Does anybody have technical data on the Swiss made Schneider 355 mm f 8 gold dot dagor in compur 3? I just bought the lens but have not found any source for tec hnical specifications. I would be very interested in seeing MTF curves and lens diagram as well as hearing about the components of the optical glass used. If so mebody has the manufacturer4s manual of this lens, please help me out to get at least the information on it. General comment about the performance are wellcome too.
