Brand Story
K&F Concept 100 x100x2mm Square Light Pollution Filter
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.

Great filter for reducing light pollution
Loving this filter! Fits perfectly in my holder and greatly reduced the amount of light pollution and makes the stars really pop. Highly recommended it to anyone looking to bring out their astrophotography

Good quality product well priced
Just received this so haven't been out and tried it yet but I've compared it's colour tone to a (much more expensive) Kase 150mm filter which makes me believe it'll be fine. It's packaged really well and has a brown leather-style pouch to store the filter which actually fits quite nicely into my Lowepro filter pouch - I think I'll keep it in that even in the pouch, not only to protect it but I'll be easily able to spot it in the dark! This glass filter fits perfectly in both my Nisi and Lee holder systems so I've given it five stars for the build quality and the fact it looks like it'll do what I need. I'll adjust this review if I discover otherwise when I've taken the first batch of photos with it.
