What needs for O-box to work with 114, 65, 87 mm and any different lenses?

[Alexey Datsenko]

Tell me please how work O-box, it is hard to understand what need additionally buy to work with it.
I see filters holds at the back of O-Focus Clamp Ring 150-114mm but many people use 138 bellow ring but at the Oconnor accessory there is now any 138 bellow rings

What is it 138mm bellow to 114mm ring?

So I need Bellows Ring 150-114mm or find some 138 Bellows Ring?
And I see a lot of Clamp Ring but what in this case i need Reduction Ring
Foe example if i Can use Clamp Ring 150-80mm for 80 mm lenses why need I to install Bellows Ring 150-114mm firstly and then Reduction Ring 114-80mm if I can instal for 80 mm lense initially 150-80mm?

How work with O-Box tell please hot is it work?

I insert filter in filter frame? Then I instal Bellows Ring 150-114mm or this some unknown 138mm bellow to 114mm?
and then i install some Reduction Ring?
And how O-box can work with for example Zeisse ZE 50 mm it is 67 mm diameter if the minimum Reduction Ring is 114-80mm?

I'm not sure what you're trying to ask in your post, but here's how I do it.

Get the 150-114mm Bellows. This will allow you to use 138mm circular filters.
From there, get the following reduction rings: 114-110, 114-95, 114-80. This will allow you to throw on many cinema and still glass with the corresponding front diameter. Should you have glass with front filter diameters of 67, 72, etc.. you will need to get step up rings for those lenses and screw them on. For it to work with the O-Box you want to get step up rings to 77mm. Once it's on the lens, it'll slide right into the 114-80 reduction ring.

If you're planning on using the O-Box as a clamp on solution, then getting the rubber bellows is pointless. You'd have to get all of the clamp on rings from 150mm to X (Whatever mm front thread).

Thanks Shervin
And why do I need 138mm circular filters? I thought O box is for 4x4 and 4x4.56 or is it just additional possibility to work with 138mm circular filters? But if I am not planning now (maybe in future) to use 138mm circular filters I really don't need Get the 150-114mm Bellows? I just can buy Clamp Ring 150-114mm or Clamp Ring 150-80mm? And it is enough?

For example I want to work with CP.2 or Zeisse ZE I just buy Clamp Ring 150-114mm or Clamp Ring 150-80mm and can work with it?
What is the difference between Clamp Ring and Reduction Ring? for example Clamp Ring 150-80mm and Reduction Ring 114-80mm?

 

[Shervin Mandgaryan]

If you want to use 138mm filters in the future, you have to forgo the clamp on ability of the O-Box and use the 150-114 bellows. If you don't, then stick with clamp on rings.

CP.2's have a 114mm diameter, so you have to either get the bellows or the clamp ring for that diameter.

Reduction ring works with the bellows, so if you don't have the bellows, you can't use the reduction rings w/ the clamp on mechanism. Clamp rings are designed from 150mm and lower without using the bellows.

Thanks a lot Shervin!
Correct me if I am wrong

1. First of all Obox has two variant of work: Clip on solution (when mattebox fix directly to the lense) and Road solution (whet mattebox fix to the 15mm rods) is it Correct?
2. According to point 1 there are two kind of rings - Reduction Rings (metal or plastic ) (for fixing to 15 mm rods) and rubber Clamp Rings (for clip on solution) is it correct?
3. If you choose Clip on solution you just need a different rubber Clamp Rings (Clamp Ring 150mm-143mm, Clamp Ring 150mm-134mm, Clamp Ring 150-114mm, Clamp Ring 150-110mm, Clamp Ring 150-95mm,Clamp Ring 150-80mm) Is it correct?
4. If you choose 15 mm rods solution you need different (metal or plastic) Reduction Rings (Reduction Rings 114-110mm, Reduction Ring 114-95mm, Reduction Ring 114-80mm) and you need Bellows Ring 150-114mm to fix it. Is it correct?
5. Additionally Bellows Ring 150-114mm besides fixing Reduction Rings this Bellows Ring 150-114mm allow to fix 138 mm filters?
Is it correct?

Thanks a lot Shervin!
It was easy

Man, when we bought our O-Box, I called up the company and got someone on the phone and then drilled them with questions for 30 minutes before making our purchase...

And then we just ended up buying all the accessories for the o-box just in case there is a lens size or mount that someone may need. Because if you're running everything from DSLR lenses to RED zooms, you need everything.

And do you like your O-Box? I see a lot of people sell it.
