Filters for Rodenstock 90mm f4.5 Grandagon

[Terrance Wong]

Can one use B+W 82mm filters with this lens? I'm concerned that the filter glas s will touch the front lens element due to the large curvature.

1/I have a similar question for my Sinaron W90mm f4.5 lens.Would screw on type f ilters workwith these lenses considering the huge size,assuming one can afford t o buy them in the first place? 2/Would it be possible to use a rear mounted polariser with precision? 2/Does Sinar have a website ?
