Wide Lenses With 4x4 Matte Box

When shooting 35mm, what's the widest lens you can use with a 4x4 mattebox? In other words, at which focal length do you have to switch over to a 6x6?

Got a producer breathing down my neck about renting both matte boxes and filters. We're carrying a 14mm for the entire week, but only day playing the 8mm. Honestly, I've never worried about this nit-picky stuff, but now I've got to give this guy an answer.
Thanks for any info.

Are you talking 4x4 clip-on or studio MB ? The latter can stick out further and vignette easier specifically when you're also using a round filter in the back (such as a Pola or Diopter). Off hand I think your 8mm will definitely vignette on a 4x4. I don't even know if the 14mm is safe, and if its Super-35mm its even more a step-up to 6.6x6.6 inch (plus there you have 4 stages). I think that even the 14mm is close to vignetting on a 6x6 when you're using a 138mm filter (older 6x6's vignette more than the newer Arri's). Certainly not a lot of room to slide the grads around.

Also, you may look into getting 4x5.65 inch filters & MB instead. You can still use 4x4's provided you get the trays. But if you use 4x5's horizontally you vignette less on the sides.

Generally speaking, you can go as wide as a 16mm lens with a 4x4 matte box.

The 14mm is just too large and would probably vignette anyway. As the 8mm, there is no matte box which I am aware of which will clear an 8mm lens.

The 8mm has a field of view of 170-180 degrees. The physics just don't allow any matte box or front filtration!

What's the widest angle lens you can use in 35 and still use a 4x4 mattebox without vignetting? Is it an all purpose situation or does it depend on the mattebox in question? I've got a job next week with a producer who doesn't want to rent a 4x4 and 6x6 mattebox with all the filters. We're day playing an 8mm and I know we'll need the 6x6 for that one, but what about a 14mm?

Thanks folks.

Jake,

Don't sell yourself short & get the 6.6 matte box. At least you are pretty much covered for most lenses. You will cover a 14mm Cooke S4, Ultra Prime & Zeiss std lenses with a 6.6 matte box, even in super 35 wide screen TV.

In Australia a 4x4 matte box comes standard with the camera kit as part of the package & the 6.6 is an extra expense. In the grand scheme of things, a 6.6 matte box is 'petty cash' when you look at the price of a whole kit!

I use a 4x4 Arriflex matte box on my BL, but I have to take it off when using the 18mm. If I am using a filter or getting flares and want to keep it on, I pull the donut off and slide the matte box back a bit and it works.
