So I picked up an rz pro2... nice. I also recently got the rz tilt & shift gizmo. I have a complete rb67 pro sd system, that I still love for various reasons, and I wanted to adapt the rz t&s gizmo to the rb. I noticed that the lens caps are very robust, so... I decided to try making an adapter. What you see in the one photo is the t&s adapter mounted on the rb via my adapter, with a 210 rb lens on front. In the other photo you see the adapter itself. It is very strong and *professionally manufactured* To make the adapter, you just superglue a body cap to a rear lens cap and bore out the middle on a lathe. Presto. Bear in mind that you will lose infinity focus with this adapter (if you didn't already by not using rz short-barrel lenses). But for my macro purposes, it's just the thing. Next I am thinking to adapt the t&s gizmo to my 645 afd. Pardon the cellphone photos.
