What is wrong, is the value for money. The pricing policy of Olympus in terms of accessories, is more than questionable. I'm used to the prices Accessories Canon quite a bit, but still tops Olympus. In the anti-reflection ring is an approximately 3 grams heavy black plastic part, whose sole peculiarities consist of the thread and the Olympus print. To charge for it thirty euros (the cheapest supplier), in my opinion borders on usury. The production costs are likely to amount to a few cents.
Soon is with me on the purchase of an external underwater flash, including mounting rail and arm. To the original accessories from Olympus I will here make a big bow. From other reviews I know that other clients keep the prices Accessories Olympus to be excessive and to look for cheaper alternatives. The fact that Olympus with this pricing policy is doing a favor, I doubt it.
