You're welcome "tocayo".
Back in the film days (when I could afford medium format photography) I played a lot with CF Hasselblad lenses on field cameras fitted with 6X9 roll film holders and even 4X5 sheet film.
If I recall well, all CF lenses project a circle a few mm's outside the 55X55mm square of the Hasselblad V film backs. All lenses, especially large format lenses increase usable image circle by stopping down. CF lenses not so much though. The CF40mm is the lens with the smallest circle barely covering the 55mm square.
I've never owned a Flexbody but after using view and field cameras I'm sure it's way easier. As a matter of fact, I used a Tachihara field camera fitted with a home-made back for the Hasselblad A12 backs. I bought a screen adapter fitted with an Acute-Matte. This adapters were meant to be used with Hasselblad's SWC cameras. I also bought the reflex finder for it. Even on the Tachihara, focusing was a breeze.
To use a Flexbody for stitching must be super awesome because you move the back up&down, not the lens. This is the safest way to avoid parallelism problems when photographing near and far objects in the same view. Since PS CS4, the Photomerge plug-in does a fantastic job avoiding parallelism problems by intrinsic cut-offs but sometimes all fails and you have to fix problems by hand.
A wet dream is a Flexbody with a Leaf 56X36 back to stitch 2 frames for fast, perfect and easy 56X56 squares! I know, it is a fetish, but so what?

PS "tocayos" is a word in spanish for 2 or more people sharing the same first name.
Flexbody! ... moving the body instead of moving the whole camera, good idea! I could just use rise and fall movements to get the up & down extra images...
Do the Zeiss lenses for Hasselblad V have an image circle large enough to "cover"/support such (small) rise and fall movements? ... ... in my case: yes, as I anyway use a 49x37mm crop sensor, it would be like just "scanning" different parts of the full 6x6 frame with my small sensor ... but focusing doesn't look easy with flexbody isn't it?
In fact I should use the tilt/shift adaptor ? (would be the same, just moving the lens instead of the back, still without moving the camera position on the tripod)
thanks for the great idea
(before that I was thinking of using "extension bars" to set the rotation center over the lens, like with pano photo ;-) to get rid of the stitch-images-with-different-perspectives problem)
