It's just amazing. I use it with my Sony A7iii and the 24mm f1.4 Gmaster lens. Updated with some stunt shots later. Definitely recommend this!

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,

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

Great kit for long exposure. If your shooting in bright sunlight it's a great help.

This is one of the best purchases I've made lately, and I have no hesitation in recommending it, especially for travel photographers who are committed to bringing as little camera gear with them as possible. Though sometimes it's better to wear less, but there are things I just can't live without. Filters are one of the accessories that I often carry with me because they are indispensable for my landscape photography. My first impression of the filters is that they arrive nicely and safely packaged. They are packed in a cardboard box and the filter itself is in a hard plastic box inside the box. Except for the circular polarization filter, the frames of all filters are made of an aluminum alloy (the polarization filter is made of an ultra-stable magnesium alloy).

It's easy to use...fits my Zeiss 16-35mm and my 24-70mm and gives me very good results...allowing me to set the right amount of exposure for the effect I'm want !

The metal variable ND filter helps with long exposures and helps reduce some levels. Of course, it is not as strong as an ND 1000, but for shots that are not taken with direct sunlight, it is enough to gently draw water, for example. The processing is top and you can get great photos with it. Includes a cleaning cloth and a super case in which the ND filter does not suffer any damage. (If you don't know: your lens diameter is right on your lens). The filter is also perfect for using DSLR /DSLM to meet the 180° protection rule when shooting. We are convinced ! Simply unscrew the ND filter - done! The lens protection cap also fits

Ever since I started doing bulb exposures, my variable ND filter of choice was Vivitar. It worked great over the years, but I needed a new filter. Since I also own a K&F Concept tripod and they treated me well, I decided to give this filter a try. What's cooler than an ND filter and circular polarizer in one?! And I'm glad I did! This filter works incredibly well. With my old ND filter, I had to stack a separate circular polarizer on top, which would lead to vignetting on my widest shots. With the K&F Concept 2-in-1 filter, this no longer seems to be a problem at 18mm. At 10mm I noticed a very slight vignetting which is almost imperceptible. But it' is definitely a huge improvement over filter stacking. Although it may require 2 hands, this filter is very easy to adjust. It also feels well built and sturdy. All in all, this filter was well worth the money invested.

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.

We bought this 2-in-1 filter for a shoot that was shot outdoors. We encountered no problems filming at the water's edge with the glare of the sun. For the price it's excellent, the variable ND2 to ND32 filter is really sufficient for video. It is possible thanks to the filter to keep cinema look parameters on the camera, with a large aperture, a low iso and a nice bokeh. The filter is of good quality to the touch, we realize that it will not break after several screwing and unscrewing. The advantage of this filter also lies in the 2 small peaks, which make it possible to properly adjust the ND part of the filter. In short, if you want to buy a filter for your camera, we recommend it given its price. Really great!
