Fujifilm MCEX-18G and MCEX-45G on GF Lenses
Revised 2023-03-16 by Bill Claff

Introduction

Fujifilm publishes information on the effect of using the MCEX-18G and MCEX-45G on a variety of lenses.

The table below is the same information which I have supplemented by computing some additional values of interest.
Note that some of the computations are approximate because internodal distance at infinity is not known.
