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.

switched to the Kentfaith filters because I was absolutely not satisfied with the image quality of the Haida and NiSi. Haida always had a magenta cast and NiSi always had a blue cast. As far as this is concerned, the Kentfaith square filters are simply impressive and convince with the best quality! I now own a few of these filters and I'm still a long way from the end of my collection of kentfaith filters. I can only recommend these filters to everyone, the workmanship is fantastic and the quality too. The filters arrive safely and very nicely packaged. Each filter is packed in a safe and good quality leather sleeve. If you value very good filters that are colorfast, you should choose the kentfaith filters. I hope this review could make your decision a little easier.

High-quality optical glass without color dominance.

Great quality from K&F. All K&F rectangular filters I have purchased are 100% quality and free from defects.

Simply great quality.

have had this a while now to go with the appropriate adapter kit and holder. This filter is seriously well made and I cannot wait for the opportunity to get out and try it when the current pandemic allows us to move freely where we will

Very robust quality glass, the yield is excellent I attach the shooting test of this filter in combination with the gnd8 from the same manufacturer, highly recommended

My Tiffen 100mm filters are a thicker, and do not fit in the holder. K&F's fit well, but I can't inset my Tiffen Pro Mist into this device. Otherwise works okay.

Merci reçue et satisfaite!
