I was completely satisfied.Darken the scene 10 light levels so you can take long exposures in daylight in total comfort. It is made of glass and looks good quality. I used.Comes with a leather case, lined with a soft fabric inside; velvet type which comes very well so you can wear it without fear of scratches.

These are great filters and holder. Works with a large variety of lenses, I use this frequently, it never leaves my camera bag.

After many reviews that I looked at on Youtube, I decided on the new K&F filter holder and have not regretted it so far. It is easy to use and makes a very high-quality impression. The use of the CPL filter is a great solution. Lever up, put it in and lever down again, done. Adjusting the wheel is also buttery smooth. In contrast to the first K&F filter holder, the filters, which now have a frame, can now be pushed in very easily. Not too easy and not too heavy either. A clear buy recommendation.

I can't say that I've mastered using the filters, but I feel like the build quality is top-notch and I'm looking forward to getting better with my photography.

This square filter system is much better quality than the cheaper equivalents. Since the filters have frames, those are easy to handle, without smudges and scratches. The size is enormous (good for wide-angle) and the CPOL integration is definitely an advantage.

I suggest to try out the entire setup at home before using it for the first time (the attaching mechanism of the filter holder to the lens ring is tricky, make sure it locks properly, else you might need to fish for it in the lake...)

SKU.1878 is a very versatile system and a quality product. The tab filters slide in and out of the holder with ease. So far no light has leaked out. I love that frame for my additional 100 x 100 and 150 x 100 filters get. It keeps fingerprints off the filter.

The company is located in Hong Kong. I would have liked to get extra adapter rings, but K&F Concept doesn't sell them separately, or so it seems. I contacted them through their website/email address and keep getting ads for their backpack. I was directed to get magnetic adapter rings, which are not for this system. It seems if you want to get adapters, you have to buy the filter holder and adapter rings.

This is definitely a product to buy. I look forward to taking pictures with it. It would be nice to have a wide angle sunshade.

I bought this because the kit provides me with the variety of filter mounts I need to cover my lenses. I have not seen any problem with unevenness or color streaks in my images. Focusing is a challenge, of course, due to the filter density. The mounting rings attach securely to my lenses and the connection between the rings and the filter holder is solid. My filter fits firmly in the holder. I suggest inserting the filter into the holder "off camera." Screw the appropriate mounting ring onto your lens, and then "click" the filter/filter holder combination into place. While still holding the camera in one hand and the filter holder in the other, try to wiggle it or pull it off to test that it is firmly attached and that it won't fall off while you are shooting.

excellent filter system. Very easy to use. Ordering from k&F Concept is easy. Highly recommended.

To be honest I was really hesitant to purchase this, however the price intrigued me enough to give it a try. I have to say this ND Filter is right up there with the best. It comes nicely presented and the case to store it in is great. There have NOT been any weird coloration in. The glass is high quality and easy to clean. Honestly I love this ND Filter.
