Hi,
I don't have a 23 in Cambo mount but do have a 32HR if you are interested. I have the 23 for my Phase One XT and use it often for my architecture work but there is only 3mm movement on it, if you weren't aware of it. Its an expensive investment for almost no movement but I need it for my work.
I've posted my lens for sale if you are interested in in. Pristine condition. I am looking to get the XT version.
