K&F Concept 37mm Circular Polarizer Filter,18 Multi-Coated Optical Glass Circular Polarizing Filter Ultra-Slim for Camera Lenses with Cleaning Cloth (K Series)

The filter reached me intact. It was just like shown on the page. Tried the filter on my dslr and the result obtained was good. K&F Concept brand is very good and reliable.

Works well but not mind blowing. Good for those on budget

A pretty good CPL filter. I like the quality, but there is one downside - lens cap no longer fits :(

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

Dobry produkt

Disappointed. Not as described. It just mskes a shade on picture.

Like, the headline says, this IS technically the low-level when it comes to K&F filters... however, it performs wonderfully. For me, I had no issues using it and noticed no lack of detail or focusing ability. If there WAS any detail technically lost, it was more than made up for with the clarity of the image without glares. Obviously, the effect was most noticeable on windows, rivers, etc... but in certain circumstances try using this for portraits and you'll notice some of the specular highlights dissolve to create a more even result! This was something I accidentally discovered, but later found out is a fairly common use. I 100% would recommend having this as a new photographer or even maybe as an older photographer. If you're just a hobbyist photographer, this will help out and it will not break the bank. You won't notice any difference between this and a $400 CPL until you start getting technical with how you want to push your composition. At that point, you can look into higher "quality" glass, but in general, I see no problem with this filter for general use and always carry one in my filter case either as a backup or to use in dusty weather, rain, etc to keep from harming my nicer filters.
