I bought the set with filter adapter, UV protection filters and automatic cover. The price of about 30 euros for the three part I find appropriate to filter adapter and filter there is nothing to complain about. The automatic lens cover is a matter of taste, I have not bother me at the snap lid of the original version, but the automatic has been its advantages, even if it means the camera is already clearly thicker. To install the cover: There is also of useful guidance on youtube. I immediately tried immediately after the assembly, as the lid behaves when removing. Here you have to watch something, because the plastic frame twists like when you try to turn it too far forward. To mount the filter assembly: There are instructions in the manual. As a tip should be mentioned here that the original thread protectors can turn much easier than you might think (especially if you have previously installed the lens cap). The ring does not hold too tightly, then he can unscrew itself quite easily.
