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.

Quality filter, there are 5 steps, it is convenient for sunny days, it comes with a leather case with a magnet to close it, the filter is made of glass and not resin, the quality and price are luxury, I have more expensive filters from other brands and they are worse.

For auto rigshots I needed a quality filter at a good price, this would be worth buying at a much higher price! It comes beautifully packaged with a high quality holder for the filter, all made from non-animal products! But none of this matters if it doesn't work, but it does! High quality glass with no tolerable impact on my A7R IV's picture quality. If you need a great ND, this is it!

Since I haven't worked with ND filters before, I don't know what I could complain about here. Overall, I am very satisfied with the glasses from K&F. You get a high-quality, processed filter with top optical quality and a good scope of delivery (artificial leather case).

The filter looks valuable and the packaging is good. Unfortunately, my copy showed clear vignettes in both the direction of ND32 and ND2, making the filter virtually unusable. In addition, the minimum stop was not clean, so that a clear darkening was already visible at minimum (>ND2), only turned a little further did I actually have ND2. So it went from slightly darkened (>ND2) to bright (ND2) to significantly darkened (ND32). It's a shame, but that's why I sent the filter back. I then did not examine the glass quality more closely.

I find this filter ideal for photo and video. But at 10mm on my 80D Crop captUKr it casts a shadow over it. When I zoom a pUK like 14mm it disappears. NO X, no coulUKr dominant. Excellent filter... As advertised. and nice build...

Delivery - Fast, timely and safe packaging. The filter has its own box, so you can safely go out into the wild for photography. Have you ever tried photographing water in direct sunlight? You pass the waterfall and you want to take a great photo, but due to too much brightness your options are limited - believe this has happened to me several times, but with the K&F Concept ND filter the problem is solved. I'm an amatUKr photographer who loves spending time in nature and I think ND filter is something you need to have in your gear ASAP. Being able to adjust how much the filter should be closed and thus get a darker filter is a great thing. The filter is mounted directly on the lens, simply throw it back (note the size of the lens!). You can still take it, it's not difficult and you get great effects with it! Long exposures without an ND filter are a nightmare and having ND filters in your pocket will be an amazing thing. Another thing I would recommend is the mobile app (there are more - just try it) to calculate the shutter speed with the ND filter. You can find the formula on the web, but we need to use the technology correctly. I can warmly recommend K&F Concept Filter!

This is a kit to take seriously if you are a professional photographer or if you are new to photography and want to improve your skills. This incredible filter lets you choose from a range of filter options to add some darkness to certain parts of an image. For example, the sky may appear dark while the rest of the image is light. It offers a stunning effect and can really enhance any image for a professional look. I've been playing around with this over the weekend and it's fantastic. It's pretty amazing how much of a difference lighting can make in a photo. Really very happy.

This is my first square filter! The first thing that struck me was the very elegant and practical packaging - the ring that takes the filter out of the storage box is very clever.

ND-Filter sind teuer, das was jeder der sich damit beschäftigt hat. Hier bekommt man aber für gutes Geld auch ein Top Produkt.
