These pictures were both shot with an 1.4 aperture in the middle of the day at a shutter speed of 400. Normally to use F1.4 during the day I essentially have to max out my shutter speed just to get something semi usable. And even then the exposure is usually blown out. But with my shutter speed not even half way maxed out I’ve got a completely usable photo that with room to further fine tune if needed. Plus I have the added benefit of having a polarizer lens so I won’t have to worry about reflections in that harsh lighting! Honestly get it. There’s no real reason not to.

It is a variable and polarizing ND filter. The ND is 5 steps, there are double, 10 steps (ND1000, 1024 to be exact). The polarizing filter eliminates light reflections on surfaces, cars, water, glass, also enhances the colors of the sky, leaves, asphalt, etc... (for more information search the Internet ) I personally use it for video, so as not to lose aperture-closing depth of field (f9 forward, now I can go to f2.3 without burning the frames due to excess light). I haven't removed it from my 35mm in a while, I'm delighted. The filter is made of metal and glass, presented in a rigid plastic case for storage. You can see the protective and anti-glare layers of a greenish color and you can put the dingle on it which holds quite well without staining. The lever changes the density of the filter and the other ring moves the polarizing filter. You have to be careful with this because you can move both carelessly. In the pictures you see the filter attached to an adapter, (step-up 49mm to 67mm) this is because I have 67 and 49 filters, my advice is to buy large filters then "step-up" adapters ". On image quality. Well, excellent: there are no casts, no chromatic aberration, no loss of definition or the terrible X of the ND gradual filters appear. I have a very expensive polarizing filter and barely notice the difference on it. As a negative point although I have already said it,

Dear kF, I want to thank you for your follow up message regarding my satisfaction on my order. You really care about customer service and really appreciate that...the ND 67mm is amazing and I'm very happy with it. I know this is about reviewing the product, but I'm so grateful that I went above and beyond for your customer and it's priceless. I recommend this product and the shopping experience. Thanks for doing it right.

I've been using this CPL/Density filter for about a month and it's amazing. I do inventory photos for a few dealerships and it works great in harsh light and balancing/removing reflections. As for its use on landscapes and portraits, it really helps to tone down the highlights to give better editing control and to deepen other areas of color that you often lose. The only downside is that I can't use my sun visor for "shock protection" because you can't use powerline with sun visor. Currently using this filter on a Tamron 24-70 G2

I purchased this specifically for shooting landscape photos on a recent vacation. Photography is a hobby for me not a profession. I was very pleased with the outcome. Settings used for photo included in this review were: ISO 250; Exposure 1/13; Aperature f/18

K&F Concept 67mm Variable Fader ND2-ND32 ND Filter and CPL Circular Polarizing es un filtro muy versátil y de alta calidad que ofrece una serie de características útiles para los fotógrafos.

Lo primero que destaca de este filtro es su capacidad para ajustar la densidad de la luz que entra en la cámara, gracias a su rango variable de ND2 a ND32. Esto permite controlar la cantidad de luz que llega al sensor, lo que resulta especialmente útil en situaciones de alta luminosidad, como la fotografía en exteriores o en condiciones de iluminación intensa. Al ajustar la densidad, es posible obtener exposiciones más largas, lo que facilita la captura de efectos como el movimiento del agua o el desenfoque en fotografías de paisajes.

Además de la función de filtro de densidad neutra, este producto también incorpora un filtro polarizador circular (CPL). El filtro CPL ayuda a eliminar los reflejos no deseados y mejora los colores y el contraste en las imágenes. Es especialmente útil al fotografiar paisajes, donde puede realzar los tonos azules del cielo, reducir los reflejos en el agua y resaltar los detalles de las nubes.

En cuanto a la calidad de construcción, el filtro K&F Concept está fabricado con vidrio óptico de alta calidad que proporciona una excelente claridad y nitidez en las imágenes. El anillo de ajuste suave facilita el control de la densidad de forma precisa y sin esfuerzo, lo que permite realizar ajustes rápidos durante la toma de fotografías.

Es importante tener en cuenta que, al ser un filtro variable, puede haber una ligera degradación en la calidad de la imagen en los extremos más densos del rango. Sin embargo, en general, este filtro ofrece un rendimiento sólido y resultados satisfactorios.

Super happy with this purchase for the price you can get quality photos that will stand out from the rest.

As far as using it on Landscapes and Portraits, it really helps with toning down highlights to give some better control in the editing and deepens some other areas of color that you often lose.
Only down side is, that I’m unable to use my lens hood for “bump protection” because you can’t use the CPL with hood. Currently using this filter on a Tamron 24-70 G2

It is a variable ND filter and polarizer.

Personally, I use it for video, so as not to lose depth of field by closing the diaphragm (f9 onwards, now I can go to f2.3 without burning the frames due to excess light). It's been a while since I took it off my 35mm, I'm delighted.

The filter is made of metal and glass, presented in a hard plastic case for storage. The protection and anti-reflection layers of a greenish color are appreciated and you can put your finger on it, which holds up quite well without staining.
The lever modifies the density of the filter, and the other ring moves the polarizing filter. You have to pay attention to this because it is possible that you inadvertently move both.

In the images you can see the filter attached to an adapter, (step-up 49mm to 67mm) this is so because I have 67 and 49 filters, my advice is to buy large filters and then "step-up" adapters.

About image quality. Well, excellent: there are no dominants, no chromatic aberration, no loss of definition or the terrible X of Gradual ND filters.
I have a very expensive polarizing filter and I hardly notice the difference over this one.

As a negative point, although I already said it, be careful when manipulating one of the rings so as not to move the opposite.

**If it has been useful to you, remember to vote positively in this way we will be helping each other.** :)

I purchased one of these filters to try it out because I was tired of stacking a fixed ND & a CPL filter.
I fell in love with the results & bought 4 more in various filter thread sizes so that all my lenses had one of these CPL+VND filters available without the need for a step up ring.
100% worth the investment for both photo & video of automobiles or really anything that would benefit from having this level of control over both your ND & CPL at the same time.
I use one of these filters for LITERALLY every single outdoor daytime shot not, EVERY SINGLE ONE WITHOUT FAIL.
Can't say enough good things about these filters for my line of work!!!
& yes, I paid out of pocket for all the filters, not sponsored.
