This fabric is not variable, it reduces 1.25 stops of light.

That should be a good distance to get a even light onto the diffuser and not have a hotspot.

I've heard the new fabric and frames are slightly larger than the old version. This fabric will likely be slightly too big for your old frame. Looks like Westcott wants to sell more new frames :)

Great question, William. The old version of Scrim Jim used 3/4" thick framing and the frames connected to each other using a tension fit. The new version (Scrim Jim Cine) uses a thicker 1" frame and connects using a positive locking system. The new system also has corners that are NOT built into the frame, like they were in the original version. The sizing of diffusion silks are not the same for the new version, as we standardized the sizing to what is common in the industry for the Scrim Jim Cine lineup.

The Scrim Jim Kit underwent changes in 2016 when it was upgraded to standard industry sizes, more mounting options, and more fabric options. This product is for the Scrim Jim Cine (new version) so please check your Scrim Jim version to determine if the sizing is the same. If you have further questions, please call Westcott customer support at 419-243-7311.

For a Scrim Jim Cine that is 6' by 6', a lot of people prefer to use two light stands with grip heads (Westcott part #1881) and Scrim Jim Frame Clamps (Westcott Part #1980) on each stand. If you want to use a single light stand, we recommend a heavy duty C-Stand with the same grip and clamp noted above as well as some sand bags for the base of the C-Stand.

No. Make sure you purchase the 42x72 inch silks for the original scrim jim frames. I made the mistake of ordering the 4x6 cine silk and it was to big.

The frames side components are combinations of 3 lengths of interchangeable tubes and connectors. The 6' x 6' frames are made up of 2-46 tubes connected to 2-22 tubes with the connectors adding the remaining length. The longest of the current Cine tubes is the 46 version. You could also build the frames with smaller components by ordering the frame tubes and connectors ala carte.
