I've been taking photos as a hobby for several decades, first analogue, then of course almost exclusively digital for 15 years, i.e. I've seen and tried out a number of photo accessories over the years. With the filter I bought here, three things were decisive. 1. The quality, I've spent too much money unnecessarily on useless photo accessories 2. The price, I don't see an point in spending more money which you don't see in the photos afterwards anyway 3. The durability and expansion of a plug-in filter system Attached Image with the graduated gray filter All points speak for this product. The filters are quickly attached, make a stable impression and are supplied in a practical case. The plug-in filter system is more than useful for the hobby photographer. In any case, I wouldn't want to be without it in my photo bag. I can't understand the fact that the filters are difficult to insert, which is often criticized here, on the contrary I even find this important because otherwise the filter could quickly fall through. After more than half a year and several sessions, I can only say about the durability of the filters, so far nothing has been scratched or even broken. Conclusion: Anyone who takes pictures knows that this hobby can sometimes cost a lot of money, and often with this hobby it really is so; "If you buy cheap, you buy twice". However, I don't have the impression with this product that the more expensive competitors, who also offer plug-in filter systems, do it so much better that the surcharge would be worth it here. That's why I can only recommend this system

Very happy with this filter holder set and the ND10. It gives an excellent result. There are no odd hues, and no vignetting either. Very good value for money. Recommended.

This is already my 2nd gradient filter from K&F, I still have the GND 0.8 and am very satisfied. Simply unbeatable for this price. I can't see any color distortion.

I bought this filter along with others in June 2019... I didn't use it until I opened it a few days ago. I found this defect, advances in treatment. I think the warranty doesn't protect me... so I'm warning... if this happens unused... what happens with use...??

The filter has the dimensions of 10x 10cm, weighs 47.5gr and is 2mm thick, so it matches the filter holder of the same company. It is made of anti-reflective glass and allows to eliminate the noise due to artificial lights (i.e. the yellow part that appears at the bottom in the photographs of the Milky Way, due to the artificial lights of the city). The difference without the filter is remarkable, in fact even with a good post production process, the artificial light remains, while with the filter it is completely cut off. In the case of long exposures for the Milky Way, the amount of light captured by the sensor decreases slightly but the raw output is rich in information and allows you to recover the Milky Way and all the starry sky. It is possible to remedy this (i.e. capture more light) by using a star tracker or by taking more shots (in my case, without star tracker, with a f2.8 at 11mm, the maximum time for not obtaining the movement of the stars is 30 seconds). Even in the city it does its job by eliminating that yellowish gradient in the sky and bringing out the beauty of the night lights.

Perfect and good price quality

Super filter and cheaper than competitors. Would I buy again.

Very good. At a glance, the product looks very good. In the absence of testing the filter in clearer conditions, I tried it with gray days as we have now.

I needed this filter and the quality and price is second to none.

For safe storage of three square filters 100 x 100 mm and a filter holder. The case seems sturdy and looks pretty good.
