Wow. I just found your email from August. Looks like we were working on a shipping quote and the thread got marked closed by accident in our ticket tracking system so no one followed up. Very sorry! We try to get back to everyone one that reaches out.
I'm interested to know what ND filters you used? I ran a Tiffen variable ND canon 24-105 f4 on my test footage and didn't notice IR pollution. By no means am I doubting you because it's clear that its there in your test for sure. But now you have me thinking I should do a real test since yall didn't notice at first as well lol.
For all I know Tiffen's VND has some IR cut in it haha. Our 4x5 NDs were: 1.8 Schneider 1.2 Tiffen ND 1.2 Tiffen IRND 0.9 Marumi WSND 0.9 Tiffen Waterwhite ND 0.9 Tiffen IRND At least that's what I've written down in my notes
thats too bad you guys dont reply to customer emails i asking how much an m18 shipped to me would be

Thank you for sharing! That’s important and seriously concerning. Glad you brought this to our attention.
Thank you, just yesterday talked about renting this camera for a test. Very useful info
Good info. Thanks for sharing.
Rawlite IR/Anti-aliasing filter for the sensor is what you want to look at and possibly a lucAadaptor to make the camera full frame.
Oh interesting it's literally made to bolt into the camera body aye?
Is Blackmagic aware of this issue?

@@Owlbot Thanks for the quick response, ill have to take a look at it and see whats going on with it.
My tiffen Variable ND has a green shift to it so potentially that's countering the infra red push? Not sure it's ideal though haha but if it works.
Does this only occur when an ND is used without an IR cut filter? Or will this happen irregardless if having an ND on or not?
Only when nd is used in very strong sunlight.
T H A N K Y O U !
ND filters block visible light, not infrared or UV.
That’s the simple answer, and there is more to it than that.
