It had 9 elements and had a limited production run of 2000 lenses at a price in 1990/91 that made Leica lovers faint. In 1994 The second version has been inroduced, now as a normal production lens. Still 9 lenselements, but a different design (different surface and different technique, pressed). pressing is cheaper than polishing, but the change from two to one surface has been explained by Zeiss, who maintain that two aspherics generate more problems than they solve. Leica now seems to agree. So...either both Zeiss and Leica are lying, or the first version IS optically inferior to the second version....
