Brand Story
K&F Concept 100 x100x2mm Square Light Pollution Filter
• Between mercury vapor, sodium, and low CRI LED streetlights, there are many undesirable wavelengths of light that pollute the night sky. The glow from these can keep your camera from seeing the sky properly and ruin your night images. The new K&F Concept Filter is available for DSLR and DSLM photographers in 100mm and 100mm widths and helps to reduce the effects of light pollution.
• The special coating on the filter helps stop the yellow and orange wavelengths of light from entering the lens resulting in clearer photographs of the night sky.
• For architectural shots or long exposures in the urban environment even delicate structures and contrasts are maintained in the subject and no longer overexposed.

Very effective filter
This is a solid ND filter. I've recently started using square filters instead of circular filters. Below is some of the longer exposures, I shot with this filter. I'm still learning photography, so this filter has been really good to practice with and it helps me progress and learn with my longer exposed shots and photos. Would highly recommend for anyone looking to improve their photography.

Top price-performance
I'm extremely happy with the filter; it does what it's supposed to without any color changes. I use it in a Rollei filter holder and it works without any problems.

Very good value for money - minimal staining
The ND 1.8 filter is very good for its low price. The filter makes the image slightly bluer. This deviation can be quickly corrected in both photos and videos.
No loss of sharpness.
The filter can be used in a 4x4 inch matte box, although 100x100 mm is actually a bit too small.
Compared to 4x4 filters in the €200 range, I think it's excellent value for money.

Best filter among the cheap ones
I am a photographer and, in my travels, I also deal with landscape. Over the years I have had the opportunity to try and test filters of different brands and qualities. Quality naturally has its price and from this point of view K&F has never disappointed me. In the filter sector it is the brand with the best quality/price ratio. I have had the opportunity to try this filter for long exposures and it is one of the most valid ever seen. The glass is of excellent quality and does not cause any loss of sharpness. It arrives in its specially protected imitation leather packaging. It has nothing to envy to more renowned and expensive brands. I would like to underline that I have not noticed any color casts or strange aberrations. If you add an unmatched price, I can only recommend this filter.

It came with the 10 stop glass filter and seems to be pretty great quality. I'm loving using it. Even ordered a 6 stop to go with it.

That's fine. The polarizing filters also have a rotary thread on the front where the filter plug-in system can be attached.
