Review: Decent bit of kit - Great addition to my kit for car photography
Review: Good filter, but potential issue at full zoom. - Update: K&F have been in touch and sent me the X Series filter that does work fine at all focal lengths. Much better customer service than I originally received. I’ve changed the rating to 4 stars, as this filter did work really well while not at full zoom, and may not cause any issues at all to smaller lenses. It’s well priced and fits and works well. I just wish there was an acknowledgment of the known issue at higher focal lengths in the description to better inform customers. Original review: Very disappointed. The filter does work well, as long as you don’t use your lens at full zoom. Obviously while you’re out you definitely want the ability to shoot at full zoom, 200mm for me, but you can’t as the photos are completely blurry. I did contact K&F for assistance, their reply was that the issue is because I bought the K-Series. And if I now spent more money and bought the X-Series it “will likely eliminate the focusing problem you’re encountering.” As a gesture of good will they have offered a 20% discount, but I don’t feel that’s good enough. There was nothing on the product description to say there is a known issue with this filter, and I don’t think I should be out of pocket any more than I already am. Because of this I couldn’t recommend this filter. Two quick, unedited photos attached showing without and then with the filter at full zoom. Photo is unusable!

### ⭐⭐⭐⭐⭐ Doesn't work on zoom lenses
*by V***M on 13 August 2025*

Edit: I have upgraded from 1 star to 5 stars to reflect on the outstanding customer service I received. I had a problem with the filter I received but the company got in touch with me and offered me a refund, replacement, or an alternative filter (which they despatched almost immediately). The filter they sent me works beautifully. Things go wrong sometimes and I was very impressed with how well and how quickly they responded to this. I would have no hesitation in purchasing from the again Fits easily and turns easily, Works ok for wider shots, but on full zoom the image is unusable. I took two shots with a Nikon Z6 and the 28-400mm lens, shot on manual at 400m, F/8, 1/320s, ISO 100 The first one is with no filter and the second with the K&F filter. It's cheap so not worth returning but I will need to buy something that works at 400mm
