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! ## Features - K&F CONCEPT circular polarising filter made of Japan optical glass, deepens the intensity of blue skies, reduces or eliminates glare. - Multi-coating reduces reflection, reduce glare and improve saturation. - Aluminum alloy frame, ultra slim rim profile to avoid vignetting on wide angle lenses. - CPL filters are good for skies, waters, foliage. They can dramatically enhance these natural elements, giving images better appearance. - Please verify your camera's lens thread size first (usually marked somewhere on the lens barrel or the lens cap). This number is always preceded by a "Ø" symbol. i.e. Ø39 = 39mm lens thread size. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0C2GMHWXZ | | Best Sellers Rank | 1 in Photography Polarizing Filters | | Brand | K&F CONCEPT | | Brand Name | K&F CONCEPT | | Coating Description | Nano Coating | | Coating description | Nano Coating | | Country of Origin | China | | Customer Reviews | 4.4 out of 5 stars 3,024 Reviews | | Enclosure Material | Optical Glass | | Item Dimensions L x W | 39L x 39W millimetres | | Item height | 0.1 centimetres | | Manufacturer | Shenzhen Zhuoer Photograph | | Material | Optical Glass | | Photo Filter Effect Type | Polarizer | | Photo Filter Size | 39 Millimeters | | Photo Filter Thread Size | 39 Millimetres | | Photo filter effect type | Polarizer | | Photo filter thread size | 39 Millimetres | | Product Warranty | 1 year warranty | | Water Resistance Level | Not Water Resistant | | Water resistance level | Not Water Resistant | ## Product Details - **Brand:** K&F CONCEPT - **Material:** Optical Glass - **Photo filter thread size:** 39 Millimetres - **Coating description:** Nano Coating - **Photo filter effect type:** Polarizer - **Water resistance level:** Not Water Resistant - **Product dimensions:** 39L x 39W millimetres - **Photo Filter Size:** 39 Millimeters ## Images ![39MM Polarising Filter Circular Polarizing CPL, Ultra Slim, Japan Optics, Multi Coated, with Cleaning Cloth (Nano-K Series) - Image 1](https://m.media-amazon.com/images/I/81QMMV7nzEL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Decent bit of kit *by A***S on 29 December 2025* Great addition to my kit for car photography ### ⭐⭐⭐⭐ Good filter, but potential issue at full zoom. *by M***S on 7 October 2025* Update: K&F have been in touch and sent me the X Series filter that does work fine at all focal lengths.

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 ## Frequently Bought Together - K&F Concept 39mm Circular Polarizer Filter Ultra-Slim 18 Multi-Coated Optical Glass Circular Polarizing Filter for Camera Lenses with Cleaning Cloth (K Series) - K&F Concept 39mm MCUV Lens Protection Filter 18 Multi-Coated Camera Lens UV Filter Ultra Slim with Cleaning Cloth (K-Series) - K&F Concept 39mm Variable ND Lens Filter ND2-ND400 (1-9 Stops) 18 Multi-Layer Coatings Adjustable Neutral Density Ultra Slim Lens Filter for Camera Lens (K-Series) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/542073106-39mm-polarising-filter-circular-polarizing-cpl-ultra-slim-japan-optics](https://www.desertcart.us/products/542073106-39mm-polarising-filter-circular-polarizing-cpl-ultra-slim-japan-optics) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-16*
