AFAIK The HC100mm is one of the original H line lenses, with no new version other than the faster 1/2000th Shutter. HCD[igital] lenses extend to cover the 24, 28 & 35-90mm (zoom), focal lengths. HC150(mm) had a 2nd version: "N". With the advent of of the H4D 200ms, Hasselblad updated two focal lengths; 50 & 120 with a version II.
I would need to check, but the H system was introduced at Photokina 2002 with the following lenses:
HC 35mm f/3.5
HC 80mm f/2.8
HC150mm f/3.2 (non-N)
HC 50-110mm f/3.5-f/4.5 zoom
converter 1.7X
The following year (2003), these lenses were introduced:
HC 50mm f/3.5 (version I)
HC 120mm f/4 (version I)
HC 210mm f/4
I am not sure when the HC 100mm f/2.2 and HC 300mm f/3.5 were introduced, probably 2003 or 2004.
Later, the following lenses were introduced:
HCD 28 (2006)
HC 150-N (2007)
HCD 35-90 and HTS (2008)
HC 50-II and HC 120-II (2010)
HCD 24 (2012)
Apparently, the optical differences between the HC150 and HC150N are minimal. From
this post at the time "
The Hasselblad HC 150mm f/3.2N designates a mid-production change to the optical design of the HC 150, pretaining to the zero-lead initiative in optical and electronic designs coming out of Europe. The optical design itself is practically identical, however the glass / optical formulation(s) are different. Physically the lens is identical to the earlier version, with the exception of the "N" designation."
