Filter size for RED 18-85mm?

[Victoria C]

I have a RedRock mattebox on order, and I understand it will work with the 18-85mm. Will 4x5.65 filters work with the lens, or do I need to get larger filter trays and filters? What is the minimum filter size that will work?

Please educate me! :nerd:

You will want 5.65x5.65 for any filters you wish to rotate, such as grads or polas. Also none of us know the specifics of the 18-85 just yet and how its FOV or coverage translates to the RED S35 sensor area. There is a chance that 5.65 filters could still vignette or even cause outright obstruction, especially when rotated towards a 45 degree position.

Thanks Jeff. I think I'll hold off on ordering filters until we know more. I appreciate the advice.
