Had a think about this. The 2x2 diffusion paired with a light like the Wasp 100s could make a pretty efficient self contained kit.
One fairly common use case that comes to mind is interviews, many times I am working with little or no crew and have the subject for a short period of time (and limited space in some cases. A 2x2 could be combined with the light into what is essentially a single unit that cuts footprint and setup time.
There are other issues I'm curious to see if they are resolved when these are in the wild but there are applications for this IMO.
First thing I would say is to balance for the tungsten lights. You want to give yourself enough room to fiddle in post which you aren't going to get if "everything is yellow". Secondly. Gel Gel Gel. Do not rely on post to produce the color that you need. Build the look you want in front of the camera. At that point you have 100% control of the image so why give that up? Your end result if you rely heavily on post is reliant on the talent of your colorist and how much time (and money) you have to do spend.
The original C100 was a really great camera to use. Shot a doc on a couple of them with very little issues. They seem to have addressed all of them with this model. Would probably pick this up as a "daily" shooter over a DSLR now. 4k isn't a big deal for most things. HD and a quick turnaround are what most projects call for. Looking forward to getting my hands on this.
