System with an excellent price/performance ratio. The filter holder system makes it easy to frame before installing the ND 1000 filter.

Of course, in preparation for our round trip, we also needed a good filter system. We spent months reading, getting information, watching and comparing videos. In the end we decided on this system. And that was a great decision! There are definitely better systems out there, but also for a lot more money. Everyone has to decide for themselves whether a hobby photographer really needs it. With this system, we are talking about real glass - not plastic! The glass is not colored but coated, so there are no distortions or blurring at the edges. The only drawback is that the glasses are quite difficult to slide into the holder - BUT nothing slips out and nothing slips. Perfect for quick position changes. We got used to it quickly. The results with the filter are as desired, there is nothing to complain about. We are thrilled and would choose this filter system again and again. We bought the kit with the holder including all adapter rings, the graduated filters, the 64 and the 1000 - everything was great! Have fun capturing memories!

Very good Fitleo ND and filter holder system, I use it with a Tokina of 12-28h, the results are quite good

I received the new X-PRO filter set today and have already tested its applicability in the apartment. A judgment on the quality of the filter glasses and the combinability in a shot I still deliver ... The supplied box holds the holder + adapter rings + CPL + ND 8/64/1000. At the drawstring you can pull out the compartments and then very conveniently remove the filters. The plastic filter frames are decently sharp-edged, but not unpleasantly so, and allow you to remove and handle the filter without having to touch the glass. The tabs on the frame also make it very convenient to pull the filters back out of the holder, especially in any order. I have ordered two empty frames in 100 X 150 on the manufacturer's site, which should take my graduated filters after receipt, which I have from another manufacturer. I am curious how well this will work. If it works out, I'll have a complete system for myself, with CPL, three ND filters and two graduated filters (Soft 0.9 and Reverse Soft 0.9). Sliding the filters in and out of the holder requires some force, but is neither awkward nor imprecise. This will then also allow the graduated filter to be aligned well. The handling of the CPL filter with the insertion bracket is great, the turning mechanism is a bit rough, but precise. Screwing the adapter rings onto the lens goes very well, the threads are cleanly made, nothing rubs. Attaching the holder to the adapter ring is also a pleasure and the existing locking screw is very welcome, as the holder can be rotated relatively easily on the ring. The handling of the system has already convinced me, with "only" two slots I can live well for my needs and I look forward to the first use, in the next few days, in the great outdoors and with cold fingers. I have so far worked with round screw filters and waived graduated filters, which I now want to change. I also looked at the system from Rollei (Mark II), which can not keep up with the X-PRO from K+F in handling. Everything very flat and fiddly, offers little surface for holding and joining the parts. Getting the polarizing filter or adapter ring out of the holder again is no fun and almost impossible with cold fingers. K&F has solved this much better. Who wants to use graduated filters is very well served with the X-PRO set, who only needs gray filters, I would advise a magnetic round filter set, whose diameter is well above its largest lens, which is even faster to use, is more compact and should then not darken with several filters in parallel.

This is a very versatile system and a quality product. The tabbed filters slide in and out of the holder without difficulty. So far, no light leaks. I love the ability to get frames for my additional filters, 100X100 and 150X100. It keeps fingerprints off the filter.

The company is based out of Hong Kong. I would have liked to get additional adapter rings, but the company does not sell them separately, or so it seems. I've contacted them via their web site/email address and keep getting ads for their backpack. I was referred to get magnetic adapter rings which are not for this system. It appears if you want to get adapters you need to buy the filter holder and adapter rings.

This is definitely a product to purchase. I look forward to shooting pictures with it. It would be nice to have a wide angle lens shade, but then, you can't always get what you want.

am a passionate landscape photographer as a hobby and have now switched from the screw filters to this rectangular filter system from K&F. The screw filters were all fine, but you don't have the option of attaching a graduated filter to the ND filter in order to achieve even nicer effects. It is mounted on the lens using so-called adapter rings, which are included in the most common sizes for lenses. After attaching the adapter ring to the lens, the filter holder is attached. This is secured by a small lever (spring-loaded) and later released again with this. Now you can slide the filter plates into the filter holder. This lifts a bit severely but it should also hold and must not wobble. It is also important to observe that the filter used is close to the lens so that no more light can penetrate between the filter and the lens, which could possibly ruin the recordings. In terms of quality, the system makes a good impression considering the price. The only thing I noticed negatively is that the filter holder has some play after it is placed on the adapter ring and why there is no adapter ring for a 55mm filter diameter in the set, I also ask. 55mm is a common diameter for lenses. I can highly recommend the K&F system for amateur photographers. The professionals will probably use filter holder systems from other manufacturers, but they also cost a lot more.

K&F Concept Square System Filters Kit 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.
