Each filter come in individual plastic holder with cap, make it easy to install the filter on my camera without adding fingerprint on the glass. I can choose to use the cap that come with it or the original fujifilm cap. Especially the slim profile filter ring make it easier to use with oem cap. The uv filter have good transparency while the cpl work as expected. Highly recommend this 49mm filter set for X100 user.

I was very surprised with this filter kit. The glass seems to be great quality, they both came in their own lens cases and lanyard strap, and a couple of bonus cleaning cloths. As far as the results, absolutely brilliant! I was a little skeptical to be honest since I had a cheaper polarizing lens and it just made the pictures blurry since it was inferior glass. This filter not only got rid of my reflections in the car and made the photos perfect, but the pictures were as clear as if I didn't have a filter on. I literally could see my entire body and camera in the reflection of the car and I put this filter on, turned it a little to adjust and voila, I disappeared like magic. This is better than editing in Photoshop, in my opinion, so this is a real world scenario filter I will definitely be using a lot.
As far as the clear UV filter, I'm not sure how much i'll be using that since I cap my lens often and don't shoot in dusty places but....if i run into a scenario like that, I wouldn't hesitate to. Both filters have great glass and don't seem to introduce any warping or distortion in my pictures. I've invested a lot of money in my L lenses and want to protect them as much as possible so getting a high quality filter is important or else there is no point in having good glass in your lens. I think this filter kit is a good compromise since I get protection and don't see any degrading effects. Keep in mind, they are not labeled but i didn't warrant that to lose a star. A sharpie or a piece of masking tape on the case can fix that. If you are looking for a polarizing filter, this one is giving me amazing results and has made taking pictures a lot more fun! I didn't know i needed it until I had one.

these cause zero degradation in photo quality, and provide significant peace of mind knowing that i can clean the filter and protect my $1,000 lens from scratches, etc.

The product arrives. us with a well-finished packaging as classic of the k&F brand

In the package we find
- cpl filter
- uv filter
- 3x cleaning cloth
- lens cap
- 2x wrist strap

I will not dwell on the technical specifications since they are already widely mentioned in the product description but, I will tell you about my experience of use and impressions.
As soon as we open the package we immediately notice how each filter has its own case and are accompanied by a cleaning cloth, an apollo strap and a lens cap.
The filters appear to have an excellent quality in relation to the selling price, the surface finish avoids flare and greatly reduces the degradation of the image, the uv filter is almost imperceptible when analyzing the raw file while the cpl tends to be minimally visible as regards the degradation but it is all solvable in post production.
The filters can be used in pairs one above the other thus adding the effects we want to have.

in conclusion it is an excellent kit, not professional level but certainly much superior to the entry level range, my final rating is 5 stars

I am an amateur photographer
The glasses are perfect
No defects
Very good quality
Maybe the packaging could be improved if there was a criticism

K&F Concept 77MM UV Filter & CPL Polarising Filter HD Anti-Reflection 28 Layer Multi-Coated Slim MRC Optical Filter (Nano-X Series)

This is an impressive two-filter kit. Common to both filters, they:
- Offer excellent transparency
- No discernible anomalies in the glass
- Excellent image quality
- No coloration
- The low reflectivity coatings offer easy cleaning and scratch resistance
- The ring and threads are well formed
- Sufficiently thin form-factor, excellent for most applications including UWA
- Nice anodized finish
- Satisfactory knurling to aid installation and removal
- Hard cases
- Lens caps, lanyards and microfiber cloths add value

Additionally, the polarizing filter rotates well and polarizes effectively. Excellent.

Misses?
- There are no labels on the filter cases. I'll make my own labels as I don't like to carry boxes.
- The filter cases are a bit thick as they are designed to hold both a filter and a mounted lens cap.

Nothing major but worth noting.

The K&F products I have had over the years are generally well designed with excellent attention paid to detail. This two-filter kit is no exception. Worth considering. Recommended accordingly.

My personal impression is that K&F has slowly become the market leader. I have complete confidence that I will get good quality here. The workmanship is flawless. (I'm only an amateur photographer though and can't give you any comparison values ​​for other filters.)

I actually only see potential for improvement in the packaging. The plastic boxes for the filters are unnecessarily large and always unlabeled, so that with a whole collection you have to get to it yourself if you want to know what's in it. It can be done better.

Being a professional photographer requires me to always improve the quality of the pictures and this UV filter is excellent not only to protect my lens but also is good at reducing reflections and glare allowing to and has the colors in the pictures.
For example, when it's too much sun it is very difficult to take interesting photos, however with this filter the sky in the picture looks nicer it allows for me to get amazing landscape photography.
This filter also is good to protect my lens from scratches and dust which is very useful considering that I am taking pictures mostly outside.
The actual filter is very easy to install and remove, requiring just to screw it on the lens and it stays securely in place and because the lenses are very light, it does not add any extra weight to the camera.
This is a good and efficient way to improve my photography even when I'm outside and it is sunny.
