I'd like to force myself to shoot panoramic (2:1 or greater) shots occasionally. It would be nice if I could do this in camera. I'd prefer it to be RAW. It could be as simple as frame lines in the viewfinder.
I don't need the camera to do the actual cropping, but if it could apply the crop in metadata to the raw file, that would be nice (Similar to the digital zoom on the Lecia Q's). I just want to force the panoramic perspective when shooting. Basically just adding black bars or framelines to the top and bottom of the image in viewfinder.
The main point is that the viewfinder shows the panoramic field of view for composition.
Similar to what the medium format FujiFilm GFX50R will do. https://fujilove.com/shooting-panoramas-with-the-gfx-50r/
