18 mm G-Mount Extension Tube
This 18 mm macro extension tube fits Fujifilm G-mount lenses and GFX cameras. It increases maximum magnification and shortens the minimum focus distance of the attached lens. The tube has an 82 mm diameter and weighs .38 lb. It is designed for photographers who want closer focusing without changing lenses.
Bayonet Mount Installation
The tube mounts directly between the camera body and a compatible G-mount lens using the standard bayonet. No tools are required and electronic contacts pass through for aperture control and EXIF data. The main issue is vignetting or loss of infinity focus when the tube is used with lenses not designed for close-up work.
Optical Limits of Extension
Adding 18 mm of extension reduces the maximum focus distance so infinity focus is lost. Light transmission drops because the effective aperture narrows, requiring longer exposures or higher ISO. The tube does not contain optical elements so image quality depends entirely on the lens used.

Questions about this item
How can I verify the MCEX-18G is working correctly after attaching it to my GFX camera?
The tube should sit flush between the G-mount lens and body with no light leaks, and the camera will display focus confirmation when the subject is within the new minimum focus distance.
What comes in the box and do I need to buy anything else to start shooting macro?
The package contains the 18 mm extension tube with G-mount contacts; you only need a compatible Fujifilm G-mount lens and GFX camera body, both sold separately.
Which version should I choose if I want more magnification than the 18 mm tube provides?
The 18 mm length is the only size offered for this G-mount model; for greater magnification you would stack additional G-mount extension tubes if available.
