Casio Exilim Pro 5.0 mega pixels 5x zoom mpeg-4 movie EX-P505 camera and video

Casio Exilim Pro 5.0 mega pixels 5x zoom mpeg-4 movie EX-P505 camera and video recorder. Comes with battery and charger as well as cables and turns on. I'm not sure what the black circle is that comes with it but I'll include it. It seems like it may be a lens but had no glass but it's just an added accessory. The camera video recorder itself is works perfect.
