K&F Concept 67mm Variable ND Filter HD ND2-ND400 (9 Stops) with Putter 32 Multi-Layer Coated Janpanese Optical Glass Adjustable Neutral Density Filter for Camera Lens (Nano-X II)

After several months of use, the filter has a stain in the middle that distorts the image quality by creating color discoloration, the stain cannot be cleaned because it is created between layers that can be seen in daylight. Impossible to contact the seller.There is no warranty policy.

Modifica un poco el color pero nada que sea muy molesto a menos que seas un profesional que necesite que si o si no se modifique ni un poquito el color.

ND filter works perfectly! Used it for my 16mm lens (24mm full frame equivalent) on a aps-c camera. Zero vignetting all the way down to the last stop. Only shows X when you go past the ND400. Even directly only ND400 there is zero vignetting. Perfect for my Sony ZV-E10 II. Highly recommended!

K&F filters are fantastic, work as promised with zero distortion. Made with Japanese optical glass. Reasonably priced filters that are excellent!

Amo este filtro, puedes regular la graduación de ND y al no usar HSS este es la solución perfecta y la calidad de imagen sigue siendo superior, no quita ni un poco la calidad de imagen y es mi favorito en fotos de atardecer que amo hacer Ejemplo en mis fotos de como se oscurece y aclara
