trying to find out what size the front is of the RED 300mm to work out what is needed for a Arri MB-20 setup.

i found this quote from gibby who owns the 300mm red lens
The 300 prime has a gigantic diameter at the front end of the barrel - I haven't measured it, but I'd guess around 150mm. Fear not through! As I was figuring out possible filter options for the 300, I called Jarred Land and he tipped me off to a great feature of the lens: about 3" above the PL mount, on top of the lens, there is a small receptacle that pulls right out of the lens. It is designed for you to be able to screw filters into it and simply place the receptacle back in. The cool thing is that the thread diameter for that filter receptacle is only 43mm.

Although I used my 4x4 Chrosziel matebox (104mm) with no issues on it at the OCRT. Not the prettiest thing but it'll do.

While I can't find a picture of it, I promise you that an MB-20 will work with the 300mm. We used Blair's MB-20 II with a 114mm donut [his setup being built for the RED zoom] successfully on the 300mm.
