Centre filter for rodenstock 90mm F4.5

[Former Member 8144]

Hi,

A couple of questions about filters on the rodenstock 90mm 4.5 lens.


I am looking for a centre filter for a rodenstock grandagon N 90mm F 4.5
I will be using fairly large camera movements (tilt and swing on the lens)

There is the rodenstock own E82/112 filter but I am wondering if there are other brands such as heliopan etc that people have used successfully also for this specific lens.

Now also looking at the rodenstock filter available the outside thread is 112mm...correct?

So lets say we want to use a polarising filter with this lens at the same time as having to use the centre filter...any suggestions?
Even the lee polarisers seem only to go up to 100 or 105mm.

What do people do?

Thanks,

Marc
