Frame For 90MM Tilt-Shift Lens?

I have both the Canon 24MM Version II Tilt-Shift lens and the 90MM as well. I enjoy doing landscape panoramas, vertical, horizontal and diagonal as well, so I have the Rogeti frame for the 24mm, which allows for the body to move and the lens stays stationary. I have so far not been able to find a similar frame for the 90 MM. The 90MM I got refurbished as, shall we say, an impulse purchase because I use the 24mm all the time.  I understand that mostly that is used for things like product shots where the tilt function comes into play to alter depth of field. Is anyone aware of a "Rogeti-like" frame for the 90MM? Or is it that nobody uses it like that so that's why a frame doesn't exist? In any event, and I haven't tried it out yet, but I suspect the 90MM will make a nice portrait lens, even though it is manual focus.

Does not seem to be any. I find they are overblown, unless one is always stitching at 45 degrees.

I have had a 17 TS-E for over ten years and have rarely come across parallax problems. Once or twice I used the adjustable centre column of my tripod to move the camera instead.

I spent last summer doing a lot of diagonal shifting/stitching and the benefits simply did not make the additional steps worthwhile.

The 90mm TS-E is neat for portraits since you can use the tilt to define the plane of focus, and create more subject isolation than typically possible with an f2.8 lens. A Rogeti frame won't be required for this.

The effects of tilt is far more noticeable with the 90mm as opposed to the 24 or 17.
