K&F Concept 72mm Variable Fader ND2-ND32 ND Filter and CPL Circular Polarizing Filter 2 in 1 for Camera Lens No X Spot Waterproof Scratch Resistant (Nano-X Series)

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.

I’ve been wanting to buy an VND filter for a while but with so many brands…. I couldn’t decide. I finally made the jump with the K&F thanks to the low price point. I thought, “ant this price I’m not losing annything. Besides I can return it if I don’t like it. let me tell you that I couldn’t be happier. The built in Polarizer gives beautiful colors as you can see in my shots above. It hardly ever leaves my lens. I bought it for my RF 50mm f1.8 and now Im going to get one for all of my lenses.

The ND filter handle is a bit tight. Moving it rotates the circular polarizer and the lens. Definitely not very comfortable when trying to shoot a photo.

The camera filter being reviewed is easy to use and affordable. The reviewer needed the filter to take pictures of cars and purchased it a few days prior. However, upon using it with a Sony A7C camera, they noticed that the colors might be slightly off.Key Features:Easy to useAffordable priceCompatible with Sony A7C cameraPros:Easy-to-use designAffordable price pointCompatible with Sony A7C camera, ensuring proper fit and functionCons:Colors may be slightly off, potentially impacting image qualityConclusion:Overall, the camera filter being reviewed is a decent option for those on a budget who need a filter for their Sony A7C camera. While it is easy to use and affordable, the slight color discrepancy may impact the quality of images. It may be worth investing in a higher-quality filter for those who prioritize color accuracy in their photography.

Overall I gave the product a 4. Reason is that if set at the ND value of ND2 and then adjust the polarizer for maximum effect, the adjusting the fader would cause a change of the polarization through the range. This may be the nature of such a device, but simply set the fader first and the adjust the polarization solves the issue. It may be just a quirk of this unique device. The only "negative" is that I need to find a lens cap to fit if I want to simply let this filter live on the lens. My 67mm cap is too small.

Works great, has smooth action and kills two birds with one stone being able to spin and kill reflections. Only complaint is incompatibility with many lens hoods but oh well, better to reduce diffraction and hit your target than to eliminate diffraction and have to jump through hoops to get a decent shot.

Los filtros ND muy funcionales pero el PL pobre, muy poco eficiente.

To make it short - this combo filter is very good value for money, as long as you're getting it for the right reasons. While not quite up there with "pro-level" filters in terms of quality, it does a great job for what it is.Firstly, the main appeal of this filter is combining CPL and variable ND functions onto one - which saves you from having to stack multiple filters (which may end up not working well together) and makes for one less piece of glass between your lens and your target. I've noticed no flaws whatsoever in how the two functions work together - no Xs, no artifacts. The CPL part of the filter is very, very good. The variable ND part is... fine. Better than a lot of filters in this price range. There is still a slight brownish cast from it, but it's totally consistent and very easy to correct in post-processing. Just don't expect stellar results right out of the camera, without a couple of clicks' worth of extra work!In terms of filter factor, it's more or less spot on - it's a little bit more than 1 stop of light at the lowest setting (ND2), but at the highest setting it seems to be pretty much exactly 5 stops of light - not the 5 and a half you'd get if you took an ND32 filter and put a CPL over it.However, the real question is: do you need this filter? Because the max setting of ND32 is generally a bit too light for landscape photography off a tripod (you'll want an ND64 or even ND100 filter there). For longer telephoto lenses (over 200mm focal length), you really don't need this kind of filter for the obvious reason that you're not likely to be getting too much light. For wide-angle lenses, the CPL portion makes it a complete no-go - on anything shorter than 35mm focal length, it'll completely mess up your image with those uneven shadows (not the filter's fault - but CPL is really not designed for that).So, what is this for, exactly?Well, I can't speak for video usage - but in stills photography there's one area where this filter really excels, and that is for handheld shooting in bright daylight conditions with large, wide-aperture lenses at the higher end of portrait and lower end of telephoto: in other words, lenses between 80mm and 200mm focal length and f/2.8 or less when wide open. This allows you to really control and thin out your depth of field and shoot at shutter speed that will minimize noise, while being able to control more of the stray light from reflections thanks to the CPL.I use it for creative photography with just two such lenses, both totally manual: the Samyang 135mm f/2, and the Helios 40-2 (85mm f/1.5). It is very handy with both, really hits a sweet spot for usability despite how bulky those lenses themselves are, and really brings out the kind of extreme subject isolation and bokeh both of them are capable of. So, if you own monster prime lenses of that kind (between 80 and 200mm, f/2.8 or less) - this is a great filter you really will find useful. But beyond those? Might be worth checking something else!Otherwise, my only other criticisms are about ergonomics: the filter uses some kind of non-standard thread on the outside, and has too little thread left anyway to screw anything over it - so if you were thinking of putting a hood or any other sort of attachment over it, you'll have to forget it. And on too of that, the little "handles" for controlling the ND variation stick out just a bit too far from the body of the filter... so you can't really attach a lens hood behind it either, save for a flexible rubber one - and even then, the "handles" will likely deform it a bit. Long story short - expect this filter to always end up on the very end of your optical train, and expect to have trouble even fitting a lens cap over it without it constantly falling off. It's not a big deal as far as I'm concerned - but you may find yourself putting this filter on and taking it off to store it in a box every time you go out to shoot. Not ideal if you want to put it on a lens and forget about it.All in all though, I'm very happy with it! Worthy buy and a handy tool to use.

Good enough. Works well. Fits.

Bought this for my 35mm f2 which I am using on a Canon RP. I wanted it for slowing down the shutter speed for waterfalls I'll visit this summer, as well as deepening the blue in skies. It works as advertised. Nice metal build quality that feels well made. I like the stiffness on the variable ND part. It stays where I set it, and so far it's working great at reducing the light coming into the camera, allowing me to use longer shutter speeds to get the flowing water effect I was after. I usually use the polarizing part of the filter on the lowest ND setting. I'm adding two photos that I think show the polarizing effect pretty clearly. There is some colour difference between using the filter vs not as well as at different filter settings (rotations). I think this is pretty standard, at least I've observed it in the polarizing filters I've used in the past. I've been satisfied dealing with colour shifting using WB and calibration adjustments on raw files in Lightroom. I don't see any degradation in sharpness. I'm pretty picky and do view files at 100%. Very glad I purchased this filter combo. Great value for the money! I'll also add that I accidentally used it once over a thin UV filter and was glad to not see any vignetting.

Looks great and feel great should do the job when out in bright sunlight.

I'm still learning how to use it and how to get comfortable with ND filters, but I notice this:In 1st image, the lens leaves sometimes some dark circles on the corners, but you can crop it or work on the image during the post-processing. (On my end, it's not too bad)In the 2nd image, I was working in a really harsh light situation, and I used the darkest side of the wheel. (snow reflecting in the water and the sun)The last image is my postwork after using the ND filter.
