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 shed some light or experience on AF microadjusting and firmware upgrades? Thanks a bunch. I did not find much on the web so far, so if you have a link, please share it.
Here is my article on how I do it and my sharpness has been the best ever. These calliope hummers were done with a Canon 1DX Mark II and a Canon 600mm III with 1.4x.
