Affinity Photo 1.5.1 and 1.5.2 beta 4 opens RAW files for the new medium format Fujifilm GFX which is great. But the raw image is shifted left by 466 pixels leaving a black part on the right side of each image. I know that this camera is not listed on the support camera list page, but it would be great to have a fix. RAW files from an early production model can be found here: https://www.dpreview.com/samples/2109992390/fujifilm-gfx-50s-first-shots
One user of Fujifilm's Facebook group for the upcoming medium format Fujifilm GFX 50s posted that with Affinity Photo you can develop the RAW files for this camera. I have tried this and it really works. Great!
