I have a Chrosziel 16x9 dual stage matte box that I use for Super 16 and Super 35mm 3 Perf formats. I asked Chrosziel for hard mattes but they don?t make them for film. This seems a bit silly as they make the matte boxes, go figure.
I use Zeiss Super Speed 35 primes on both formats. I?m thinking of making a set of hard mattes ? it would seem strait forward ? just cut out a hole ;-) - Arri is looking up the opening dimensions for Zeiss Super Speed mattes 18,25,35,50,85 (Mk III).
But before I do my arts and crafts bit I was wondering if anyone has done this before. Any suggestions on materials? Maybe I can rig a set of Arri Mattes for the Chrosziel?
Thanks in advance.

Just make sure that the mattes do not cover the glass of the lens,
Thanks for your note. If I make some I'd try to get them to attach to the outer front of the box - like the Arri mattes - with a bit of a lip so they fit over the opening. I'm fairly confident I could knock some up out of thin aluminium sheet metal and shoot them with flat black. The trick is the opening for the different focal lengths for the Super 35 format - trying to modify Arri plastic mattes may be my easiest path ? I?ll try them on my box the next time I visit Uxbridge / Arri Media. I was hoping some after market company made some without the Arri price tag?..

Just make sure that the mattes do not cover the glass of the lens, othwerwise they could cut down the light that reaches the filmplane, resulting in underexposed shots. This additional 'stop' effect is most obvious when wide open.
Precisely. Also look out for out of focus highlights taking on the shape of the matte. I hate mattes. Completely unnecessary 98% of the time with good lenses.
