These filters are great. I have zero issues or complaints. They go on nice, and come off as easily. They do a great job too. They're really good for the price, which I am super impressed with. They're super reasonable compared to name brands, and just as good in most cases. I confidently recommend K&F =, not just for these lens filters, but nearly any third party camera accessory. They just keep impressing me.

This kit bundles three essential filters—the UV protector, circular polarizer (CPL), and a variable neutral density (ND2-400) filter—designed for 67mm lenses in the Nano-K (or equivalent) line of K&F CONCEPT. It’s aimed at photographers wanting to cover protection, polarized scenes, and light control without assembling separate pieces.

✅ Pros

High optical quality & excellent coatings: Reviewers highlight the smooth build, strong glass, and no noticeable colour cast or “X-pattern” when using the ND component.

Versatile kit: From everyday protection (UV) and reducing reflections (CPL) to long-exposure or bright shoots (variable ND), this gives wide coverage.

Good value for money: Compared to buying separately, the bundle offers strong performance at a more accessible price point.

❌ Cons

Variable ND curve limitations: As with many adjustable ND filters, at the darkest settings you may still see vignetting, or slight exposure shifts especially on wide lenses.

Single size (67 mm): You’ll need step-up or step-down rings if your other lenses use different thread sizes.

Kit complexity for beginners: Having several filters is great, but figuring out when and how to use them (especially the variable ND) still requires some experience.

As a photography beginner - (enthusiastic,but a lot to learn), I found this filter set to be a great value for the price, offering quality performance without costing too much. Though the lack of definitive stops makes precise adjustments a bit challenging for someone like me, the filters maintain colour accuracy and clarity in my photos. Overall I think that this kit is an excellent choice for beginners looking to experiment with filter effects, but who are on a budget.

I like K&F concept filters. I use a circular polarizer or a VND on almost every type of shoot personal and professional. Most most of my lenses are 67mm and I have no issue with vignetting, or color casting. The filters a fantastic quality. The filters work great. The case is great lots of storage room for extra filters and step up rings. The quality is nice hard shell and good zipper. Overall the kits a wonderful value.

Key Features:
- Affordable, all-in-one kit with UV, CPL, and ND2-400 filters for lens protection, glare reduction, and light control.
- High-quality optical glass with 18-layer coatings minimizes reflections (~0.2%) and resists dust/water/scratches.
- CNC aluminum frame ensures easy handling; slim design reduces vignetting.
- Includes static-free microfiber cloth and hard-shell pouch for convenient transport and protection.
- Universal 82mm compatibility suits most pro lenses; ideal for beginners and hobbyists.

Things to consider:
- Variable ND may show X-patterns or color casts at higher stops (>5-7), especially on wide-angle lenses.
- Minor sharpness loss and ghosting when stacking filters or using fast primes.
- ND limited to 9 stops, insufficient for extreme long exposures.
- Fiddly ND adjustments; no click stops or magnetic options.
- Budget-tier optics may not satisfy pros needing flawless performance.

Great value and functionality for beginners/intermediates, who enjoy shooting landscapes or video. However, this product can vary with pros, who may want more premium filters for critical work.

I’m really happy with this K&F Concept lens set so far. Each filter fits my Canon 58mm lens perfectly and threads on smoothly without feeling loose or wobbly. The glass quality looks very clear, and I haven’t noticed any unwanted color tinting, distortion or vignetting in my shots so far. My camera has not any issues with focusing either. The UV filter has been great just using it for everyday protection. I feel the CPL helps cut down the glare and deepen the skies nicely, and the ND2-400 gives me a ton of flexibility when shooting outdoors and if I’m working with slower shutter speeds. It’s a solid setup that helps give your shots a step above the rest. The case provided that houses the lenses is very well built and does an awesome job at keeping things scratch-free & organized. For the price, you’re getting a really outstanding well built filter set that any camera owner would be proud to have. Plus it’s a well-made set of filters that perform far better than I expected. I have so many different lenses but this kit contains a great variety and an all in one setup- that’s value for your money right there.

These filters are top notch for the price. I lost my last ND filter and needed something quick for next day delivery for the last few days of my trip. The nd filter selection was sturdy but yet easy to change and didn’t have much vinetting at all like others in the same price range. Didn’t realize the case came with it and it’s sturdy and actually stores 2 other filters and still functions and protects like it was designed for. The other filters are clear and offer great color accuracy!

When it comes to camera gear, often I find the prices are skies the limit. You can buy crazy expensive filters, lenses and even bags to kit yourself out. I debated very heavily about whether I had the skill and need for an ND filter, and how much I needed to spend to get the effect.

As stated, I'm a photography novice. Lots of people say not to go budget for glass. That said, K&F Concept makes some great camera gear for a good price. I purchased filters that fit all but my telephoto lens along with some step down converters. I am fairly pleased with the result of these filters. The kit came with a nice carrying case (that will fit more filters than the product came with) and some cleaning clothes. I had no issues threading it into my lens.

Although I wish it had more definitive stops, it has been fairly good in my experiments. If you go too far, you get a dark X. Because there are no "clicks" or feedback at each stop, you have to use your eyes to set a stop which means removing the camera from your face. It would be great to keep my eye in the viewfinder and actually see what each stop does without having to divert my gaze to the lens. But otherwise, the photos seem to maintain their color accuracy and there are no uneven spots (to my eye) in the clarity of the photos taken with this filter. Again, it would be easier to use if it had stops at each point in the ND filter.

I haven't used the UV filter, and don't really expect to, but the CPL filter will get some use. Overall, I think this is a great starter set of filters for a price that allows an easy path to experimentation. K&F makes really great gear that functions well, so I feel good about this purchase. Sometimes the cost of camera gear prohibits people from even considering something other than their phones.

It was absolutely horrendous quality. Nearly ruined my entire trip, thankfully my friend had a better one by HOYA. PLEASE think twice before buying this. I used it on my Panasonic Lumix FZ1000M2, and it kept blurring my photos.

Edit: Soon after I posted this review, the customer service team reached out to me, and they were really nice about helping me find a better product within K&F. Although I stick by my word, this particular filter was not too good on my camera, but the company is super good and it's customer service team is amazing. I recommend checking out their slightly more expensive but better quality equipment.

High quality lens set that consists of 3lens.
Nd2-400 filter lens....this will reduce the brightness and adjustable.
Cpl filter lens....this stops and reduces glaring while enhancing the colors, helps enhance to give a more natural color.
Mcuv filter lens.......protects lens and blocks ultra violet light.
A lovely case was included with this set, case is a strong hard shell with soft fabric over it, inside had sewn in fabric slots to keep the lens protected and each lens came in their own soft plastic case. Case is really nice and protective and durable.
I use the uv filter for a lens protector and to stop the ultra violet light. The nd2-400 filter is great for very bright days and need lower light setting.
All 3 lens are exceptional whether you're taking photos or recording a video, they look professional and are awesome additions for photography. The really add to photo and video quality and function flawlessly.
They fit perfectly on my Canon
EOS M6 Mark 2 ,I'm very happy with this lens set.
