The panel is light, rigid and not lead even at wide-angle focal length to the darkened corners. They snapped a reliable and can "upside down" are attached to the lens so that it can be stowed away together with the camera, without affecting the overall length (the lens) noticeably increases. Important: regardless of whether in work or in transport position, the sun visor (the visor so remove previously) will lead to shadowing the bottom right, as soon as you use the built-in flash. But that is in almost all cameras so, so I prefer not release any point.
