Quick answer

Attach the H-Mount Adaptor G to your Fujifilm GFX camera by aligning the red dots, twisting to lock, and then mounting a compatible HC lens. You'll control aperture via the camera body and focus manually.

Why you need the H-Mount Adaptor G

The H-Mount Adaptor G lets you use SUPER EBC FUJINON HC lenses from the GX645AF system on your GFX camera. This opens up nine lenses and a teleconverter, giving you more creative options without buying new glass.

A key trade-off: focusing becomes manual only. The lens aperture, however, is controlled conveniently from the camera body's command dial, and the built-in lens shutter remains functional.

Step-by-step attachment guide

  1. 1. Prepare your camera and adaptor: Turn off your Fujifilm GFX camera. Remove the body cap from the camera and the rear cap from the H-Mount Adaptor G. Inspect both surfaces for dust or debris. Common mistake: forgetting to turn off the camera can cause communication errors. Always power down before attaching or detaching adaptors.
  2. 2. Align and attach the adaptor: Match the red alignment dot on the adaptor with the red dot on the camera body. Gently insert the adaptor and twist it clockwise until you hear a click. The adaptor should sit flush with no wobble. Checkpoint: if the adaptor does not click into place, do not force it. Remove, realign the dots, and try again.
  3. 3. Mount the HC lens: Align the red dot on the HC lens with the red dot on the adaptor. Insert the lens and twist it clockwise until it locks. You will feel a positive click. Common mistake: twisting the lens too far. Stop as soon as it clicks; overtightening can damage the contacts.
  4. 4. Set up the camera for manual focus: Switch the lens focus ring to manual (M). On the camera body, ensure the focus mode is set to manual. Use the camera's command dial to adjust the aperture. The lens shutter will fire as normal. Checkpoint: aperture changes via the command dial may feel unfamiliar at first. Test a few shots at different f-stops to confirm correct exposure.
