K&F Concept ND1000 67mm (10 Stop Fixed Neutral Density) ND Filter with 28 Multi-Coated Optical AGC Glass Waterproof Camera Lens Filter for Long Exposure Photography (Nano-X Series)

Bought it but it's not much helpful for me as a videographer.i am using it on sony a7s3. It 10 stop I mean kind of very dark and there a vintage in left upper portion even I dropped to f1.8 iso640 and 1/100 still. And it's very annoying when you facing towards sun completely balck the vintage is allover. Won't recommend it. Or maybe I don't understand this product use.if I am wrong I will change my review.i tried it it's very dark and I will try now 6 tops nd filter

This ND filter was perfect to begin shooting with. There is very little colour cast and no vignetting. This filter is excellent value for money.

Works as expected. I used it with my Fujinon 16mm f1.4 lens.

Aparecen bandas magenta y verdes en las fotos. Lo he devuelto porque no me sirve el resultado que da el filtro.

Ich bin Neuling auf dem Gebiet der ND-Filter, hatte aber schon ein paar billige mit mehr Durchlässigkeit, die mich nicht überzeugt haben.Dieser hat sich bis jetzt gut gemacht - ich konnte keine Beeinträchtigung auf dem Foto finden. Nur das Auf- und Abschrauben muss man üben. Ich habe mich am Anfang ziemlich angestellt.

It's a filter. It's dark and fits my camera (67 mm).
