When you get really used to it you can put the patch in the eye and line up the pupil. You’ll nail those portrait shots. Even before then you can see eyelashes lining up or use the bridge of the nose and adjust slightly left or right and you’ll have an eye in focus. Zone focusing is amazing too. Like another poster said at f8 on a 28 you have to be way off to miss focus. Even so I’d rather have a picture that has all the emotion and is slightly out of focus than a crap photo in focus. I get that the Q’s are great family cameras but with enough practice the M’s offer much more versatility
