    Does a firmware update require len/camera to be AF microadjusted again

    I have been doing AF microadjusting with both my Canon 5D Mark IV and 1DX II for quite some time. I even share an article with my clients about it. One client asked me today if upgrading the Firmware requires AF microadjusting again. I suspect it does, but not completely sure. Can any of you...

    Shaggy Mane Mushroom Family
