I'm searching for a HC 50mm lens for my pal Ed Richter. I found a H3D-II 39 and Hc 100mm for him here on GetDpi, and now he needs a 50mm.
It can be the older version as it is fine for the 39 back, but should be in EX condition. If you have one, PM me and let me know how many shots on it please. Then I'll hook you up with Ed (whom I can personally vouch for).
