VG-C4EM Battery Grip for Sony A7 S3, A7R IV & A9 II MSLR Cameras

These new grips have a plastic push lever on top of the grip which when inserted into the camera gets pressed down and extends out the side contact pins. When you go to remove the grip this top lever gets stuck so the side pins stay extended making it impossible to remove the grip. This is not something you want to see when it's mounted inside a $6500 Sony A1. After a bunch of jiggling it finally released.
