Re: EF-M Adpter: Focus problems

I have the same problem.
- M6 II
- Viltrox EF-M adaptor
- Canon 50mm f1.8 STM
- Camera settings: One Shot AF, AF Method is the square (don’t know its name), - Continuous AF disabled
Sometimes the lens won’t focus correctly when I press the focus button. You can hear the lens being jolted electrically and then the focus indicator beeps but enlarging the image shows it’s not in focus. Yet on other occasions it works perfectly. The Canon EF-M 32mm/1.4 and 22mm/2 work perfectly all the time.

I’ve tried other focus settings like continuous AF but the fault is still there.
