Robin, we bought the color viewfinder with the camera. Our crews were so used to the Sony color viewfinders on the F900’s and F900R’s. The color viewfinder is OK. It is not as good as the Sony’s. Our crews are getting used to them, but it is an on-going process. We did not consider the B&W’s. One other thing about the 3100’s, there is not a LUT in the eyepiece. You are always looking at a Flat Film Rec image. This is different from the 3700, in which you can apply a LUT to the viewfinder.
