On my new Canon T6s/760d with 18-135 STM lens, I just noticed that in AF mode, when I hold the shutter button halfway, if I turn the focus ring on the lens, it does affect the focus!
I preferred to stop doing that, not knowing wether or not it could be dangerous for the lens (of course it didn't seemed as I was forcing any mechanism, since this ring can turn continuously on this model, and doesn't seem to be directly linked to the AF mechanism).
But I am just wondering why it is behaving like this ? Is this intentional ? If it's not can it be dangerous to do that?
