Hi Guys,
The x Stuff is great! As mentioned above the Easy Riser adapts the Red One baseplates to the Scarlet/ Epic cameras; both the original ones from Red and the newer Element Technica Hybrid Plates. The originals were either 19mm studio or 15mm studio; the hybrid could be adapted for both by changing the front and rear brackets.
You are correct the O-Box is native 15mm LWS. It can be adapted to either studio rod standard; there are two ways to do this:
OConnor Solution:
15mm Studio you need the 15mm Studio Adapter C1243-1119 AND the O-Grip Three System Rod Bridge C1244-1002
19mm Studio you need the 19mm Studio Adapter C1243-1118 AND the O-Grip Three System Rod Bridge C1244-1002
The advantage to this route is that it allows for O-Grips to be added to the left, right and center of the rod bridge for a lower center of gravity handheld rig.
This disadvantage is that you have to remove the 15mm LWS bracket that comes on the O-Box using two 3mm captitive Allen screws and replace it with either studio adapter and then mate this with the rod bridge.
Third Party Solution:
Plug and play adapter from Abel Cine part AB-1515

Plug and play adapter from Abel Cine part AB-1519

The advantage to this is that you do not have to remove the native 15mm LWS bridge on the O-Box, it just "plugs in" and adapts to the studio rods. These can also be used to adapt most any native 15mm item (mattbox, follow focus, etc.) to studio rods so they serve more than one purpose for various rod supported accessories.
The disadvantage is that when using O-Grips they can only be mounted to the mattbox itself unless the Three System Rod Bridge is attached to the rods as an extra piece.

Hope this helps-
