## Long description

The Viltrox DG-GFX 45mm extension tube for Fujifilm GFX medium-format cameras increases the lens-to-sensor distance by 45 mm to enable closer focusing and greater magnification without adding optical elements. This single 45 mm tube is designed to fit Fujifilm GFX-mount bodies, specifically developed for use with FUJIFILM GFX50S and GFX50R, and maintains electronic connections to preserve autofocus and exposure communication with compatible lenses.
Advantages
The extension tube allows macro and close-up photography by increasing reproduction ratio while avoiding additional glass in the optical path, preserving original lens image quality. It supports electronic contacts with a pure copper pin and metal interface for reliable signal transmission, enabling autofocus and aperture control with supported GFX lenses. The tube can be used alone or combined with other compatible extension tubes to achieve different magnification levels.
Suitable for
 Product photography and small-object detail shots
 Nature and insect close-ups
 Texture and material detail imaging for catalog or archival work
 Creative macro work with Fujifilm GFX lenses that retain AF and exposure control
Key specifications
 Extension length: 45 mm
 Mount type: Fujifilm GFX mount (for medium-format bodies)
 Electronic contacts: copper pin contacts with metal interface for signal transmission
 Compatibility: designed for FUJIFILM GFX50S and GFX50R and compatible GFX-mount lenses
 Construction: metal mount for durability and secure fit
How to use
Attach the extension tube between the GFX camera body and a compatible lens by aligning mounts and locking the tube in place as you would with a standard lens. Confirm electrical contacts engage to retain autofocus and aperture control. Compose and focus as usual; note that effective minimum focusing distance will be reduced and magnification increased, which may require manual fine-tuning of focus or use of autofocus depending on the lens and subject. If combining with another extension tube, ensure secure connections and re-check focus and exposure settings before shooting.
Usage recommendations
Use a tripod or stable support when shooting at high magnifications to minimize camera shake, and consider additional lighting or smaller apertures for increased depth of field. Verify compatibility and AF performance with your specific GFX lens model before critical assignments.
