Upgraded from 220.127.116.11 to 18.104.22.168 firmware, now my normal AF mode does not work!!! The i.AF mode seems ok, but very slow. I've looked all over for a way to downgrade the firmware, but can't find a way to do it? Cleaned lens, AF window, etc... nothing blocking it. I've googled and not found anyone talking about this... help?
