I too have the 35mm S (had it for a few months now). The lack of distortion in a MF lens this wide is spectacular. I used to use the Zeiss/Hassy 40 CFE/IF lens and thought that was the most spectacular of all these types of lenses but the S35 simply takes the prize. I can't compare it to offerings from Rodenstock and Schneider as I have never used those but most others I have and I would take this one over all. I really look forward to your work with them.
