The combined updater file released today is very nice because the single package works for all IQ-series back, whether IQ1, IQ2 or IQ3, CCD or CMOS. Credo users, however, can’t make use of this combined update.
Located instead on the Mamiya Leaf firmware update page is a version that your Credo will recognize.
