Hello , This may seem a silly question but does the canon 90D have some sort of function where it can put manual focus to sleep. I have 2 canon EF/STM lens and 2 EF/USM lens. and the same thing is happening with all 4 lens.
I manually focus on the subject i am going to take a photo of and then i take the photo.
When i turn the focus ring again to do something else it does not re-focus.
I found that if i half press the shutter button the focus ring will work as it should.
I have timed how long it takes for the the focus rings on my lens to stop working.
If i focus on something and count to 10 then turn the focus ring it does not alter the focus.
As i say it does this on all 4 of my lens.
