If you are recording a match in the distance, set to manual and focus on infinity. Auto focus was probably "hunting" in the dark conditions.
So I ran into a bit of a focusing issue this past weekend. It only came up in the 2nd half. I did use the zoom more in this game, so I don't know if it's related to zooming. The 2nd half, the image would be sharp for a few minutes, then just go out of focus for a few minutes, then come back in, then go blurry again. The blurry was still viewable, but obviously not the best.
What I normally do is set up and then just let it record. I haven't had this happen before, so I don't know what was the reason. Was it, for example the fact that it was cloudier that day and starting to get more dusky? Was it b/c I was zooming in more than usual? And if anyone has any suggestions to avoid this, that'd be great. Like I have had a bit of a struggle with the facial detection, so I haven't been using it, but maybe would that have helped? (The issue is getting it to pick up on my son. and sometimes, it may pick up on him at first and then switch to someone else, so I have been a bit hesitant to use it)
Any comments, suggestions would help. Thank you!
