which filter system?

[stu]

I am trying to find the best filter system to attach to a Schneider 90mm super angulon XL that also allows a center filter to be used at the same time. Lee says they only make adapter rings up to 105mm and the front of the CF is 112mm with a 1.5mm thread. Can anyone help?

Lee also makes a custom 115mm press-on filter holder which fits the Schneider IVa center filter. It can be special ordered through Lee USA, also Robert White in the UK stocks it (www.robertwhite.co.uk, look under products and Lee filters).
