this is perfect if you take photos during peak sunlight. It basically gives your camera sunglasses. the filter quality is great and doesn't degrade the quality of your photo. If you've ever taking a photo outside and everything looked dark then you need an ND filter. I used this on the RF35mm f1.8 and noticed a little vignetting but this can be corrected in post. Since it's variable you can adjust the filter on the fly depending on how much light there is. The adjustment goes completely around so if you spin it all the way one way it'll take you from light to dark since there's no hard stop. It also comes with its own hard case so you can store it away in your camera bag without worry.

I'm just a beginning photographer and am taking classes at my local community college (which I highly recommend for anyone else starting out like I am). I have an assignment for a long exposure photograph which most of the class is going to do at night. I wanted to try something different so I bought this ND filter for my Canon EF 17-40mm f/4L lens and I'm really happy with it. It worked exactly as I had hoped and I was able to get a picture of a nearby artificial waterfall in bright light with a 30 second exposure. The water has a nice creamy texture to it, but the rest of the image is sharp.

I wish the adjustment worked a little better with clear stops and the inability to go beyond Min and Max. I also can't remove the hood once the filter is on because there is a small rim that extends beyond the edge of the lens. Other than that, I'm very happy with this filter.

was skeptical purchasing a filter that was on the cheaper end, and boy did this deliver! Bought for a vacation to capture long exposures in direct light and it works great! Adjustable apature ring, highly recommend!

From the packaging and presentation to the build quality and functionality, this is a very solid purchase. I am very pleased with this filter and plan to order more from K&F Concept in the future.

Filtro ND variable, 2 discos filtro que al girar polarizan el paso de luz de tenue a oscuro
En montura ecuatorial y/o alt azimutal en conjunto con adaptador Vastar permiten hacer sesiones de fotografía de salida y/o puesta de Sol.
El filtro de 72mm permite proteger todos los sensores de fotografía del celular de la luz incidente del Sol, pero también es recomendable hacer adaptaciones caseras para proteger el celular por completo como se muestra en las fotografías.

It's a very good variable ND filter, very useful and the images are clear. Used it when we went to Great Falls MD to take pictures of waterfalls.
Great Variable ND filter
