Exactly the same problem with suites turning brown from tungsten and outdoors lighting, some suites end up with brown collars depending on the reflectiveness of the material
Still Sony isnt aware of the problem !!!!!
My local supplier is willing to supply an IR filter at there own cost
Being an owner of many Sony Cameras this is the first problem we have encountered its frightening the camera is unusable

wait just a minute guys. i just spoke to a Schneider rep last week at HD Expo. he stated that you'll need a IR filter only when using more than 4 stops(1.2) of NDs. i forgot the reasoning. is he wrong? I'm going to the DV Expo tomorrow. I'll talk to Sony and Schneider again about this issue. stay tuned...

i spoke with a Sony rep today at the DV Expo in L.A. and he was unaware of this issue and stated that such a problem could be fixed with a little tweaking in the PPs. it looks like we need to educate Sony on this issue. EX owners "mount up"!!!
the info below has been copied and pasted from Abel Cine Tech's website. for what its worth. here it is:
Formatt recently introduced a new technology in Infrared filtering. Their IR cut filters are "Hot Mirrors," which reflect only the light in the lower IR range of the spectrum. Unlike other IR filter designs, the Formatt IR cutting layer is sandwiched inside protective layers of glass and can be used facing any direction. Abel Cine Tech has tested the Formatt filters on the RED One camera and found them extremely effective at reducing IR pollution. Abel and Formatt have created a special bundle for a set of filters that is less than half the retail price.
When no or lower levels of Neutral Density filtering is applied (up to ND.9), many clients find that no IR cut is required. For high levels of ND (ND1.2 or greater), the need for an IR cut filter is definite.
