A few Oconnor O-box questions, ie) nuns knickers and rotating stages

[Vladimir Druts]

I'm purchasing an O-box and wondering if the Genus nuns knickers will work with it? I heard no, anyone know one that will?

Also I heard there is an issue with rotating the back filter if you have a follow-focus as well as 4x4 filters? Is there an extra attachment required?

Anyone know how one would adapt the obox to Canon L or cinema lenses?

For the O-Box with a variety of Canon mount glass, I'm using the following pieces:

O'Connor Bellows Ring (C1243-1117)
O'Connor 114-110mm Reduction Ring (C1243-2171)
Chrosziel Flexible Step-Down Ring (AC-450-22)

Working well for me.

No issues with the FF but if you are using 15mm rods the rotating stage will run up against the rods if the rods protrude past the mount on the O-Box. If you can get the O-Box sitting right on the end of the rods the rotating stage can spin the full 360. Certainly can be a bit of a hassle. No issues with the FF that I've experienced.

Cheers

Thanks Sean.

Depending on the lenses you use, you might also consider the Chrosziel AC-450-20 110:75-98mm.

I have the AC-450-22 and it's too small for my new Canon EF 24-70mm f/2.8L II which uses the wider filters.
