Get the EX-1R. I just shot with both the 1R and the NXCAM last weekend and the picture is much better out of the EX-1. Also, the lens is much easier to work with and the manual iris has stops instead of just spinning the ring indefinatley. The EX-1 wins hands down in picture quality, especially in low light.
