f/38 at30mm using half-stop display; Ken Rockwell reports f/36 at30mm, while Digital Camera World lists f/32. Main values retain the maker’s explicitly stated display convention
