I have utilized my filter for a variety of different shots and am continually amazed at the image quality I am able to produce. This was worth every penny I spent on it.

Currently use this filter for my Sony A7iii for my videos on social media. Great value for the price and the quality is incredible.

In my search for a 105mm vnd that doesn’t cost more than a new lens, I came across this. I wish there were hard stops & that the darkening were more linear (is that possible?), but otherwise it’s basically perfect. Only a very slight x vignette at max strength; very little color shift if any.

Camera - fx3 in slog3 shooting in 4K 4:2:2 10bit 24fps 1/50, 640 iso f1.4 on a 40mm sigma art.With the nd set on its darkest setting with the above settings on a very bright day it’s slightly over exposed with the aperture wide open. If I close it a little to f2.8 it’s a little under exposed in which i need to open the nd filter slightly.This does work really well for video work, it does have a slight color cast but it can be remedied either by adjusting your wb or just fix it in post. It’s negligible if your shooting in log. It doesn’t have hard stops so it does have an x if you go past the working ranges. And if you’re new to ND filters without stops, this doesn’t mean that the filter doesn’t work, it just means that you have to pay attention not to go past. Another thing worth noting is that the markings on the filter are not accurately lined up so it’s best to just either make your own markings or make notations on the ring to tell what is fully closed and what is wide-open without the X appearing. It’s honestly a great ND filter minus the lack of hard stops. The only other annoyance is that it doesn’t come with a cap but K & F does sell one for their older models that will fit this newer model, but you will have to cut a notch in the cap for it to fit correctly. I added a picture of this. I chose this over going with a polar pro due to cost effectiveness, and I’m not upset about it. There is another version of this filter that goes one stop darker up to nd1000 that I was considering getting. But my fastest lens is a 1.4 prime. If I had anything less than that and I wanted to shoot wide-open I would get that filter instead.

This is my first time photographing with a filter. I was traveling to Croatia and wanted to get some nice scenic shots.Not sure if it was user error, a product issue, or a commonality with other filters, but I found the lens would give off weird vignetting and it took five or so mins to adjust accordingly. Again, this may be a common issue with filters but it took a lot of trial and error to get the shot I wanted. Sometimes I forewent the filter and snapped the picture anyway.However, at the price advertised, I’m not upset with the results I ended up managing to capture.

No weird color shift or severe x pattern. Best for the money

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.

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.

El filtro K&F Concept Nano-X ND variable ha sido una adición impresionante a mi equipo fotográfico. Con un rango de ND2 a ND400, tengo la flexibilidad de ajustar la exposición en diversas condiciones de luz sin necesidad de cambiar constantemente de filtro. Lo he probado en varias sesiones al aire libre y me encanta cómo me permite controlar el efecto en el agua o en el cielo, dándome ese toque profesional que siempre busco en mis fotos de paisajes.La calidad de la construcción es excelente, y el vidrio es muy nÃtido; no he notado ningún efecto de viñeteado ni pérdida de detalle, incluso en los niveles más altos de densidad. Además, la rotación del filtro es muy suave, permitiéndome ajustar con precisión sin problemas.Otra cosa que me ha sorprendido gratamente es lo delgado y liviano que es. No se suma peso a mi cámara y no ocupa casi nada en mi bolsa, asà que puedo llevarlo a todas partes sin pensarlo dos veces. También agradezco la capa antirreflejos, que realmente ayuda a reducir los destellos y mejorar el contraste, especialmente en condiciones de mucha luz.En resumen, recomiendo el filtro K&F Nano-X a cualquiera que quiera calidad, control y flexibilidad en sus fotos. Es una herramienta esencial para cualquier fotógrafo al aire libre que busque llevar sus imágenes al siguiente nivel. ¡Muy satisfecho con esta compra!
