I am not a professional, but I know my way around a bit. For the semi-professional use, I have my wife bought a Lumix-FZ1000 and wanted to see the price range 10-40 a protective filter. The offer of mega photo for 11 was striking to me, because the next offer was> 30. I thought I could not lose much and resorted to. Direct hit! Mechanics fit, threaded neither lightweight nor too stiff, nothing wobbles ... Appearance: I have about a dozen images pairs shot - daylight, low light, flash and could only with much effort on the PC and in the 1: 1 representation notice a slight loss of sharpness. My logic: in> 99% of cases, this loss is not important to me and the rest of <1% of the time I can unscrew the filter. The professionals and photo purists will comment on here that I do not have then the UV filtering. That's true, but I do not walk into the areas of perfection that would require these fine nuances. So for robust everyday my full recommendation Only one caveat: the filter was previously only one in use (about 1000 trips) and I can say nothing about the long-term stability.
