Just got a zs200, nice little camera. I was especially happy about the 4k burst mode. Was using 4k burst ss today filming a horse event and the video looked fine but many if not all the pics were very grainy & fuzzy. Some parts of the pics in focus other parts looked very bad. Was wondering if it was a setting or something I was doing wrong or just the limitations of the camera, 1" sensor, auto focus, etc. It's a great way to take photos but not with my results today. Would very much appreciate and help. Thank you.
