OConnor C1243-1123 overview

  • 1Description

Designed for use with the O-Box WM matte box, the OConnor Clamp Ring (150-114mm) fills the space between a lens with a 114mm front barrel and the 150mm diameter of the matte box back. This ring's split design allows for gentle compression for securely fastening the matte box around the ring and lens. Use this ring to help prevent flares and reflections from any filters from entering the lens.

    OConnor C1243-1123 reviews

    Step-Down Clamp Ring (150-114mm) is rated 4.4 out of 5 by 5.
    Rated 3 out of 5 by from Solid fit, works great, costs a lot This is something I can only give 3 stars b/c it's just stupidly expensive. I know film stuff costs a lot. (I have over $5k of camera/steadicam/AKS cables...)But these clamp rings take the cake. With the 150mm to 114, I've got zeiss superspeeds and my RED PRO Zoom 17mm-50mm covered, but I need 110mm for Pancros, and 95mm for (most) ultra primes... It's ridiculous. Can't they sell them all in a single set? B/c most people need all of them. Honestly, they should just sell it with the whole matte box. It always feels like they're nickel and diming us to have all these little things you need. The fact that the Obox does not have the side flag brackets (let alone the actual flags), is part of it. Rant aside, they fit well and work well. The Obox is a fairly heavy matte box for a non-swing away box...and I was a little skeptical that it would be solid enough, but its great.

    Rated 5 out of 5 by from Solid Like The O'Box Used this ring with a Zeiss CP.2 primes. The fit is PERFECT. Solid connection and absolutely no light transmission. Used the ring to connect the mattbox to the lens with no rails. I don't know if this is recommended but it work great. I got the entire set so I could use with many different lenses. This set really completed my O'Box setup.
