Again Dan, I based on the samples I saw (including your portraits), I did like the rendering. The 75 Cron and the 0.95 nocti are the only two Leica lenses whose rendering really appealed to me. (based on samples here and on flickr and other places)
In practice now after buying it, I do have some reservations - there are situations where I\'m not crazy about the rendering. There are other situations where I really like it. So my series of images and comments are part of a process of learning the lens and how I should best use it.
