MCEX-18G WR and MCEX-45G WR expand the range of macro photography. Connecting the macro extension tubes to any GF lens allows macro photographs to be taken at a higher magnification ratio. Depending on the magnification ratio required, the photographer can select either the 18mm or 45mm tube. In particular, connecting the GF120mmF4 R LM OIS WR Macro (half-macro) and the MCEX-45G makes it possible to take photographs with life size 1:1 macro.
