If true, there may be some carry-over to IQ1 MFDBs. IQ1 and IQ2 are closer related than realized, as some previous firmware updates added functionality to IQ1 that initially were disclosed as only applying to IQ2. This may be because there is just enough differences that uniform application can't be guaranteed.
Right now, my DF is pretty solid with the IQ180. As long as a stable, or more stable platform is provided by the XF body----and I get substantially better AF performance/accuracy, I'll be happy.
Are there features or is there something required on the IQ1/2 series by firmware before they can be used with the XF??
It seems we lose the ejji nuclear generator battery, so I guess the smart move is to make sure all batteries are updated to the new 3400mah capacity batteries.
