Shortening the Minimum focusing distance of FUJIFILM G-mount lenses, this MCEX-18G WR Macro Extension Tube enables you to achieve a greater maximum magnification for close-up shooting. This 18mm-long tube enables macro-like performance for lenses not otherwise able to focus closely, and since the tube does not contain any optical components the image quality of the original lens is maintained. Additionally, integrated contacts maintain full autofocus and auto-exposure functionality.
