As a lens cap it caps a lens. That's the positive. The downside is that this cap is difficult to remove if you have a lens hood attached. Also, like many of Oly's accessories, it's cheaply made. That fancy chrome-rimed center makes Oly's name look good but it's cheaply glued on and will eventually fall off. Unfortunately at that point it becomes even more difficult to remove. At least they only charge $7 for it but I'd recommend buying a third-party center-pinch cap instead
