thank you for your comments. I do own a 6x12 Calumet Back for my 4x5 and I never took it into the field. Nevertheless, I never felt missing a panoramic shot. I do always carry a set of passepartouts (cut black/white mats 4x12cm, 6x12cm, 9x12cm, 4x5") with me. They fit onto the ground glass on demand, but are usually used as a framing aid before I even unpack the camera. For me, the 6x12 back simply does not add any functionality but weight. There is a world of panoramic frames that can be assumed on a 4x5 sheet. And you may even revise a framing decision in the darkroom afterwards. If I wouldn&#39;t use my 6x12 back occasionally for architecture (when I usually take the big box in the car), I would have sold it already.
But it&#39;s just my personal point of view.
