100x150mm Filter Protection Holder 2 Pack - Nano X Pro Series

Incredible quality frame!

They perfecty fit my square filters!

Just what I expected, works great. perfect fit for the 100x100 filter.

Great way to add protection and use the filter system with filters that didn't have the holder

Finally found an ND filter which can be installed inside the Smallrig lightweight matte box 2660.
I did have to remove the holder frame to make it fit. This can be done by carefully pulling appart the frame sides with the lips. In doing so you can op out the filter while keeping the frame intact.
Filter quality seems to be ok and it comes with a very well designed holder with an extraction ribbon which avoids having to touch the surface of the filter when taking it out.

I bought the rectangular filter set directly from K&F.
Since I have worked in the past with screw filters and when screwing several filters on top of each other got the problem with vignetting I wanted to buy a rectangular filter set for a long time.
Since the sets from NISI, Haida and other well-known manufacturers are very, very expensive, I was looking for a cheaper alternative as a hobby photographer.
When I saw several reviews on YouTube, I decided on the set from K&F which is half the price of Haida and CO.
I have not regretted my decision until now.

The filter holder is very high quality workmanship and well thought out.
I especially like how the polarizing filter is attached to the holder and how it can be adjusted via the small wheel.
The filters themselves are made of optical glass and show no color cast and are also well coated.
Also positive to highlight is that the filters are provided a plastic frame with a tab.
So the filters can be inserted and removed without annoying fingerprints.
Included is a bag to store and transport the holder and the filters in it.
Also included are several adapter rings for different filter thread diameters.
I as a landscape hobby photographer would not want to miss the advantages over screw filters.

From me there's a clear purchase recommendation for hobby photographers and professionals!!!
I would not have expected such excellent quality for this price.
Madness what K&F delivers here.

I bought this filter set for landscape photography.

Previously, I had been traveling with a screw set from another company. I was then able to screw this onto exactly 1 lens. (I got it to fit a 24-105).

Experience has shown that screw filters are simply only partially usable (in my opinion).
If you use an ND 8x filter, you can safely screw it on the lens and work with it. As soon as it gets higher, the camera is overstrained. Setting a focus manually, for example, is an impossibility with a permanently installed 1000x filter.

This set allows you to set up the camera in peace. Compose the image, set the focus. To adjust the polarizing filter. When everything is ready, you can add 64x or 1000x and take care of the exposure.

The whole set is incredibly easy to use. Each filter is in a frame, which in turn has special handles.

The set comes in a handy bag.

I don't really want to talk about the space requirements. More compact is the screw set in any case, but at this point handling is simply more important to me.
This set allows me to mount the filters without leaving greasy finger marks on the filter. That is worth more to me at this point.

What I particularly like about this concept is the fact that you can now buy graduated filters and the like afterwards and customize the set the way you like it.

The system with the CPL filter mounting beats everything I have used so far. The mounting of the holder is also easy by hand. The quality of the filters themselves leaves nothing to be desired. This makes filter photography simply fun!

I have been an avid photographer for over 40 years but have never really wanted to use filters before now, always preferring to keep my images as natural as possible, except for maybe the occasional minor tweak in post production. However, recently I decided to take the plunge and invest in some filters to help
achieving the correct effects with low shutter speeds and landscapes. I undertook a lot of research, including all the main brands Lee, Cokin and Nisi etc, especially as I needed a set that would accommodate a relatively wide angle lens too, so I was looking at the 100mm to 150mm sets. Eventually deciding I could just about manage with the 100mm set, as I didn't really want the expense or bulk of the 130mm/150mm sets. I discovered the K&F brand which I had not heard of before, and in what I read and watched I was very impressed. So I eventually decided upon this Pro 3 filter set, 10 stop ND, Grad ND and Circ Polariser. It was expensive, but good value when compared to competitors for a set of similar specification.
So what is the set like, well it is very impressive. It arrives well packaged in a very professional looking box, orange and black. Inside is the leather effect protective case, which contains the 3 filters, the ND & GND in frames (each individually wrapped too for extra protection in transit), the filter holder, the lens adapter rings, and a simple manual. The holder is aluminium and feels very strong, it has a very professional and functional design, and the subtle orange accents (to represent the K&F brand) on the both the CPL rotation wheel and the adapter ring locking nut are striking. The filter frames that encase the glass filters are very thin, but they feel solid enough. They are pre installed on the 2 square filters provided (ND/GND), but reading the instructions they do 'appear' to dismantle to enable use on other similar sized filters. I hope at some point K&F will sell individual frames, but neither the K&F site or Amazon appear to sell them at this time. This is still a very new product I believe, so hopefully they will be available in the not too distant future. I look forward to them being available as I expect, given the quality of this set, I will be expanding my collection of these filters at some point in time.
To use the filters, you simply attach the relevant adapter ring to your lens, then attach the filter holder, and then put the required filter(s) in. The CPL is locked securely in place from the top by an ingenious locking mechanism and it can be rotated when in place by the wheel at the side, which is really cool. The square/rectangular filters then just slide in front of it, in the 2 available slots as required. The filter frames have a very reassuring fit & hold when in place in the holder. They also have raised tabs at the top and bottom of the frames to help with vertical adjustments, and also help to keep the glass clean by keeping fingers away. So far I have only done some very basic test shots but the results have been excellent, so I am really looking forward to testing this set fully in the coming days/weeks, and hopefully producing some great results.
Overall, I have been really impressed by the quality of this product and of the K&F brand. So good was the workmanship I am just awaiting a new K&F tripod which I hope is just as impressive. The build quality of this Pro Filter set is excellent, great value for money and it certainly looks very professional, so I can say with confidence that I really look forward to using more products from K&F.

After many reviews I have watched on YouTube, I have decided for the new K&F filter holder and so far not regretted. It can be operated top and makes a very high-quality impression. The use of the CPL filter is great solved. Lever up, put in and lever down again, ready. The adjustment via the wheel is also smooth as butter. In contrast to the first K&F filter holder, the filters, which now have a frame, can now be inserted very well. Not too light and also not too heavy. A clear buy recommendation.
