K&F CONCEPT 49MM Polarising Filter Circular Polarizing CPL, Ultra Slim, Japan Optics, Multi Coated, with Cleaning Cloth (Nano-K Series)

I bought a set of these in different sizes to suit three lenses. Fair value for simple lens protection and image adjustment. Easy to fit and adjust.

Very good quality filter. Rotates very smoothly. I have several filters from K&F and all are excellent quality and very good value for money. I definitely recommend.

Does what it says really, much improves photos especially with car photography to stop reflections. Nice and thin too, definitely worth the price though higher end lenses might notice a little drop in quality, haven’t noticed anything on my kit lens. Only “issue” is I don’t like the blue tint on the filter itself, doesn’t affect photos but I think it looks a bit cheapy on the camera, a bit toy like. But doesn’t matter, doesn’t affect anything

This was bought for my Panasonic DC-FZ82D camera. It fits nicely and works well insofar as it reduces reflections. However, it also significantly reduces the transmission of light through the lens. This is a problem when trying to photograph pictures and items in galleries and museums which are behind reflective glass; there is little enough light in those situations. It's a long time since I last used a polarising filter and I don't recall the loss of light being so great in the past. Maybe a more expensive filter would allow more light through while still effectively blocking reflections?

Nice and cheap cpl filter, didn’t expect such nice quality from such cheap product, metal rim, clean glass

Ordered a cheapish filter to begin with to see if suited me. At first fit it appeared not to vary polarising effect as I rotated it on the camera. But upon further trials on the reflections off my car bonnet, it does vary with rotation as described. Just got to get the angle right. Quality is very good for a budget filter, but one thing I don't like is how hard it can be to remove from lens. Iy takes a few rotations on sliding ring before it seems to pick up on the threads and starts to unscrew. Not a massive issue, but would be a right pain if needing to remove in a hurry.

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!

Great value budget filter from K&F that works really well. Easy adjustment of light via well made rotating alloy chassis.

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.

Need I say more?

Très bon rapport qualité prix

+ Bra budgetkvalitet! + Bra polarisering! -Sätter sig fast lite i gängan men man behöver ju inte dra åt det med skiftnyckel när man ska ha på det. Jättebra produkt🙂👍
