MCEX-18G and MCEX-45G on GF Lenses
Prepared 2020-03-25 by Bill Claff
Fujifilm publishes information on the effect of using the MCEX-18G and MCEX-45G on a variety of lenses.
information (a PDF) has recently gone missing.
(Formerly at www.fujifilm.com/products/digital_cameras/accessories/pdf/mcex_02.pdf.)
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.
