The GFX 50R isn't the only new camera Fujifilm is unveiling at Photokina 2018. As rumored, the company has also introduced the GFX 100, a ridiculous 100-megapixel medium format mirrorless shooter. Fujifilm says that its GFX 100 will be the world's first medium format and mirrorless camera with a 100-megapixel sensor, and it will have in-body image stabilization and 4K video.
