I am about to buy either a 45 or a 55 for my P67. My question is if one can use the Cokin Filter Holder size P without any vignetting with either the 45 or 55? The 45 I know requires a 82 mm filter but since Cokin makes a adapter for 82 mm threads this will fit in theory. The 55 has a smaller thread (77 mm) so how about that combination?

Hi Michael, I had used the P-System with the 45mm, with different results. The polarazing filter from Cokin will show heavy vignetting. The half-color filter (I don4t know the english word for this kind of filter) can be used, but I have modified the P holder. I get an old version of the holder (not so round-shaped like the new one) and cut the first 2 holding stripes off. So I can only use one filter in this holder, but this special version works also with my 20mm lens (35mm format).

Hope I can help you Re
