My Panasonic GX-7 was doing fine and I took a few shots today and when I tried to remove the SC card,an Optima 4 GB card it was hard to remove. The little movable tab on the side was broken off. When I tried to put in another card it would only go in about a third of the way in. As you can see in the picture there is a tab sticking out of the inside wall of the card holder. I have no idea why this tab is present .It looks wrinkled but that is the reflection off the wall of the card holder. I have no idea why this happened as the camera was not dropped and the card clicked in without incident. I did have a GF-5 which had a similar problem and they replaced the camera. I can't see any tab in the replacement camera. Does anyone have any idea what is going on.
