This is a great back but not quite as good as my Aptus 75S so it rarely gets used. I've decided to sell this and, down the road a bit, my Aptus 75S, and move to the Hy6 and eMotion 75 which will let me use both the RZ and my Contax 645 cameras simply by changing adapters. These backs go for $7k and are not that easy to find. I'd like to get $6k for mine.
