Yes, I did use the Schneider 35mm in a way that corroborates what I am writing: both lenses have similar shift ways in both directions. And of course, the Rodenstock can as well be used on the Bicam (though I did not use it on it). Adam, in his post above and responding to mine, seems to say that he can use a shift of up to 18 mm with the Schneider 35 mm. I believe him, I don't have the experience he has with this lens. But he says also, that the sharpness drops towards the edge: then it depends effectively if this drop is in a "sky" part of the image, in which case it doesn't really matter, or in a part where you need maximum details and resolution.
Yes, I have the Rodenstock HR 4.0/35 mm (Sinaron Digital 4/35 mm HR) and have use it. It has some visible distortion when shift to the maximum mentioned, but it can be corrected. And yes, that's what I meant, the Schneider figures are in one direction (up or down, resp. left or right), and that's why I have added both directions. And Rodenstock ALSO give the figures in one direction, BUT my findings, and this of many other users of this lens, is that you can easily go 4 mm more in both directions.
But one advantage, IMO, is that you can use the Rodenstock digital HR lenses full open without loss, or very minimal. The Schneider Digitar need, again IMO, to be stopped down by 2 f-stops.
That's all what I wanted to say, and it does by no way mean that I find the Digitar 35mm to be a bad lens or even inferior. It is of course an outstanding lens.

Thanks, Thierry. Good job I'm generally not using it at f4, but at f11-f16. With the 38SA, I can go simultaneously 16mm vertical and horizontal in either direction without loss of quality (there is some falloff, corrected with a CF). So, both lenses would be usable on the bicam.
Any chance you can answer my question though? I am assuming you have this lens and use it. Forgive me if it is a wrong assumption.
How much simultaneous shift can you do with the Rodie lens? The Schneider figures on their website and publications are for shift in ONLY ONE direction, and I might assume Rodenstocks are quoted in the same way.
TIA
