Nothing short of delivering its single purpose in life.

Well maid and makes handling the filters easier

Visually, the filter set is of very high quality. The optical quality will have to prove itself, but I don't have the slightest doubt about this.
The only point of criticism is that the very nicely executed leather storage box/pouch is very large in size, which makes transport in a backpack almost impossible. It would be better to provide the filters individually with a protective pouch. Transport would be easier and more customizable.

I bought the rectangular filter set directly from K&F. Since I have worked with screw filters in the past and had the problem with vignetting when screwing several filters on top of each other, I have 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, as a hobby photographer I was looking for a cheaper alternative. When I saw several reviews on YouTube, I decided on the K&F set, which is half the price of Haida and CO. I have absolutely no regrets about my decision. The filter holder is very valuable and well thought out. I particularly like how the polarizing filter is attached to the holder and how it can be adjusted using the small wheel. The filters themselves are made of optical glass and show no color cast and are also well coated. Another positive aspect is that the filters have a plastic frame with a tab. This allows the filters to be inserted and removed without annoying fingerprints. A bag is included to store and transport the holder and the filters in it. Also included are various adapter rings for different filter thread diameters. As a landscape hobby photographer, I no longer want to do without the advantages over screw-on filters. I give a clear purchase recommendation for amateur photographers and professionals too! I wasn't expecting such excellent quality for this price. It's amazing what K&F delivers here.

Great value for money!

I recently purchased this set of filters for my Nikon camera but they also fit other brand cameras I own. That is a huge plus for me. For the money, this filter set perfectly meets my needs. This set is good quality, comes well packaged and arrived in perfect condition. I would recommend this set to others.

The filter does what it is supposed to do, it extends the exposure time. I haven't noticed any vignetting or wrong color reproduction so far. And so I'm satisfied. The packaging of the filters is very good and practical, some higher-priced filters can't do that so well.

I am an amateur and gathering my gear little by little. I bought several K&F items and I have to tell, these guys put love on what they do. Any detail es great, the metal parts are fine, the mobile parts works perfect. A great maker!

The picture quality on these filters is by far ahead of variable ND filters. I am a videographer and rely heavily on ND’s to get the shots I want.
They are super Sturdy and the I love the case the filter came in. Not to mention having this on your rig looks really cool!

Great value. Filters fit snug and don’t let any light around them. Filters come in a quality case.

Todo en es perfecto
