Well first most lenses are not good wide open. They perform best around 8-16.
However, most Rodenstock are certainly a lot better wide open than any Schneider I know of.
Currently I use two lenses I really like, the R. 40HR-W and the 90HR-W, both allow movements with the P65 and are extremely sharp.
Ups, just saw that you were looking for something in between. 35-90
Well perhaps the Schneider 47XL or 72XL, however I doubt that they will be on pair with the current top line Rodenstock, especially not wide open.
