Low light and the HVX
 

So from my experience so far the HVX gets really noisy in low light situations. I've tried the Cine V and it helps clean up some of the noise but it's still there. I have also over lit a scene ( being mindful of blow outs) , only to time it down later and that seems to work even better. The only thing I haven't done is use both Cine V with over lighting AND time down later. I use the Redrock M2 adapter and that cuts my exposure by about a stop and a half to two stops. So I have 5to compensate for that anyway before I shoot. So if anyone wants to purposely under light there scene using either the HVX alone or with the adapter(any adapter really) you should light to get a tighter grain structure in your picture and then work on it in post. Or if you have the budget do a professional color correction.

Just my experience if anyone has anythign else to add feel free.
