Hi, Phil. Thankx for your help. I thought i' d replied your post last week, but something i did, didn't post it.
Well, I'll have the camera one day before i shoot, and this material will be transfer to film. So, since i won't be able to make any test with it, I thought about going to the location and test (or guess), with a still digital camera what is the mininal ISO necessary to get any information there. That's why i needed the information about the gain. Since we'll be transfering the material, noise isn't what i want. I'll try to use it just the extremely necessary.
