I am a newbie photographer looking for a digital camera to shoot sports action at night. My kids play softball (infield) and baseball (outfield), typically under the lights. It needs to have a good zoom and burst mode. I currently own a Sony DSC-H400 and it is not up to the task. Its “burst” mode seems like one shot per second and the viewfinder goes black between shots. Night shots are either fair resolution but blurred action, or sharper pictures that are too dark. I was hoping to keep the price under $700 but don’t know how realistic that is. Can anyone help a sports dad out?
