Arri IIC Matte Box Options

[John Jaquish]

Hello,

 

I have a IIC and am trying to come up with an option for using a matte box with the small Arriflex Standard Mount lenses. What I have now is this:

But I get vignetting at anything under 32mm or so in focal length. Being that I use the pistol-grip motor for handheld work, and not having an option for baseplate and rods, I'm looking for a way to use a matte box and ability for filtration with wider lenses.

 

I did find this version:

But I'm not sure if this would vignette as well with wider lenses.

 

Any suggestions would be greatly appreciated.
