It looks very interesting, if the objective of highlighting the refined cut and cover it back together folds into itself when switched off. The wow factor is inevitable. But that is not the only positive side of this cover: it is firmly connected to the lens, not dangling around in front of the lens and can also be kept in mind, if you set the camera in motion. That he is not supplied as standard, is certainly the fact that other resolutions can be screwed in front of the lens. Then the conventional lid would be more appropriate. In any case, this cover solution is ingenious and thoroughly recommended. The refined technology justifies my opinion well worth the price.
