With the 35mm Schneider, on a P65+, you can expect the following:
This is at apertures of F8 to F16. Any less and corner softness gets extreme any more and diffraction starts to show.
Left or right shift: This is with the Physical Center filter installed on the lens. For this lens the CF is a must.
10mm, no problems, with smearing or color sat, very slight magenta cast at edges which is totally removable with LCC
12mm, you will start to see a bit of detail smearing, and color sat will start to fall off. Magenta cast will show on far side of shift pretty much in a bar. It will be totally recoverable with the LCC
15mm, Really not useable IMO. extreme detail smearing from 12mm to 15mm, quite a bit of color/sat fall off (some of it is recoverable), extreme Magenta shift showing as a dark bar along the outer shifted edge.
Past 15mm, really not useable.
If your subject has a solid color in it, like a blue sky or white building then the magenta cast on a 12mm shift may or may not be workable. I have found it very subject dependent.
With rise or fall, you can expect just a little bit more from this lens on the P65+/160. For some reason, you get just a bit more it seems with rise and fall.
For my work, the 35mm on the P65+/160 will not allow enough shift for a true pano. @ a useable amount of only 10mm to each side. You may be able to get quite a bit more with the P45+. When I tested the 43mm Schneider on my P45+, I was able to use it easily to 20mm of shift right and left on the P45+, however on my IQ160, it's max is about 17mm and that is push.
