There's two ways of doing business - high margin low volume and low margin high volume. I think it's pretty obvious what they're going for at that price-point. As a higher end DSLR shooter, Black Magic nailed exactly what it takes to get me out of that market. I'm certain this is the case for many others. I see literally nothing else on the market for $5k that even comes close to this offering. Plus, the 4k version at $3k is an insanely good offering as well. I gotta say, this camera is the most exciting thing to happen in the camera market for guys like me since ... ever. Black Magic - thank you for knocking this out of the park.

I'd think twixtor might make this list

Well, I shoot with a mark II so I don't usually have to worry about adding light. But, in a situation like this, I will often just bounce light off the ceiling. It's a very lean way to evenly light a room. I just use a flood, color it to daylight (since there likely will be natural light as well) and point the light straight up. There is certainly a balance of how high you want the source / what part and how much of the ceiling you want to hit. And with kids - make sure you sand bag those puppies and tape your wires. You'll also want make sure that your source isn't so low that it leaks unbounced light anywhere - so have some black wrap.
