The Fujifilm H Mount Adapter G on the GFX 50S Medium Format Camera offers the ease of using nine SUPER EBC FUJINON HC interchangeable lenses, as well as the teleconverter lens that was developed for the FUJIFILM GX645AF medium-format film camera. The mount adapter enables you to adjust the lens aperture using the command dial on the camera body, and shoot with the shutter built into the lens, allowing a flash-synchronization speed of up to 1/800th of a second. And while the mount adapter limits the focusing mode to manual, the adapter’s electrical contacts communicate with the camera body, thereby creating, saving, and applying correctional data for each lens. The adapter also supports manual and aperture priority auto-exposure modes. In addition, it comes with a removable tripod seat, which maintains balance and prevents blurring when using a massive zoom lens.
