Thanks guys for all your help.
But I think I'm confused now. There's conflicting answers in here I believe.
Randy says the lens is as is with a constant film back size (22.2mm x
12.6mm), while Misho says I should use 0.96 conversion for the lens.
Basically it's a Red One shooting 3K with an 18mm lens.
Thanks again all.
