In the past I've taken nature shots in bright sunlight mostly with fairly cheap filters. This often spoiled the fun of taking nature photos in these situations, as the photos often had a color cast, blurring, etc. Accordingly, I was undecided whether I should try the filter from K&F Concept at all, but then I gave it a chance and that was good! As soon as you unpack it, you realize that you are holding an absolute high-end product in your hands. The protective case made of real leather, the brass-metal frame, the filter itself make an extremely (!) high-quality impression. Thanks to the brass frame, the filter can also be screwed onto the lenses extremely easily. The filter reduces light by 10 f-stops, so it's specifically designed for wildlife photographers who want to shoot landscapes in bright light without blown out or "flooded" areas. This also works great, without color casts, color fringes or other impairments. You don't "see" the picture that a filter was used and that's the main thing. I've never been lucky with cheaper filters in the past. The filter is super easy to screw on and off and doesn't affect the autofocus on my Canon R5 either. At least not when there is enough light, of course. I'm really excited and can say that with this filter, K&F Concept have completely eliminated my aversion to filters of any kind. Therefore 5 stars

purchased the K&F Concept Nano-X PRO Series ND1000 77mm filter for my photography gear and I am delighted with the quality and performance of the filter. The frame of the filter is made of high quality brass material and features CNC pattern design, which greatly improves the hardness and flexibility. Installation was also very smooth and durable. The ND1000 filter reduces light by 10 f-stops, allowing longer exposure times without color cast or loss of image quality. The K&F Concept coating technology also gives the filter a very low reflectivity of 0.15%, which increases light transmission and reduces stray light and ghost images. The filter also features 36-layer double-sided nano-coating, which is waterproof, dirt-proof and scratch-resistant, which improves the durability of the filter. The frame is also very thin and conforms well to the lens without causing dark corners when fitted to wide-angle and telephoto lenses. In addition, the filter comes with a high-quality leather storage bag that is purely handmade and specially produced for K&F Concept photographers. K&F Concept's flagship filter meets the highest internal standards and offers excellent optical performance. The classic high-end design and exquisite workmanship make it a valuable addition to any photography equipment. Overall, I would rate the K&F Concept Nano-X PRO Series ND1000 filter five out of five stars. It is of excellent quality and performance and offers excellent value for money.

The fit and finish are very good, the finish is super high quality, the packaging blew me away on all the positives as soon as I shot with it. Once I've shot with it I'll report back and see what the results are when shooting with the product. It's a bit on the high end of the stops for ND filters.

The filter is great quality and the price was perfect

i love this thing For a while my wife has been claiming that her late model iPhone renders my camera obsolete for all its camera magic tricks that can make any photo pop, but it's things like this that prove her wrong. We have just spent a week on Koh Samui visiting waterfalls in bright sunlight and the results I got with this 10 stop ND filter were amazing. My long exposure blows all of her shots out of the water. The filter is beautifully presented and feels premium. I didn't notice any distortion or odd color casts. This is just a great filter.

I've become a fan of K&F Concept filters. The glass is immaculate and the build quality of this filter is top notch. I attached before and after shots with the filter. As you can see, it's a strong ND that's great for specialty shots. It also comes with a really nice sleeve, and the box converts into a picture frame.

A+ lens, this lens is high quality and I love it. This is not my first K&F and I know for sure that my pictures will be great. The case looks good and came with a cleaning cloth.

ND filters darken light without changing color. This filter darkens the light by 10 f-stops (which is most effective for long daylight exposures). The filter is heavy and extremely well made. It goes perfectly with my Nikon prime lenses. This filter is of very high quality and produces excellent quality images.

This filter is top notch and is another example of how K&F creates outstanding filters for photographers around the world. This is my fifth filter from K&F and everyone has impressed me and this filter is no different. It delivers stunning results on a bright day. I tested it over about thirty different photos to see where the sweet spot is. If you are looking for a 10 stop ND filter then this is probably what you want and it comes with a really nice leather filter case.

The quality of KnF was really top notch. This is a beautifully optically clear 10-speed solid neutral density filter. As far as I know, it's as dark as it gets, and it's perfect for long exposures during the day to capture lightning strikes, or for taking beautiful cityscapes in the evening. This thing is optically perfect like any of the expensive German filters I own. The coating keeps moisture from falling onto the front when you're shooting in the rain and they're supposedly scratch-resistant, but I'm hoping to never try that. I now own several filters from this company and have been extremely satisfied with all of them. The build quality is as good as my German ones and you can tell how well they are made by the eaves where the filters are threaded onto the lens. Absolutely beautiful. And they also come with high quality cases. The only thing this company could do better would be to go back in time to when I was spending $300 a filter back then and offer their wares.
