    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* :tongue:

    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.

    I'm curious as to why you need an adapter if you have a Pro SD body. Since the Pro SD has the same size opening as the RZ, the t&s should mount onto the SD body just fine without any adapter.

    How are you cocking and firing the lens with the adapter (I assume you are using the mirror up cable release socket on the lens and turning the pins on the back of the lens by hand)? Personally, I wouldn't trust super glue with the lens hanging on it. I would have used epoxy.

    Hi Max, the rz t&s adapter doesn't fit the rb, it has basically the same rear mount as an rz, i.e. two pins that prevent mounting on the rb. And I don't care to permanently modify the t&s adapter, nor my precious rb :wink:

    The super glue I used is epoxy.... super glue is just the company / brand name:

    Note to anyone thinking of using this Advanced Technology with other cameras: if your camera doesn't have bellows focusing, then you will of course need helicoidal focus on the lens... and AFAIK the only rb/rz lenses with helicoidal focusing are the 100-200 zooms. So in other words this doesn't seem a good general solution for a 645, though enterprising minds will find a way....

    Okay, just de-pinned the RZ t&s adapter, and indeed it works fine on the rb now with no other adapter. It also still seems to work fine on the rz. So... thanks for the tip!
