I will be looking for a manual focus Nikkor 85. I do not need the extra speed (or cost) of a 1.4, and so a 1.8 or f/2 would be fine. I plan on using this "portrait" focal length in a somewhat atypical manner--i.e. outdoors. Thus, sharpness will be essential. In certain situations, I will use the lens in a more conventional manner, too. Which 85 would be best--the AI 1.8, 1.8 H, 1.8 HC, AI f/2...? Please be as specific as possible.
