was provided with a K&F Concept K-Series 62MM MCUV Pro UV filter free of charge. It is delivered in a stylish silver-colored box with a K&F Concept print. In addition to the plastic box with the filter, you will also find a microfiber cleaning cloth. There is a QR code on its packaging that takes you to the K&F homepage. The filter is again in a plastic bag. I don't think that's a bad thing, as it prevents contamination before use. Before use, the glass is free of any fine surface scratches - I've had this happen differently with much more expensive filters. So far I have nothing to complain about in terms of functionality. I've always used filters as protection on my old Panasonic FZ1000 because you can't just swap the lens. (I've also had to replace the filter I used from time to time, problems happen quickly in the heat of the moment.) The filter can be easily screwed onto the lens and doesn't get in the way. It is often said that such UV filters affect the photos taken. I have never noticed this before and it is likely - if at all - only in an area that is perhaps just measurable but not visible. For only €11 I think you can't go wrong with the K&F filters. It's possible that some more expensive filters might be more scratch-resistant, €11 hurts far less when damaged than an expensive filter or even the camera lens. (However, I didn't intentionally test the scratch resistance - if anything turns out in one direction or the other, I will update the review if necessary.) For the moment, the filters get a full 5 stars from me.
