This sunshade is made solid and does what it should. Against any play on the Panasonic lens, holds scattered light and gives the front lens protection. After a month or two to me has not yet realized what the manufacturer makes the circumstances, at the back so finely mill out these vents. Approximately only because Leica pretending this fashionable trend? Well then! For cooling that can hardly be imagined, the lens in any case is not hot when in use.
