Freont Diameter RPP´s

[Manuel Wenger]

Waitng to get my lenses in the next few weeks.
Scratching my head over different front diameters for the lenses.

I remember a post saying 114mm is the way to go, on red.com it says 110mm and 138mm for the 300mm Lens, want to buy the right donuts for my Matteboxes but i´m a bit unsure which way to go. I´m quite sure the 300 is not 138mm diameter, they might have mixed it up with the 18-85 ??

thanks
Manuel

They are 110mm fronts. Arri doesn't make 110mm bellows I believe thus you have to order a 114mm bellows with 114 to 110mm step down Ring.

That depends on your matte box. My MB14 has a 110mm bellows and my LMB15 has a stepdown from 130mm. Also the internal threads are 105mm if that helps. You are going to be stoked on the RPP's.

What are people using for clear filters on these for protection that wont affect lens performance?

Thanks
