I first heard about the 24x65mm panoramic format when I bought my Fujifilm GFX50S a few years back. The digital medium format camera is able to shoot in 24×65 cropped mode whilst keeping the raw file intact and uncropped. I thought it was fun to shoot but I didn’t really commit to the format that was produced in-camera and I often found myself changing the crop afterward.
