I usually shoot photos of my dogs and/or food photography, but the last couple of days my shots look as though the objects are moving really fast when they're completely still. I've attached a photo to show what I mean as I'm not sure I'm explaining it properly. I'm not sure if the settings were somehow changed or if there's an issue with my lens or camera. I've tried resetting the settings on the camera and I'm still having the same issue. Any ideas what may be causing this?
