Ronin 4d sigma 28-70 L lens,  had a few issues now the calibration goes and the lens just goes out of focus and re calibrating makes no difference, have to switch to MF.

Fyi had this with flex and without.    I rolled the firmware back and now the problem seems to have gone away, however i now have all the issues of the Ronin not remembering settings.
