It comes in a sturdy plastic case that's ideal for storing the filter and protecting it from scratches in case you need to store it in a camera bag with other items. The filter itself has a solid construction with clean and clear glass so there are no marks to be seen. The 72mm thread fits perfectly on my Sony A-mount kit lens, and I also found the included lens cap particularly helpful (my lens didn't have one previously). After testing my camera with and without the filter, I noticed the difference immediately — the filter significantly reduced the amount of "haze" I could see when pointing the camera at a particularly brightly lit area (that was natural light coming through a window). Also included in the kit is a cleaning cloth and a lanyard that keeps the cap attached to the lens, which come in handy should you need them. In summary, a good value item.

Review for: “K&F Concept 72MM UV Filter — HD Ultraviolet Filter Scratch Resistant Lens Protector Filters with Lens Cap Cleaning Cloth for DSLR Cameras (Nano-X Series)” Brand: K&F Concept Size: 72MM The K&F Concept 72mm UV filter came in a plastic container inside a plastic-wrapped box, with a 72mm lens cap, wrist strap, and microfiber cleaning cloth. I checked on the K&F Concept Canada website and the price on the list (currently $36.99) is the same, although their website says a special price of $46.06. I always put a UV filter on the front of my lens to protect it in case it gets dropped. K&F Concept is a good name when it comes to filters, so I expect it will be decent glass as well. I'm impressed that it came with a lens cap as I lost mine. The plastic case with the wrist strap is great for keeping the filter safe when not in use.

The filter comes in a plastic carrying casing with high quality foam to protect it. The filter is a tight fit in the case so you can be sure once stored it wont move around or get damaged during transit.

The filter itself feels to be of good built quality with metal frame holding the glass in place. I like the lever to adjust the stops, the action is smooth and will not move on its own. I would have preferred if K&F included a lens cap just in case, I wanted to leave the filter on the camera.

Considering the price, the image quality is comparable to high end products. I found the image quality to be excellent as I did not notice any chromatic aberration, loss of definition or the dreaded X from graduated filter.
You can see some product and some test images I did at home to test the product. I hope you found this useful, if so, please vote positive below

My first experience with the K&F Concept filters was with the purchase of a light pollution filter I've been happy with, particularly liking the grippy knurl added to the edges of the filter. After accidentally scratching my Hoya NXT Pls CPL 82mm filter which is more than double the cost of the K&F filter, I decided to purchase the K&F Nano Series CPL filter and see how I like it. Moreover, I also chose to go ahead and buy a 95mm version as well, to replace a Pro Optics (Adorama house brand) filter that I thought might be a lesser quality filter. Both K&F filters arrived today and a visual inspection of them reflects a quality product as I expected. However, one minor complaint is that I like the round K&F filter case which as a rigid plastic insert that appears to be grooved to support holding any of various sizes of filters securely in place in the case....that is, perhaps for a range of filter sizes, K&F may be using the same case to save manufacturing costs. However, while the 82mm filter arrived with that same case, the 95mm filter was in a more common, square plastic case with foam cutout to hold the filter. Still fully functional, just not as nice as the case provided for the 82mm filter. I don't expect to see any problems with the cheaper case, but it is the type that frequent use could find the plastic hinge wearing out eventually; I simply favor the 2-piece round case of the smaller filter.

This product came in a very luxury box. It's nice to touch and open. Filter is in the plastic case that is good, if you want to take it and you need to be sure what everything will be fine. It changes very smoth and comfortable, quality is perfect. There are scars on the ring with which it is very convenient to change the absorption level. I bought a 77mm for samyang, but i definitely think to buy 82mm for my EF 24-70.

The first impression was positive, the packaging and plastic case protected the filter when transported to me.
The plastic case makes a stable impression and has a simple yet stable closure, so that you can store it loosely in the camera backpack.

The setup help is marked (non-linear) and has two end stops. The first attempts with the ND filter were quite okay, in better weather I try the next river or in the city and I will submit the results if necessary.

The package containing the K&F Concept Nano X-Series Variable ND Filter ND3-ND1000 Gray Filter 67mm (1.5-10 stops) was delivered quickly and safely packed.
I love taking pictures and was happy to be able to test this filter.
The black outer box with the filter was once again covered with a plastic film, so that also no moisture could penetrate. The filter itself is in a high-quality plastic case. The flap of the case is magnetic. So no unnecessary fumbling around to get to the filter. Very practical: The filter can be easily lifted out by a strap.

The filter itself is made of Japanese optical glass with 28-layer nano-coating on both sides, which should prevent some lens reflection and of course glare from div. light sources. According to the manufacturer, the ND filter is waterproof, oilproof and dustproof, which is good for the requirements especially in nature and hiking. I have the feeling that the filter is very robust. But also has quite a weight with lens size 67 mm. Of course, the price is also accordingly appropriate.
The frame of the filter is made of aircraft aluminum, has an ultra-wide angle construction and is just 7.4 mm thick. Those who, like me, have always used a few different dark gray filters will appreciate this fact, especially when hiking. You simply need less space in your backpack and the weight is also kept within limits. One case, one filter.
I use gray filters especially when taking pictures of water at the lake or of flowing water or waterfalls. Also, for long exposure shots of places you'd like to photograph without people, a piece like this is fantastic.
The function of this adjustable filter is quite simple. Just press the handy slider and the filter will darken or lighten as needed. So you can easily try different settings and effects without having to constantly change filters.
Conclusion: the price is in the normal range with this kind of aperture level adjustability. Sure there are cheaper ones, but the K&F filter is already built a bit higher quality. The results are quite respectable. Since I'm not a professional, but just enjoy taking photos, this filter is actually a great companion for me and I'm happy to recommend it.
See photos, which I will post a little later due to the (somewhat stressful) Christmas season ;-))
