Extension tube for Fujifilm G mount

The FUJIFILM MCEX-45G is a 45 mm macro extension tube designed for Fujifilm G-mount lenses and GFX cameras. It fits between the camera body and the lens to increase maximum magnification and shorten the minimum focus distance. The tube maintains electronic communication so aperture control and EXIF data transfer continue to work. Its black finish matches the GFX system aesthetic.

For close-up work with GFX lenses

This accessory suits photographers who want greater magnification from their existing G-mount glass for macro or product photography. It is not for users of X-mount or other lens systems, as the mount diameter and electronic contacts are specific to the G format. Buyers who need variable extension lengths or a set of multiple tubes should look at other solutions.

Fixed 45 mm extension length

The tube provides a single, non-adjustable 45 mm increase in flange distance, which determines the magnification gain and the new minimum focus distance achievable with each lens. The 82 mm diameter and 1.77 inch thickness define how it balances on the camera. Compatibility is limited to Fujifilm G-mount lenses and GFX camera bodies.

Questions about this item

Which extension tube length should I choose for my GFX system?

The 45 mm tube provides a moderate increase in magnification while keeping the working distance usable for most close-up subjects.

What does the 45 mm length actually do when mounted on a G-mount lens?

It shifts the lens 45 mm farther from the sensor, which raises maximum magnification and reduces the minimum focus distance of the attached lens.

Does the G-mount connection preserve electronic aperture control and EXIF data?

Yes, the tube maintains full electronic communication between Fujifilm G-mount lenses and GFX cameras, so aperture control and EXIF recording work normally.
