Fitting a FF and mattebox to my system
 

Hello,

I'm going to buy a support system from Zacuto for my sony EX1 and I would like to know if i'll have any problems fitting the Chrosziel Studio Rig FF with 2 handwheels and one of their matteboxes with swing-away action.
I'll also have an aditional 35mm adapter (Letus Ultimate) on the front of the Ex1 with still lenses attached. So the FF and the mattebox must fit these lenses.

I'm concerned that the follow focus won't fit below my still lenses when mounted on the adaptor. Being the 2 hanwheel model, will the shaft connecting the 2 hanwheels have enough space below the lens to properly function ? I don't have any experience with this and from the pictures i have seen of the unit it seems very unlikely.
Zacuto uses some .08 pitch zip gears to wrap around the still lenses so that they can be used with a FF unit. what kind of focus drive will I need from Chrosziel to work with ehse .08 zip gears ? They have many options to choose from and i'm totally baffled.

What about the mattebox. It looks higher than a normal one without a swing-away bracket and i'm afraid that it won't fit.

Any advice highly appreciated. Thanks!
