the quality of these filters seems to be on par with others (more expensive ones). The course is clean and evenly straight. The very well thought-out pockets, with their pull-out tab, offer fingerprint-free handling. Clear purchase recommendation on my part...!!!

This is great if used in the right situations. I like to use it on my Fujifilm cameras. Build quality is as expected which is pretty decent. I have no complaints. If you don't like this one, you should try a "Glimmer Glass" filter.

A mild light reducer. Can be easily plugged in together with other medium-strength ND filters. Quality like other manufacturers offer. Good optical glass.

bought the filter bag to have all the filters at hand more quickly and not to have to search for them, and to save space. The bag is of high quality and fits perfectly for 100x100mm filters. A total of three (theoretically four) different filters can be stowed in it. So it is perfect for a standard ND filter set (8,64,1000). The inside of the bag is completely lined with microfiber so that the filters can be transported in it without additional protection. As a smart feature, it has a pull-out mechanism. This means that if you open the bag and pull the tab, all the filters are offset and highlighted so that you can grab them much better and read the name directly. I bought another glass filter at the same time - ND64. Since I already own an ND8 from another brand and the ND1000 from K&F, this was of course still missing in the series. Overall, I am super satisfied with the quality of K&F. The filters (update 2020) have almost no color cast anymore. In certain light situations, my ND64 filter turns green. However, this can be corrected without major problems during image processing. The shape of the filter (no round filter) also means that there are no problems with vignetting or falling sharpness. The images are therefore almost unaffected in terms of image quality. The processing is top (no sharp edges, stains, etc.) and the price speaks for itself. All in all, I'm very happy with the entire filter system from K&F and will probably get hold of the gradient filters soon!

the quality and package of this set are satisfied, a small pouch to fit the ND filter glass.
By the test, I see there is a little color casting and darkness of this filter but not an issue in comparison to other filters I've used. I could edit it easily in post process.

This is straight out of the camera and hasn't been retouched. Quality is good, the stones are sharp the water is soft, all in all not a bad product.

Easy to use great photos just what I wanted.

Bought this to replace the cheap graduated filter set which provided terrible pictures. First thought as soon as you open the boxes is how well everything is presented and the build quality. All metal parts precisionally made. The graduated glass is of high quality. The pouch looks like leather and has an easy pull tab to gain access to the filter. The filter folder can rotate on the adapter. This is sprung loaded and is easy to attache and remove on the adapter. Anyone looking for good quality and value should consider this kit.

An amazing bit of kit for any photographer. So much fun to be had with the accessories within this bundle and it’s made my photos even better. Sure there’s probably more expensive options out there but I’ve been very impressed with these and would recommend to anyone.

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.
