A good protection filter for these cameras, in my case, the Lumix DMC-FZ200. The glass filter is flawless and affect recordings in any way, so that the filter can remain on the lens (and should!). I think this filter for extremely important to rule out damage to the expensive lens. Although this part is not necessarily one of the specials, I hold the filter at the price for a fair deal. Therefore, from me a clear recommendation.
