A long-awaited accessory for M43 lenses

1. Usefulness: long we have to wait on such a thing as quickly ready to fire and pocket fit makes our small M43 cameras as a Compact. It would have also earned five stars if it was (the Zuiko 45mm for example) and not only on the super compact Zuiko 14-42 work on other lenses with the same filter thread. But this is not so. Since the opening and closing of the lid are carried out mechanically during the extension and retraction of the lens probably expected such lens cap only with lenses which have such characteristics.
2. handling, processing and price: The automatic lens cap is screwed quickly and contributes only to the 3mm. The two projecting beyond the lid handle to screw disturb neither optical nor in handling, as it does not extend beyond the lens. The thing itself is pure plastic, the Irsisblende yet but makes the impression as if they -if closed-at least as much as withstand the aperture in the compact. About the price of this simple piece of plastic you should not have to think too long rather, innovation happens to have its price.
