After faster delivery through Amazon I immediately screwed the protective filter on the lens 14-45 3.5-5.6 OIS Panasonic GF1 my. The protection filter is thus compatible with more than the above mentioned products. For safety's sake always look in the camera instruction manual and / or the lens. The filter is easy and I think the use is important because it protects the front lens. The protective filter is transparent and affect recordings in any way, so that it can remain on the lens permanently or should. The lens cover may still be attached. Processing I consider quality. I highly recommend this very protection filter without limitation.
